Another round robin defensive problem
(Page of 3)

You wisely choose not to overcall 1 vulnerable at imps with a poor suit and not much of a hand. The opponents play transfers over 1 so presumably 1 showed and 1 showed a weak NT with 3

Now you are defending a heart game and partner leads the K. You and partner play upside down signals. Click the next button in the diagram and now plan the defense.

It seems normal to give partner a ruff, but do you see how that makes declarer's task easy? This is declarer's second suit which he needs to do something with, so you are helping him if you continue it, especially since partner has the third trump not you. Here is how that went at another table. Note that the South hand is declarer at this table.

Even if East had found the club return, Declarer can ruff the next diamond high and draw trump.

So what else can be done?

Declarer still has to knock out your A and draw trump and deal with all his diamonds. So perhaps tapping him in spades will give him some trouble. That is what Andrew Robson of England did and his partner Tony Forrester continued the treatment. Look what happened:

Apologies for featuring Robson yet again but that was the match I watched yesterday since USA2 was not on vugraph and USA1 was already qualified. Now to go look at this hand in the other matches ... more later

Dawei Chen of Japan also found the non ruffing defense also against Monaco, of the 20 declarers in 4 most made it and there is no data for the others that went down except for South Africa vs USA2 where a different line was chosen

http://worldbridge.org/repository/tourn/bali.13/microsite/Asp/BoardAcross.asp?qboard=025.20..980

In the Venice Cup 21 of 22 tables played 4, the other saved in 4 but there is no data on the unseccessful declarers except in England vs Japan where the different line was chosen

http://worldbridge.org/repository/tourn/bali.13/microsite/Asp/BoardAcross.asp?qboard=025.20..981

Over in the Senior, we have more variety, some 3NTs, one 6 and a 5 and again not enough data for the 8 out of 18 tables where 4 went down
