精彩防守赏析：忍让

[lycier]

今晚我同俱乐部的几位朋友开桌打牌，其中这副牌的防守堪称精品，值得大家好好学习。

像这个6nt做庄，第一顿放过，2-3分配的话，后面就顺利了。

When holding Axxx trump with 4-1 break facing a 5-3 fit, it is usually adopting a forcing game (as the opening lead suggest) and thus by ducking twice one can effectively pose a dual threat:

- eliminate the trump policeman if declarer insist to draw three round of trumps, and continue the forcing game

- ruff declarer's winners with the small trump if declarer stop to draw trump

 

For the actual hand it is quite interesting if NS is defending 3♠ instead: South need to take the ♠A on the 3rd trick to gain a vital tempo and force declarer in ♥ but not ♦. Of course it will be quite double dummy as declarer is hiding a huge ♣ suit.

 

For the declarer side, one should immediately turns to develop his side trick once finding that trump break 4-1. Drawing the 3rd round trumps will be fatal.

 

 

 

For the second deal EW should aim for 7♦ if ♠ behaves. And one should guard the possible 4-1 breaks in ♠ when playing 6NT, by playing small to J first - i.e. crossing to dummy in the 2nd trick.

Great.
