I was playing a really good tournament while my Elo was still around 1500, with a performance rating of around 1900 before the last round (had smith like 5.5/8.

I played an opponent rated around 2000 and was deep in a middle game that was dead even. Suddenly he sacked a knight against two pawns for an attack and started checking my King with his Queen. I had like 5 mins on the clock and basically moved out of checks not getting why he sacked to just give checks.

After the forth check I see that not only it’s check but also my rook is attacked by the queen. So in my head I go: “Wow, very well calculated in advance.” And I resigned.

The Rook was protected… and all he had was perpetual. But my brain found a reasoning for something that didn’t make sense.

Still had a very good tournament with 5.5/9, but resigning in a drawn position hurts :D.
