'The best-laid schemes o' mice an' men'.. Post mortems are a hilarious&humbling part of chess, the part potentially helping our game most, via catharsis. All we believed in or meant to have seen during a game, or most of it, turns out to be a fantasy. I'm playing with huge blinkers, and sometimes during the post mortem I hand them over to my playing partners or try on theirs and we are laughing. Engine consultations only add to this.
Position #1

Pamvo and Powder have just played
14. .. e7-e5
So I said 'pawn', in order to win a pawn. But the en passant opportunity would not occur to my partner Herman, who was muttering 'So, my brain instructs me to sac a bishop?' The second best pawn move
15.c4-c5
was duly chosen and we continued pawn down.
Position #2

Powder and Pamvo have just played
19. .. b7-b5
I wanted to say 'pawn' so Herman could play 20.b2-b4, but then I saw a ghost. It's a nice one, so I will explain: I was looking at
20.b2-b4
but then what I saw coming was
20. .. Qa5xa3 21.Rb1-a1 Qa3xb4 22.Re1-b1 Nf6xe4!
Proudly, responsibly I discarded b2-b4 and opted for a measly 'bishop' call. Pamvo & Powder capitalized with formidable pawn advances, and Herman had to loaf around with our bishop pair until he had enough and traded it down. Could I have surpassed my horizon, I could have found what Stockfish told me,
22.f2-f3!
preparing to trap the queen with Re1-b1 instead of not trapping it with Re1-b1 right away. It's quite amazing that we should have time to make a quiet pawn move and still trap the queen here
(analysis position after 21. .. Qa3xb4, before 22.f2-f3)






Definitely a brain thing.
