Zero playouts at trick 10 #1

Closed ThorvaldAagaard closed 8 months ago

I played the default hand and reached this position image

Declarer can make the last 3 tricks, but there are no playouts, and thus no stats on the card to play

This will happen if there are no hands, that matching all constraints. I have no good solution other than removing constraints and the evaluate the trick again.

I think what is happening is that MakeMove update details (constraints) but when testing for invalid hands

The played hands are added before constraints are matched, but I haven't confirmed this,

This issue could be a result of illegal move played by a defender. The game under consideration should proceed according to the real distribution of cards, where user takes responsibility for the overall simulation.

Closing for now.
