Meier ended up in a lost position straight out of book, almost like he intended to throw the game, the engines already showed +2 or better on virtually every candidate move for white, but Keymer played very fast and failed to convert it yet again. How many chances does he need? Well, apparently the answer is two, because Meier blundered to lose the game in study like fashion. Keymer didn’t miss it and this time he made it into the endgame-books as the winner. Was the win deserved? It doesn’t matter.
Play it safe!
