Bill Smythe wrote: Can anybody come up with a vertically symmetric chess position in which, with best play by both sides, the second player to move wins? "Vertically symmetric" means that, for example, if there is a white knight on f3, then there is a black knight on f6. Bill Smythe Yes. White King g1, pawns f6,h6. Black King h8, pawns f3,h3. (But you knew that already.) Much harder puzzle: Same task but you're not allowed to use any pawns. NDE |

I like the way if the white king just moves one to the left, the pushing pawn creates a position where he can't move back to either of the G squares. -- |
