A deal (rotated 180 degrees for convenience) from yesterday's Zenith Daylong Reward (MP):

Trick 1: ♥2-♥3-♥5-♥Q
Trick 2: ♠J-♠A-♠6-♠2
Trick 3: ♥4-♥6-♥9-♠3
Trick 4: ♠T-♠5-?

Which card do you play from dummy? And why? (Opps are robots, in case you didn't know.)

west not know south has ♣A. why lead ♥ at trick 3? if west had ♠AQ5 then a ♣ ruff in dummy would promote a ♠trick. I therefore play for ♠ split 2-2 and play ♠K from dummy trick 4.

If robot west has ♠AQ5 then they are more clever defenser than me.

Yes, that was the point.

Pretty aggressive bidding by GiB(W), btw.
