I have won vs T.Kosintseva with Black pieces today. The game went in a wild way – at first, I got a promising position after a opened the center up, then I made a couple of mistakes and got myself into a lost position. She could have gained decisive advantage by playing 21.h5 instead of Qe4. Then she did some more mistakes and we got into a R+n vs R+B endgame, where I was still worse (could be losing an isolated pawn) but she decided to win two more pawns (after I have given one for counterplay) and got her Knight out of play on h8. So, I managed to win it and the game.
Tomorrow I am white against her.
