Old Americans

Richard suggests an interesting game between 2 decent GMs in USA seniors championship.

Jan Ehlvest blunders a piece on move 5 (!!) realising too late that 6 d4 isn’t possible then continues to find counterplay. The end of the game is unexplained but it is thought that they had agreed a draw on move 28 then realised they had to play to move 30 I think so it didn’t matter what they played. There is a massive swing in what the engine thinks of the position on moves 25-26.

All interesting stuff and shows what can be achieved.
