The computer indicates equality, but in practice his position is already easier to play. 26... e7f7  27. c2b3  27... d8e8  28. a4a5  28... f4e6 [%c_effect e6;square;e6;type;Mistake;persistent;true] This is a blunder. 29. d4e3 [%c_effect e3;square;e3;type;Mistake;persistent;true] So misses his chance. 29... e6f4  30. e3d4  30... a7a6  31. d1d2  31... b8a8 With a complex position, both strategically and tactically, and with both players short on the clock, the game becomes chaotic. I feel a little embarrassed having to criticize moves in this situation, but it's my duty as an analyst to show the readers the mistakes. 32. b3a2 [%c_effect a2;square;a2;type;Inaccuracy;persistent;true] The idea is to protect the bishop and prepare c4-c5, but this is not dangerous. 32... f7e7 [%c_effect e7;square;e7;type;Inaccuracy;persistent;true] 33. a2b3
