2010 ANU Open - Round 3 Upset

The first big upset of the 2010 ANU Open occured in Round 3. 4th seed IM Andras Toth defeated top seed GM Zong Yuan Zhao with the black pieces. Zhao had the initiative for most of the game but Toth kept his position together and as Zhao ran short of time, Toth gained the advantage. The game ended when Zhao lost on time in a worse position.

White cannot take the b3 pawn once black plays axb3 on the next move. There is then black penetration via Rg8-c8 and then a rook into c2.
