(See http://www.chesscafe.com/text/dvoretsky99.pdf) However the analysis was later superseded so the defender is not forced to go for this 3 pawns v rook position any more.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-37675897.post-68345593575994623982013-12-28T21:49:40.496+00:002013-12-28T21:49:40.496+00:00Ok my account goes

It wouldn't be rare either as it can be a logical consequence of sacrificing pawns for a promotion.<br /><br />Table-bases are in agreement with comment 1 that Rxf7 only draws, but it would be easy to stumble into a loss playing an inferior move in the R v 3. <br /><br />If it were a match or tournament where not losing was important, Rxf7 would be the pragmatic choice. <br /><br />An actual game reaching this position was Gurevich v Glek from 2002 which was played by Gurevich accurately according to the tablebases.<br /><br />RdC<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-37675897.post-51111359354379618192013-12-27T08:31:07.039+00:002013-12-27T08:31:07.039+00:00I know what you're going to say.
