Nice play in the slam. The reason you didn't score better is tht if you played spade to queen, cash ace and exit with a spade, as many did, West switches to KD!!! I agree with you that the Funbridge bot is a better defender than GIB.
I took the double finesse and went down. The double finesse works 25% of the 3-2 breaks (KJ onside), plus 50% (D finesse working) of 50% (one spade honor onside) of the remaining 3-2 breaks, plus 50% (KD onside) of 25% (KJ onside) of the 4-1 breaks. I make that 37.5% Finessing for the king first needs a 3-2 spade break, I think, or stiff jack offside to keep trump losers to one. If KS is onside, then we need either clubs 4-3 (62%) or KD onside (50%), so 34% x (62% + (38% x 50%)) = 27.5% If KS is offside and they return a heart, we need JS and KD onside (34% x 50% x 50% = 8.5%). If there is singleton JS offside, we also need KD onside (28% x 10% x 50% = 1.4%). 27.5% + 8.5% + 1.4% = 37.4%, so pretty much identical (but better if they do not return a heart when in with a spade trick). No doubt I have missed something. Also, wherever I have mentioned KD onside, there is a minor suit squeeze instead, but I think that is slightly worse odds than the D finesse.

Thanks - but is it better chance than the double finesse? I'm not sure of the percentages.

is a spade to ace better just in case singleton king offside then u can use long clubs as a force
my entries are too bad to do that.
