Tightrope walking
A chess game can run you ragged in myriad ways, but in my experience the most exacting ingredient is neither the length of the game nor the strength of the opposition. Rather, it’s the sensation of walking a tightrope, knowing that even a minor misstep can make the difference between winning and losing. I played one such game for England at the recent Olympiad in Samarkand. Mine was the last to finish in a hard-fought match against Georgia, and I was heartened by fighting back from the brink of defeat in the early middlegame. But with less than a minute on the clock, I was struggling to fathom the position below, where the d7-pawn is useful but firmly blockaded, while the h3-pawn looks nimble. My opponent played the move which both frightened and excited me.
