Today I’m returning to a subject I’ve covered a number of times in the past: passed pawns. Passed pawns are a crucial aspect of chess and your attitude to them can have a profound effect on how you play and, in particular, your opening choices. To explore this topic, I look at a game played by Vasilios Kotronias, in which he was overwhelmed by an absolute pawn avalanche. The final phase is extraordinary and somewhat reminiscent of the famous game McDonnell versus De La Bourdonnais.
