The recently finished FIDE Grand Swiss had a lot of interesting games. I happened to be present in Riga for several rounds and I witnessed a few of them.
I was in the playing hall when the following two rook endgames were played. I had my impressions while the games were in progress and I will share them in the comments. As usual when we use our brains, my impressions were much more cautious than the definite verdicts of the engine.
The first example was from the women’s event.
The second example was from the same round, but in the open section.
The third example was the one I noticed once I left Riga. It was a game that was crucial for the eventual winner, as he managed to win from a drawn position.
I found these endgames quite instructive. Perhaps a bit comforting is that even the best players mess them up, as with the physically demanding time controls it is more difficult to keep the concentration until the end and as we know, who errs the last is what matters.
