GIB decides to be kind and give me two bonus spade tricks for no reason!!!

The spade play was a well known gambit to avoid being endplayed.

It worked. ;)

SCNR. On the serious side now, why should East want to avoid being endplayed? This is not an endplay situation. The cards are on the table. West has shown its singletons in both black suits, East KNOWS South has all remaining black cards plus a red one, and no entry to dummy. East knows if it drops the queen, South will get all remaining tricks but the last one (and the last one also if South holds Q or A). It is easy to prove that dropping the queen is always giving away at least one trick: Keep the queen, and when South plays spades, take the queen and play spades back to South results in the same situation as in the first post plus 1 trick for EW. Okay, this is human logic, but what computer logic might have made East think dropping the queen might be a good idea or at least that it might not matter?

BTW I had a similar hand just a few weeks ago where GIB gave away a trick or two although the position of all remaining cards was known. I didn't report it at that time, perhaps I should have.

It seems play-related reports never get answered, so I'm not sure if it makes a difference :(

If the developers were ever going to look into play problems, I think http://www.bridgebas...__1#entry913710 would be the most clearcut place to start. I would so love to be able to see GIB's code - while it may be incomprehensible to most, any code is debuggable when you have a test case.
