Around move 25 white has the edge, but the sacrifice could still be considered correct if white had the edge before 14...Rxf3.<br /><br />White wants to trade rooks, the best way to do that is to activate one of them so black has to trade it off. The closer black's king gets to the centre, the easier for black to ignore the white rooks. Maybe 25.Rxe6 Rxd4 26.Rc1 Bc6 27.Rc2 (just waiting for a better moment for Rxe6). Probably a draw but better than what happened.<br /><br />I thought the point of the sac was the further sac 15...e5!?an ordinary chessplayernoreply@blogger.comtag:blogger.com,1999:blog-37675897.post-9790979448578088052015-01-14T21:23:05.977+00:002015-01-14T21:23:05.977+00:00Thanks.Thanks.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-37675897.post-9294599146122351412015-01-14T19:20:08.267+00:002015-01-14T19:20:08.267+00:00Have to say I'm not fully convinced by this sa...Have to say I'm not fully convinced by this sac - surely Black can't be better eg after 25...

An exchange sac obviously makes the game less standard and in consequence - I suspect, anyway - harder for the lower-rated chesser.Jonathan Bhttps://www.blogger.com/profile/00293162543015231439noreply@blogger.comtag:blogger.com,1999:blog-37675897.post-38112339816695124122015-01-14T10:21:51.639+00:002015-01-14T10:21:51.639+00:00Don Mason is a player who knows the French well an...Don Mason is a player who knows the French well and the idea of Rxf3 is common enough in the Tarrasch. It's as much a trademark of the opening as Rxc3 in the Dragon.<br /><br /><br /> In the precise position I could only find one previous example from Austria last May ( source - collected TWIC for 2014). It's also analysed in the chessbase online database. <br /><br />Engines will vary on their assessment of the sacrifice. Even where they don't think it is the best move, they think of it of a sacrifice of the equivalent of a third to half a pawn, rather than the two pawns of Rook=5,Knight=3 .<br /><br />RdCAnonymousnoreply@blogger.com
