Play:
West leads Queen of Hearts. Guess what happens. Okay, it’s pretty obvious that I wash the trumps.
After Trick 5,
N KJT874S 9H 6C
E AQ653S K6H QD
S T7H 6D KJT87C
W 92S J84H J95D
Trick 6-7:
KS 3S 7H 2S
JS 6S TH 9S
Note how East misplays here by allowing my King and Jack to score. (Has East took either, I would only score around 11 tricks, missing on my hearts.) It’s also a luck that both Ace and Queen of Spades are in East. That basically secures the grand slam.

Moral: Luck plays like 10% in a Bridge game.

Problem: Given perfect knowledge of the hands as above to everyone playing, but everyone plays perfectly, determine whether the contract is met or not. Additionally, determine the game play.
