you duck the first trick, E winning with the J. He returns the club 5 to the Q and A. Now, the club J (S10) 9 and K. You play diamonds, starting with the K. E has 4 to the J. On the run of the first 4 diamonds, W discards S9, C 6, C4, and S8. He then discards ht 8 on the S A (E playing the 6). On the last D, E discards Ht 6 and W the club 2. How do you play the hearts and why? The lead is in dummy:

Playing West for the Queen of hearts seems right for the reasons you give.

I would not have played A, however.

When West shows out on the first diamond, you can be pretty sure of his 3=4=0=6 or 4=3=0=6 shape. He is favorite to hold the Q but may overcall without it.

East's heart discard is bad play, he should hold on to his hearts whatever he holds. Would you have played the hearts as you did without his discard? You should, but that risks going down if he started with Qx.

Playing for the Q with West before cashing A will get you the same 11 tricks if you are right, but assures of 10 tricks if you are wrong (East has no club left!).

So while with the discards given you can be sure of 11 tricks, you couldn't be sure to reach that situation.

(If North's hearts were A1074, your line of play is best as you need to squeeze West down to three hearts for 11 tricks!)

Let's see. After 9 tricks E and W have each discarded one heart. We assume W started with 6 clubs since bidding 3C when 5-5 in hearts and clubs would be very odd. Only one club is still out.

W has shown out of spades and both are out of diamonds.

So: After trick 9 W holds 3 hearts and 1 club, E has 3 spades and one heart. We start with a low heart from the table. If for some reason E has come down to the stiff Q we will know what to do, and if, as expected, E follows with a low spot we also know what to do.

As noted, the defense has been helpful. W might have tossed that club 2 on the last diamond, saving his spade 8, Then if declarer next plays the spade A, W follows suit. Declarer then knows that W started with 7 cards in the majors, 4 of one major and 3 of the other, but he has at least a little more to think about. And, also as noted, E could hold on to both heart spots. He knows they are spots, but declarer doesn't.

E was Challenges -GIB, and that's a typical GIB play.

There is a fundamental deficiency in GIB "logic" where GIB assumes that declarer can't misguess a 2 way finesse, or fail to drop an offside honor. The result of this logic is that GIB can randomly play a card that gives away a trick or more.
