Aug-28-07		ChessCompFan: can someone please tell me how to beat Little ChessPartner?

Aug-29-07		Gilmoy: 15.Qd4 16.Bd3 is a head-scratcher -- White's Q gets nigh-trapped in front of its minor pieces, and Black kicks her around for about 5 free tempi, plus the fork threat 23.b3? Nc3+. White dies on the Q-side without getting in a single K-side pawn push.

Sep-04-07		notyetagm: Wow, what a great finish by Navara, 26 ... a4-a1!. The tactical point is that the Black c3-queen =already= controls the a1-square because the a1-square is on one of the diagonals of the Black queen and the Black piece which masks the Black queen on this line, the Black b2-knight, can get off of this line with a <GAIN OF TIME> by <CHECKING> the White c1-king (... b2-d3+). That is, because the Black b2-knight which masks the Black c3-queen from directly controlling the a1-square can move off of this line with a <GAIN OF TIME> (... b2-d3+), it is as if the line from c3 to a1 is =already= open so that the Black c3-queen =already= controls this square. Hence Black does not have one attacker on the a1-square (Black a4-rook) but two(!) attackers on this square (Black a4-rook =and= c3-queen) so that the a1-square is not <LOOSE> but actually <EN PRISE>. Navara is really tactically sharp.

Sep-04-07		notyetagm: <ChessCompFan: can someone please tell me how to beat Little ChessPartner?> Use Rybka. :-)

Sep-04-07		notyetagm: Wow, more great tactics from Navara. Here 25 d5-a2 puts the Black b2-knight <EN PRISE>. Navara does not then retreat the threatened knight to safety but instead he defends it =tactically= with 25 ... c4-a4!. The tactical point is that the Black b2-knight is now =taboo= since taking it with 26 a2xb2?? allows a mate in 5 based on the tactical motif <X-RAY> 26 ... a4-a1+! 27 b2-b1 (27 b2xa1 c3xa1#) 27 ... a1xb1+ 28 c1xb1 f8-b8+ 29 d3-b5 b8xb5+ 30 b1-c1 (30 b1-a2 c3-b2#) 30 ... c3-a1#.
