I was one of a few who received a poor MP score due to the North bot leading Spades at trick 8 after winning with the King
Other tables with maybe different bidding (eg 2 spades or pass rather than 1 spade) made one or two extra tricks
Double dummy South didn't make a defensive error - but obviously I did something to throw the North bot
I have been trying to look at all the other hands and see the difference but nothing obvious
