Defenders make mistakes - including GIB

[Karert]

We all know when the game is up, when a contract is down, the number of tricks is clear. And playing in a 3-robot tourney, the quick & easy way to move onto the next hand is the claim button (on this hand, conceding one down).

 

I was playing day-one of the Weekend Survivor when this hand came along- a reasonable grand, the bidding (pre-dealt & bid hands) puts us in a small.

 

 

Odds against, West has all five trumps - even the small can't make in clubs.

 

After playing a trump, I paused to consider any remote end-play against West, how I could reduce trumps & put West on lead, but I don't think there's any options - West's trumps are too many & too high. For no good reason, I played out the hand anyway... and a silly error from GIB gave me the contract - GIB throws away a winning trump trick for no obvious reason at trick 6 - hands me the contract, and with it c.99.5% of the match points.
