Is it really so unreasonable to introduce some bias into the simulations so that West is made less likely to have the ♠K after trick 2?

3 people misdescribed their hand by superaccepting with 4♠ (showing a doubleton heart). They all made...

(Um, I don't know why the play isn't being shown but GIB N ran the ♠10 and it held, then played ♠ to the ace.)

The faulty play is shown, just press the next button

He made another thread in BBO support saying he had to cut the code short (notice there's no explanation for 5H and 6S)

Right, I reedited and got it working.

Maybe Fred should get someone to program in basic hand combinations like BBO does every month in Bridge World or even better csrd play combinations from Encyclopedia of bridge, this one seems pretty basic.

GIB doesn't work like that, it doesn't have any goals like "I need 4 tricks from this suit" or whatever. It works by dealing out cards in accordance with what is known and solving that as a double dummy problem, several times over, and checking which card was successful most often. The key point here is "what is known" - after trick 2, the simulation should not be dealing the ♠K to West very often anymore.
