NABC Online Individual - Day 4
(Page of 15)

This is the last of 4 articles, see http://bridgewinners.com/article/view/nabc-online-individual-day-3/ for the most recent and again I'll be covering 75% or better and 25% or worse hands.  Coming off a rough third session, how would the last session go?

We start off with an A+ board for letting partner's diamond preempt be the strain after one attempt at a thin game, Follow with an A+ board for making a game the computer could have set, a dead average hand for being in 3nt where 8 tricks is the limit, and another A+ for getting 200 defending 3.  The first qualifying hand is board 5 where we get to defend a 2 contract:

Double dummy 8 tricks are there, but after the auction I try the Ax in partner's suit, but seeing the dummy and the J from declarer switch to clubs.  When partner wins the Q and switches back to diamonds (in case I had stiff A maybe) declarer gets a club pitch from the long clubs.  I'm not sure if the 9 from partner is a suit preference, or random, or system, but declarer decides that cashing the 3rd round of diamonds is a good idea and I get to score a cheap ruff and they are now on the path for going down.  I play another club to partner's K, and now the T is a possible promotion card while declarer ruffs high.  With the bad split of trump declarer gets only one club ruff and a long club but is forced to lose 2 spades in the end for down 1 and +100 is good for 80.43%.

The complete traveller was:

3DS= 1 110 100.00%

2HE-1 7 50 80.43%

3HE-1 1 50 80.43%

3DS-1 4 -100 54.35%

2HE= 7 -110 30.43%

2HE+1 1 -140 13.04%

4DNx-1 1 -200 8.70%

3NS-3 1 -300 4.35%

4DNx-2 1 -500 0.00%

Some of the folks that let the contract made started with the A but then switched to the A and didn't have the entries to partner to setup the diamonds through shortening the trumps the same way, and with the diamond threatening pitches the spade AQ go early making the J good for declarer too.

We follow this with an A+ for being in a heart partial but sneaking a 10th trick.  We then encounter our first disaster for taking a little non-field action that has some risk, the risk coming through, and then us playing it wrong on top of that:

We open 1 and when our RHO bids 1 it is passed back to us all red.  We know RHO has at most 13 hcp due to the best hand constraints.  It seemed to me that selling out to 1 when we likely have half the deck might not be great and I decide to double even with the 3=4=4=2 shape and just hope partner doesn't pick clubs with a 4 card suit.  Being all red, maybe this is too agressive, and the pass certainly worked out better when partner is 3=3=3=4 and puts us in the 4-2 fit violating Burn's first law.  We could have got out for down 2 and a very bad score, but end up down 3 for an even worse score of 12.5%.

The complete traveller was:

2SW-1 2 100 97.92%

1SW= 4 -80 85.42%

2CN-3 3 -300 12.50%

2CN-4 2 -400 2.08%

Accurate defense against spades holds them to 7 tricks, but even 8 tricks is above average.  The 2 people came about from opening our 13 count 1NT and getting W to bid 2 over that.

Next hand partner beats us to 1:

We clearly want to be in at least game in spades but need to figure out if we show our stiff K, or side source of tricks, or just plain old Jacoby 2nt.  I choose the J2NT partially because I know partner is limited by no stronger than 14 hcp so slam is remote without good shape.  When partner responds 4 we play it there.  Thanks to the opening lead being a and not a we are able to arrange a pitch on the hearts before trying the losing trump finesse so we get 11 tricks and +450 scores 76.09%.

The complete traveller is:

4SN+1 7 450 76.09%

5SN= 5 450 76.09%

4SN= 9 420 30.43%

3SN+2 1 200 8.70%

5SN-1 1 -50 2.17%

6NS-1 1 -50 2.17%

If you splintered in hearts you'd get the club lead, if you bid 2 before supporting spades you'd get a heart lead, and most of the people who make 10 tricks got a red lead but just attacked trumps before pitching on the club and when E is in with the K knows what to do.

Next we get a great result for making a major game with 4 top losers:

Over partner's 2 preempt we have AKx of hearts, a side stiff, and AQ-sixth and decide to risk the 4 call.  Against this blind blasted auction E leads the A and crashes with its partner's KQ tight and our 4 outside losers become 3.  They cash their 3 tricks (thankfully the diamonds aren't transportation for the 3rd round club ruff) and we can pull 2 rounds of trump, still get our diamond ruff from the short hand, and get back to hand to pull the trump and have only winners left.  +420 was worth 84.78%.

The complete traveller is:

5DWx-2 1 500 100.00%

4HN= 6 420 84.78%

3HN+1 1 170 69.57%

3HN= 1 140 65.22%

4HN-1 11 -50 36.96%

3HN-1 1 -50 36.96%

4HN-2 1 -100 6.52%

4HNx-1 1 -100 6.52%

5DWx= 1 -750 0.00%

If we bid 2 over the 2 W can stick in a 3 bid and that leads to some of the diamond contracts, and same thing if we pass or bid 3.  If they get the diamond bid in, now a diamond lead means they don't need to crash the club honors.  But most of the down 1 in 4 come from the same auction and lead as at my table, people just either fully pull trump and forget to ruff the diamond or else win the first two rounds of trumps with the AK of hearts and then try to cross in clubs and suffer the ruff from W.

We have another choice on what to do with an 11 hcp hand that is a little surprising and lucky:

My thinking 2nd seat is if we pass there is too much chance this is passed out, and again I know partner is in that 7-11 hcp zone, so I decide to open the 3433 11 count.  I debate briefly 1 with the really good 4 card heart suit, but decide 1 is probably best.  When partner bids the 1 I consider passing, but decide to continue on and show the balanced hand with 1NT.  When W now tries 2 natural, partner shows a second suit, and when we preference back to spades partner shoves us to game with his 10 count.  We are down on a club or top diamond lead, but the heart lead gives us chances.  We take advantage of both the fact that W bid and also the fact that the computer doesn't like to lead from K to choose the ruffing finesse in hearts over the opening lead finesse and this sets up some pitches for us.  On the trump play W tries to break clubs but it is a bit late.  I'm not sure I can afford to pull trump fully because I worry that when we attack diamonds the clubs will force us, so I pull one round of trump ending in S to try to pitch clubs on the good hearts.  We get one pitch but then W ruffs in, but we can over ruff and maintain some trump control.  We play on diamonds and with the AQ onside we are good for making, with +620 being worth a cold 100%.

The complete traveller is:

4SN= 1 620 100.00%

2DN= 1 90 91.30%

P 20 0 45.65%

2DN-1 1 -100 0.00%

Nearly everyone did the normal pass out.

I get an A- for being in game making without the overtrick for misplaying the elimination suit (J86 versus AT5 shouldn't lead the J), This brings about another which game and how many tricks boards:

We have a pretty standard auction to 4.  On the play the opening lead lets us try the very unlikely to make opening heart finesse.  Before pulling trump we use the transportation to take a few side working finesses, and then when Kx of trump is onside, we end up with all the tricks. +710 is good for 76.09%

A fair number of NT choices from people, and a fair number of people slip a trick in the play.

Next hand is a slam where we get lucky in a couple of places to make all the tricks:

We have an 18 count and partner opens 1M with us having 3 card support.  We go through all the suits and show the heart fit with 3.  When partner cues clubs we are off to slam, and over blackwood we confirm all the keycards and the Q but settle for 6.  The opponents have been silent, so I'm not sure about all the shape, but after winning the opening lead decide that a club ruff, with a club on the second spade would handle the black losers and then it is just up to the diamond finesse for making 6 or 7.  But on the third round of clubs when I ruff W pitches.  On the one hand this is great that there is no over ruff, but on the other, this has me a bit worried.  I decide I want to pull all the trump now, but this leaves me stuck where I haven't played on the second round of spades yet to pitch the club loser.  I was worried about that club loser and now forgot that W had showed out of clubs.  So I should take the diamond finesse knowing that W can't play the clubs if the finesse loses.  Instead I decide I'll conced the diamond K and just cross to the A to take the sure pitch before losing the diamond, and low and behold the stiff K falls.  I should have had the A+ for 1430 but +1460 is instead worth 91.30%.

7HN-1 1 -100 6.52%

7HN-2 1 -200 0.00%

Only about half the field were bidding and making slam, so the overtrick was the icing on the cake.

Next we get an A+ for our 8 card spade suit taking 11 tricks, then we take another anti-field position with suppressing a 4 card major in a weak balanced hand.

Again I like getting to 1NT quickly with the weak nt and here this helps W lead a spade and we win an early spade trick, to go with the 3 top hearts and diamonds to guarentee the contract.  We then exit in spades and W rises A but then E unblocks the K and suddenly our J is surprisingly good for the 8th trick. +120 is worth 95.65%.

The complete traveller is:

1NS+1 3 120 95.65%

3NS-2 1 -200 2.17%

Double dummy playing from the more common N side shouldn't impact the expected 7 tricks, but it is tricky and probably need opponents to break spades or diamonds for you - supressing the Jxxx of spades and having them lead them on the go makes it much easier.

Next we get a defensive top for finding down 2 on a board that should make:

We sell out to 3 and pound on the hearts shortening him in trumps.  He finesses in to us and we continue hearts.  When he plays a club up we play low and his T wins.  He now ruffs the last heart, and cashes the spade A!  Now when he plays the club it is clear that I can win the A, pull trump, and get 2 heart tricks and the guarenteed set and partner still gets a trick with the KQ of diamonds.  +200 is worth 100%.

Some of the time the contract made was because people led the 4th best heart instead of the sequence and then declarer doesn't cash the spade A.  Sometimes the reason is people attack diamonds when they win the spade J.  The down 1 people rose with the A on the first round to play another heart and now declarer drifts 1 off when they play a diamond to the A with N keeping the KQ for winners.

Next comes a dreaded strong 6331 with 3 in partners response suit.

I choose to try 2 on the AKx suit.  Partner raises this to game.  W attacks spades and it becomes clear how the suit lies.  I take the early heart to setup that suit before stripping the trumps and essentially playing at NT.  When clubs don't split like I had hoped I settle for making exactly and +420 is good for 84.78%.

The complete traveller is:

If I would have tried the 3 rebid, I would have played it there.  2NT rebid would have fetched 3 and I could choose the game.  A bunch of people opened the hand 2NT and got to play 3NT.

Next partner makes the good choice to avoid the 5-4 major fit since we are 4333 opposite 5332 with a little extra strength.

N/S +660

Over the J2NT I evaluated us a 3nt response and partner passes.  There are 11 tricks in NT or hearts, so this is a good spot and +660 is worth 97.83%.

The complete traveller is:

3NN+2 2 660 97.83%

4HS+1 17 650 54.35%

5HS= 1 650 54.35%

4HS= 4 620 6.52%

Most people replied 4 over 2NT and played it there.  Some opened 1NT with our hand and then played in 4 on a stayman auction.

We had a near flat board following this defending a partial then have another right strain, right level, right tricks hand:

There is a lot of bidding by the time it comes to our hand and we choose to make the responsive double to keep both hearts and clubs in play with Qx of partners suit as a fall back.  Over the hearts we show the club strength but let 4 go as a final spot.  Not much to the play with a loser in each major, and +650 is worth 80.43%.

The complete traveller is:

4HN+1 5 650 80.43%

5HN= 1 650 80.43%

4HS+1 3 650 80.43%

4SN-3 1 -300 0.00%

The 5 people are ones that bid 4 or 5 instead of X at our first chance.  The various slam people basically drove their on their own.

We follow this with an A+ for defending when W balances over partners 4 opening and goes off 3 (the smart folks X, the unsuccessful bid 5 level).  We follow this up with back to back A- for going down in reasonable contracts, the second time down 2 when down 1 was available.  The final board of the session is again a which strain and how many tricks hand:

We have to choose between X and 3 over the opponents preempt and decide to show the 5 card major.  When opponents compete to the 3 level we balance back in with the X and partner puts us in the heart game.  We lose the 2 obvious spades on the go, but on the diamond switch rise A as we think the diamond is likely off given the weak 2 bidder already had AK of spades and there is some chance this is a stiff diamond.  We pull a round of trump and want to take the club finesse after pulling all the trump, so we play one round up to guard against stiff Q off or a first round ruff and the Q appears.  We now can pull trump and run clubs for the rest and +450 is good for 80.43%.

The complete traveller is:

4HS+1 10 450 80.43%

4HS= 6 420 45.65%

4CN+1 3 150 26.09%

4CN= 2 130 15.22%

3SE-1 2 50 6.52%

4CN-1 1 -50 0.00%

If we X the first time we hear 3 - P - P and now our second double fetches the 4.  The people with 10 tricks lost the diamond K.

So overall on the fourth day I finished around 1 hour 33 minutes finishing around 2:48 am Toronto time.  My provisional score was around 72.8% and then 73%, but as like with all the other sessions, it fell significantly as the later results came in, and ended up with a still good 69.93% which was 13 out of 2428 players.

If you break down the boards into quartiles I had:

12 greater than or equal to 75% up to 100%

7  greater than or equal to 50% but less than 75%

4 greater than or equal to 25% but less than 50%

1 greater than or equal to 0% but less than 25%

13 of which I covered here.

Dividing in to quintiles instead I had:

10 greater than or equal to 80% up to 100%

8 greater than or equal to 60% but less than 80%

3 greater than or equal to 40% but less than 60%

2 greater than or equal to 20% but less than 40%

1 greater than or equal to 0% but less than 20%

So overall this was a great session with fewer mistakes and a couple of lucky results too.

So overall for the event these 4 sessions combined for a 63.38% which was good for 36th out of the 2428 who completed all 4 days.  This paid 4.68 masterpoints.

If you do some combinations across the 4 days then:

If you break down the boards into quartiles I had:

40 greater than or equal to 75% up to 100%

30 greater than or equal to 50% but less than 75%

16 greater than or equal to 25% but less than 50%

10 greater than or equal to 0% but less than 25%

50 of which I covered here in the 4 articles.

Dividing in to quintiles instead I had:

31 greater than or equal to 80% up to 100%

29 greater than or equal to 60% but less than 80%

15 greater than or equal to 40% but less than 60%

14 greater than or equal to 20% but less than 40%

7 greater than or equal to 0% but less than 20%

There were a few things I learned about the robots, like be careful about assuming your partner doubling with a "biddable suit" in this doubled contract actually has the trump stack you might want. And that turning on the confirm bid was a good setting for being able to see the meaning of lots of bids on my tablet without accidentally taking the wrong one.

There was the question about declaring versus defending.  On these hands I declared 76 times and defended 20 times.  On the 20 hands I defended I averaged 55.55% while on the declaring hands I averaged 65.44%.  Some of that is likely from all the times I doubled the computer and they made it (at least 3 or 4 hands).

One thing that I found interesting is how my provisional scores dropped each day about the same ~4%.  I also noted that I was playing relatively early in the playing day, but yet I never found that I was the first person to play any boards, so I sort of assume that the provisional results are pre-seeded with what GIB would do on the boards, since usually when I finished there were exactly 2 results on every board (mine and someone else, I think GIB).  If that is the case, I wonder if that suggests that GIB would actually be below average in the field?

In terms of value for money I played the 96 boards in just under 6 hours total (or about half as long as it has taken me to write these 4 articles - and I'm only profiling about half the hands - I don't know how Richard Lawson was able to do all of his sessions so quickly each day) and it cost $40 with the early registration.  This seems a lot relative to the likely cost of running this event and when measured by $/hour or $/masterpoint.  But with 96 boards the cost per board is less than 50 cents.  In the NABC+ it is generally $1/hand/person - and with 4 people at a normal bridge hand collects $4/hand, while this is only collecting the less than 50 cents/hand.  So this does seem to be giving ok value/price point compared to normal NABC+, NABC, and regional events.  Plus the turn out was great with more than 2500 who participated in this at the $40/50 price point - which is almost as many people as participate in an in person national tournament and certainly more than participate in any one event at the nationals.

It was definitely an event I'd be willing to play in again.  I'm still a little suspect of the "best hand" treatment and I think it might be an even better event with random hands, as the majority of the creative or off center plays come about through the knowledge about "best hand" and how that impacts the hand.  But still overall I think 90+% of the boards that I played were the exact same as if I was playing with a human and against a human.

I also wonder how the event would work if it was like a national event with cuts so that the field became stronger and more unified as the event went on.  There could be issues with the greater overlap of hands if there are fewer players thanks to the cuts, but it might be interesting to see as well.

I do hope that there are other versions of events like this at other nationals or even at other non-national times of the year.  

For instance, there is a need for a Fall grassroots event IMO and a flighted district individual event (like GNT or NAP) that you qualified in by playing robot individuals at the club/unit/district level, but that had a national final of human f2f individuals amongst those that pre-qualified might be an interesting format to try.  Or you could do robot all the way, with the national final in person or with everyone playing the same hands at the same time to have the final field comparisons be just amongst that highly pre-qualified field.
