Fear

That I had previously lost all four games against this opponent may have contributed to my error at the end.

White to move

In a game 10 with three minutes remaining, it took me thirty seconds to find the only move that doesn't lose.

61.Re3+ Bxe3??

61...Kxe3 62.Kxg2 draws

62.f8Q+ Bf8 63.Qxf4??=

Either 63.Qa8+ or 63.Qa3+ would have won.

63...Kxf4 64.Kxg2

We played until Black captured my last pawn.

I used one second each for my moves after 61.Re3+. When I have three minutes remaining, there is no need to rush moves towards a draw.
