I'm not convinced chess.com cheat detection algorithms are robust enough to catch the players who only use the engine sparingly to get themselves out of a jam... and I think that is going on A LOT among people in the 1000 range.
It’s ridiculously easy to cheese people in the endgame. In February I was playing in a tournament against this 1900 who missed many forced checkmates and went into an endgame with about a few minutes left on his clock, also up a good piece.
All i had to do was make him worried enough about my passed pawn, and then I traded rooks off and took his last pawn with my knight... so he had a bishop and knight vs a lone king with six seconds left, so a draw was agreed.
I think a lot of ppl who concentrate on blitz in particular don’t know basic endgames.
Probably true... that would be strange though since dragging a worse position out into the endgame is a common tactic to flag your opponent, and good endgame skills are needed...
But maybe I’m the only one who went through silmans endgame course with the intention of playing faster in the endgame.
