Sep-28-14  Atking: A very logical game. I know a "bochan" but this one is clearly stronger.

  Sally Simpson: This game features something that is quite rare in OTB Chess. It is what the problem/study composers call 'The Valladao Theme.' The solution must contain, castles, en passant and an under promotion.

Here there is Castles (move 24), en passant (move 11) and an under promotion (move 63 ) all in the same game.

May-14-18  ChessHigherCat: 65...Kg6 would walk into a comical mate in 1. I don't think I've ever seen that mate before.
