I won against a 1000!!! (im 700 elo)

LETS GO!!!

I did use game review, but that algorithm sucks.

So i came to forums.

How can i improve?

I play as black.

good job

bro must be ashamed

fr

still can't believe a 1000 hung mate in one

That’s awesome! Congratulations on the win! Beating a player with a higher Elo is a great achievement and a testament to your skills. How did the match go? Any memorable moments?

Nice spot on the queen pin, but were you seeing those pin tactics when you played Nf6? I think you play quite riskily putting pieces in the line of fire of pawns. The engine sees Bd6 as a mistake because you're giving the opponent multiple ways to attack your pieces with defended pawns, now and in the future after trades which will give your opponent momentum to develop.
But apart from the opening, good job not blundering, trading down and setting up the mate. Monopolising on enemy blunders with solid play like that will easily climb your elo

One improvement would be not to play stuff like bd6 in the opening that locks in your other bishop and blocks a central pawn (the first time that bishop moves is on move 19... the opening is long over by then).
