One does not often willingly exchange queens into a simple endgame a pawn behind when one is hoping for victory, but that is what Jonathan Rowson did in today's game. Played earlier this month in Tallinn, Estonia, it was one of the games that brought Rowson the silver medal in the European Junior Championship. I do not know how much he had calculated when playing 34.f5, but it resulted in the loss of a pawn - and the eventual win of the game.

Both players seemed to become a little confused in the opening. When White plays 7.N5c3 instead of 7.N1c3, the idea is usually to develop the other knight to d2 rather than a3. By the time he settled for 12.Na3, he had already played the cumbersome plan of Re1 and Bf1, slowing down his K-side play. When Black then went in for the strange 12...Nb4?! it gave White a chance to bring his knight back via b5 to d4. When Black's knight came back to c6, it was difficult to work out who had lost more time and whether it had been worth it.

Black's 24...d5 changed the complexion of the game but Rowson's 34.f5! seized the initiative. Black won a pawn, but the white pawn at f6 forced Black's king on a long trek to rejoin the game. The black e-pawn was bound to fall, and after that, the endgame was won for White, who played the final king and pawn endgame very neatly.
