Rebel century lost against boris malisov(2350 rating)
I resigned at move 21 and did not play the last move of the game.

I do not understand the reason for the move 12...gxf5
I thought during the game that maybe I put
Rebel at a low level or maybe I had the wrong personality or maybe it is a bug
in Rebel Century but I found that Rebel1.2a also does the same blunder.

I found also that many top programs including Crafty17.10 do the same
blunder(Crafty may avoid it at tournament time control but I expected computers
to avoid it from the first second and not to need some minutes to find a better
move).
I do not understand what push computers to sacrifice their king safety for no
compensation that I can see(Rebel even does not get a pawn for the move gxf5
exf5 and I think that this line is also not good for black)

People told me after the game that Rebel Century played like 1700 player.

The relevant position:
r2q1rk1/p3ppbp/2bp1np1/2p2P2/1p2P2Q/3P1N2/PPP1N1PP/R1B2RK1 b - - 0 1
