It's weird. I seem to have chess blindness about a specific square -- for some reason, I manage to hang the b pawn to some stupid attack from across the board by the queen in EVERY GAME I PLAY.
I had a simliar experience Game 5050497 and left a
Bishop hanging on d2 - I thought I could then play Ne4
but the next day I saw a pawn on f3. Luckily my opponent
walked in a trap a few moves later.
I came home late after a night a the pub and made the blunder.
Haha, I like that -- drunkenness is a pretty good explanation.
Examples: well, two ongoing games are what come immediately to mind, so I won't post them (though I may resign one of them shortly, so I'll post it then).
