1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Nf3 Ngf6 6.Ng3 e6 7.Bd3 c5 8.c3 Be7 9.0–0 0–0 10.Qe2 b6 11.Bg5 Bb7 12.Rad1 Qc7 13.Ne4 Rad8 14.dxc5 bxc5 15.Bh4 Qb6 16.Qc2 h6 17.b3 Rfe8 18.c4 Bxe4 19.Bxe4 Bd6 20.Qe2 Qc7 21.Bg3 Bxg3 22.hxg3 a5 23.Rd2 Nb6 24.Rfd1 a4 25.Ne5 axb3 26.axb3 Rxd2 27.Rxd2 Rd8 28.Rxd8+ Qxd8 29.Bf3 Qd6 30.Qe3 Nbd7 31.Nd3 Qb6 32.b4!?
Dollah play an interesting and practical pawn sacrifiece. He probably believe his passed pawn has a better prospect then black's passed pawn on the b file . 32...cxb4 33.c5 Qc7?
This move cause black to lose a pawn. Black should have defend actively with 33...Qa5 34.c6 Nb6 35.c7 Nc8 36.Qf4 Qb6 37.Nxb4 Ne8 38.Nc6 Qxc7 and black is definitly not worse 34.c6! This passed pawn gave black a headache 34.. Nb8 35.Nxb4 Kf8 36.Qa3 Ke8 37.Qb2 Ke7 38.Nc2? A mistake. Luckily for Dolah, Udani didn't reply with the best answer. 38...Ne8 Black shoul grab the free pawn with 38...Nxc6 because the pin on the queen after 39.Qc3 didn't work because black can simply play 39...Kd7! 39.Nd4 Nd6 40.Qa3 Ke8 41.Qb2 Ke7 42.Nb5 Nxb5 43.Qxb5 f6 44.Qc5+ Kf7 45.Bh5+ g6 46.Qc2 f5 47.Bf3 h5 48.Qc3 Nd7??
A serious blunder that cause black the game. Probably Udani was in time trouble because he's usualay won't miss this kind of tactic. The correct move is to sit tight and block the c pawn. For e.g 48...Qc8 49.Kh2 Na6 50.Qd4 Nc7 49.cxd7 Qxc3 50.d8=Q black simply a piece down 50...Qe1+ 51.Kh2 Qxf2 52.Bc6 Qa2 53.Be8+ Kg7 and now Fritz annouce mate on 7 (maximum) 54.Qg5 54.Qe7+ is better but the text move still winning. 54...Kg8 1–0 black will be mate after 55.Qxg6+ Kh8 56.Bf7 Qxg2 ( a desperate housewives move !? ) 57.Kxg2 h4 58.Qh6# checkmate!
