Those orange-cloaked fools you saw hanging off the CN Tower, actually paid for the 'privilege'. You can do it too! The 'attraction' is called EdgeWalk http://www.cntower.ca/en-ca/plan-your-visit/attractions/edgewalk/edgewalk-overview.html
Upgrades or not?
Richard you could win a few bar bets with this one :-) I looked at this very closely a while ago (I was interested in how much value was added by a 5-card suit in a balanced hand) and the results were a surprise. I used sound methods with large samples ...
Upgrades or not?
"xx" is a major defect, you're better off with 4333 all stopped. Tens simply make any hand stronger, each is adding 1/2 point or so. So clearly (1) qualifies, (2) is close, but kick (3) to the gutter.
Odds of number in a suit when pard opens a short club
For that line I'm getting 10.1 25.2 23.8 27.4 13.5 Just did a 2nd 10K to get 10.1 26.0 24.6 26.2 13.2 For any practical purpose, I don't think a difference of a point or two up or ...

Odds of number in a suit when pard opens a short club
Of course you don't have to be the opener's partner, you might be overcaller. If you're looking at 5 clubs, the chances of opener holding 2,3,4,5,6+ clubs are 21,38,22,16,3 percent.
Odds of number in a suit when pard opens a short club
Partner opens 1. I’ve defined that as 11+ unbalanced, 12+ balanced, 2+ clubs, max 4M, extracted 15-17 balanced, should be close enough. When you have 0 clubs, partner will have 2,3,4,5,6+ clubs this many percentages 3,10,17,32,38. So if you hold ...

Great summary! The only thing I would add is the PATH system, a pedestrian walkway to which the playing site is connected. PATH will take you at least close, to just about anywhere you want in the downtown core. There is something like 20 miles of walkway, and 1200 stores ...
Jim Munday Wins Another BBO Individual Practice Session!
When the human player consistently opens 1NT with pretty much anything at all (I'm given to understand), then those bids are no longer 'psyches' or 'tactical bids', they form part of his system. The bots on defense are entitled to know that system, otherwise it isn't bridge that ...
Jim Munday Wins Another BBO Individual Practice Session!
No, and that is the major problem. The bot sims a bunch of hands with 15-17 HCP, and of course they screw up the defense (even moreso) when declarer, who opened 1NT with 12 unbalanced, must have this card or that, and doesn't.
