This is a real hand and just for fun so no names are used except you are playing R. Hamman's team. I understand both tables failed to beat this one. You sit in the defensive chair of a Grand Master at one table and a Diamond Master at the other.
Trick one=KC. A, 2, 3 standard carding
Trick two=AH, 9, Q, 3
Trick three=2H, KH, 3S ruff, 5H
Trick four=KD, 9, 3, 6
Trick five=4D=? your play?
If you ruff at trick five assume partner high lows in D.
trick 6 you return h and pard pitches a club as declarer ruffs.
trick 7 he leads another small D? your play again.
edit Hint:
1) What is your plan to beat this one? I could not find one, it seemed hopeless so:
2) Out of desperation I fell back and followed 2 general defensive rules that we have all seen in books. Good Luck.
