Why the heck did my opponent resign?!
bc he is dead lost
I don't understand. How is he dead lost when he can just grab my queen?
Either he's at school and his teacher used whatever his teacher uses to see computer screens and trolled the kid or told him to get off, or he's a pity who can't play chess, or he's a person who got bored, I usually offer a draw or repetition, if I get bored.
Your opponent under-used or abused information during or before the game.
You had enough power to make some dynamic moves and win there, even if black was better at resignation.
Ba4 Re7 and Rxb6
Or Ba4 Ra8, Bc6 and then Rxe5 (or Ba4 Ra8, Bc6 Bc3, Rc1 Bd2, Rc2)
Black is then down either a Bishop or two pawns.
If Black goes down the two pawns and trades off both sets of rooks (for the opposite colored squares bishop ending) then Black could try to hold it but it would be a long arduous endgame.
I feel that one of these applies.
- He could feel unable to play without a queen (some players do fear losing their queens, but I have not checked your opponent's past games yet to see if this is the case)
- He forgot that the Black pawn on a7 can recapture the queen, and instead panicked into thinking that the queen was lost entirely. I have previously resigned in positions where I overlooked that a piece was actually defending one of my "lost" pieces.
maybe they saw you take the queen instantly and got scared that they might have blundered it or maybe they saw no way to stop your passed pawn
