Both players blundered badly on move 26.

Both players blundered badly on move 26.

I doubt they are blunders. Finding such moves and playing them are tense.

Yes, typical human errors.

Correct is 26. Qxd3.

26. Qxa8 loses the game, if Black plays 26... Nxf2.

Round 4 vs Gupta :

[d]r2r2k1/1q3ppp/4p3/N1n5/Rb6/BPp1P1P1/5P1P/2Q2RK1 b - - 0 21

It seems to me that Firouzja needs to improve his technique.
