Over the long July 4th weekend, Abe played in the FIDE Continental America’s Amateur Chess Championship. He had a so-so performance with an even score (3.5 out 7).
After the first day’s games (he scored 0.5 point out of 2), on the way home, he said he’s winning in the second game, then he made a mistake to take the opponent’s strong piece: a rook in stead of a pawn. After that, Abe said it’s a drawn position. Looked surprised, I asked him “Played like a Child?”
I felt Abe’s not offended since Abe then mentioned Magnus Carsen commented his own lost game to Garry Kasparov “I played like a child” when Magnus was 13.
“I am still a child” Abe added.
Two days later, I have the computer analyzed the game. I asked Abe to have a look at the analysis result: The ending’s not a drawn position, he still has chance to win.
“Oh, the Opposition!” Abe exclaimed after looking at the 1st move.
I remember we watched a video together about pawn endgame (including the technique of Opposition) not long ago.
