Were redundant choices culled? No point in tracking all variations of pawn > queen/rook/bishop when one includes the moves of the others.

- tromp 5y agoThere is sometimes a point when you need to avoid giving stalement, like in the famous Savedraa study [1] or the vastly more intricate Babson task [2].

- CrazyStat 5y agoSometimes the queen having both rook and bishop moves is a liability. There are positions (real positions from real games, not merely hypothetical ones) where promoting to a queen results in immediate stalemate, while promoting to a rook wins the game. So those choices are not redundant.
