These games can be downloaded from the CC Resource Center. As I was playing over these games these endgame positions were noticable in that the moves played should be avoided. See how your programs handle these. Would they play the same moves? It looks like better moves are there, some more obvious than others. For example, Nimzo99a's Kd4 against Shredder is baffling. There must be some explanation for that. Also Junior's lack of Knight promotion is punished in its Re8 move vs. Nimzo99a. A tougher one is Genius' Kg2 vs. Shredder3. The only move is Bxd4 which straightens out black's pawns but favourably plugs up an entry point for black's King. Some positions are more interesting than others. Some include knowledge of endgame pieces that draw while others are good old pawn race themes. As always, please report any errors you find in these observations on what I think are moves to be avoided. Enjoy.
