13...b6 [Black didn't need to give up the pawn as the c5 pawn is as good as dead unless White has a self-destructive desire to give his king lots of breathing room. 13...Bg4 developing the bishop, and freeing the c8 square for either queen or rook was better. 14.Be2 Bh5 with the idea of Bg6. If 15.Nxd4 exd4 16.Bxh5 g5 17.Bxg5 hxg5 18.Bf3 Qd7 and Black is ok.]

26...Nxa3+? It is hard to explain this desperado move, other than last-round nerves.
