White's problem is the f3-Pawn, which is vulnerable to a combined attack by the Black Queen and Knight, threatening perpetual check on the White King. This is why you see the evaluation '13.b4 (0.00)', indicating equality. Black's position is saved by a tactical resource. <br /><br />While I don't believe this is a resounding success for the SP from Black's point of view, it is still a draw. White has to vary earlier to achieve more than equality. - MarkMark Weekshttps://www.blogger.com/profile/10101044127493771263noreply@blogger.comtag:blogger.com,1999:blog-6011690536420808420.post-85908800419711101372014-11-22T06:20:45.081+01:002014-11-22T06:20:45.081+01:00GeneM - Thanks for pointing out the error in the d...GeneM - Thanks for pointing out the error in the diagram.

On a 2014/Nov/14 ChessBase.com article I commented about this problem regarding the PGN view that ChessBase webpages use.

Despite what looks like a weak position for black namely:<br /><br />weak king safety<br />passive queen<br />disconnected rooks<br />exposed king<br />weakness on the light squares<br /><br />white has:<br />the bishop pair<br />pawn majority in the centre<br />safer king<br />centralised queen<br /><br />I put the position through Stockfish-5 and analysed it to depth 30. Stockfish evaluates it at exactly 0.00 with its top moves being:<br />13.b4 (0.00)<br />13.Qe2 (-0.17)<br />13 f4 (-0.17)<br /><br />If I were to play this position for white today, I would play:<br />12.gxf3 f5 then<br />13.b4 to weaken black's control of the centre. Black would be on the back foot because white has a pawn majority in the centre and both bishops in a position that should open up.<br /><br />Black looks to be in some trouble.<br /><br />Hope you are keeping well Mark!<br />Chow HarryHarryOhttps://www.blogger.com/profile/15971894954907592580noreply@blogger.com
