Aug-10-11		Nightsurfer: The move 8.Nd2? ... - maybe White has wrongly assumed that Black Ne4 was pinned by White Bg2?! - has been the basic strategic error. By accepting the doubled pawns c3+c4 plus the exchange of Bishops on the diagonal a8/h1 (and thus creating the dangerous weakness of the White squares in the castle of White King) White has virtually invited his opponent to come and get him. The same mistake - 8.Nd2? ... - has been committed 19 years later in the parallel case S Amiri vs R Rezaei, 1992 Therefore it has not been by chance that both White King in this game here <B Koester vs R Gralla, Elmshorn 1973 > and White King in S Amiri vs R Rezaei, 1992 , the two of them have met their fate after having been forced to flee the smoldering ruins of their castle: White King here on g4, in <B Koester vs R Gralla, Elmshorn 1973 >, White King in S Amiri vs R Rezaei, 1992 just one step away on h5! A strange coincidence! Instead of 8.Nd2? ..., White should better have played 8.Qc2 ..., of course, please compare Deep Fritz vs Kramnik, 2002 ... DEEP FRITZ can not be wrong.

Aug-10-11		Nightsurfer: The early foray by Black Knight right into the center, namely 6. ... Ne4! and thus boldly seeking confrontation with White Nc3, may look premature, but the move has been applied by great masters in the past too, please compare Opocensky vs Keres, 1939 or S Bernstein vs Yanofsky, 1942 or P Vaitonis vs Najdorf, 1935 or last not least Teichmann vs Saemisch, 1923 Black cavalry in the center has got new support during the last decade of the 20th century, one example is S Amiri vs R Rezaei, 1992 , and at the beginning of the 3rd millennium, please replay Deep Fritz vs Kramnik, 2002 (though in the latter case the Swing of Horse has been executed one move later, namely with 7. ... Ne4 after the foregoing 6.0-0 0-0 7.Nc3 ...).

Feb-13-13		chaimzvi10: white could win if he played 22.bh6 instead of be3. if 22...qxb 23.rxr if 22..,qf7 23.qxq if 22...qe8 23.rxr g6xr 24.re1

Mar-10-13		Nightsurfer: <chaimzvi10>: White overlooked <22.Bh6! ...>, for sure!

Mar-10-13		Nightsurfer: <chaimzvi10>: After the eventual <22.Bh6! ...>, Black should have tried <22. ... Qf6?!?!?> - thus ending up with a horrible position ... :-( ...

Sep-24-14		Nightsurfer: Chess is a war game, therefore you should look at the board like a military commander. And it is always a bad idea to let your elite troops go astray whilst the enemy attacks the HQ - just have a look at the turning point of this game after <26.Qc6 ...>, please see the diagram as follows: click for larger view White Queen has got lost on <c6>, and White Knight on <b3> can't help White King either. That's why nobody should be surprised that <26.... Ng4> is the winning move, please check out the diagram as follows: click for larger view The game is over, more or less, after the White move <27.Rfe1 ...>, please see the diagram as follows: click for larger view (But 27.Rxf5 ... would not have helped either because of 27.... Re2+!! 28.Kf1! ... - A. 28.Kg1 Qxf5 29.Rf1 Re1! 30.Rxe1 Qf2+ 31.Kh1 Qxh2# / B. 28.Kg1 Qxf5 29.Qa8+ Kg7 30.Rf1 Re1! 31.Rxe1 Qf2+ 32.Kh1 Qxh2# / C. 28.Kh3 Rxh2+! 29.Kxg4 Qxf5# / D. 28.Kf3 Rf2+! 29.Ke4 Qxf5+ 30.Kd4 Qe5+ 31.Kd3 Qe3# / E. 28.Kf3 Rf2+! 29.Kxg4 Qxf5+ 30.Kh4 Rxh2# - 28. ... Qxf5+! 29.Kxe2 Qf2+, and now either 30.Kd3 Ne5+ 31.Ke4 Qf3+! 32.Kd4 Qd3# or 30.Kd1 Ne3+ 31.Kc1 Qc2#) After White has lost control of the f-line, the execution proceeds as follows: <27.... Rf2+ 28.Kg1! ...> - in case of 28.Kh3 ... would follow 28.... Rxh2+! 29.Kxg4 Qf5# - , and now Black sacrifices one Rook since he does not want to lose the momentum: <28. ...Rg2+!!>. Just have a look at the diagram as follows: click for larger view White has to take Black's Desperado Rook: <29.Kxg2 ...> But the grim consequences are: <29.... Qf2+ 30.Kh3 Qxh2+! 31.Kxg4 Qh5+> Please have a look at the final diagram as follows: click for larger view And White stops fighting - <32.resigns> - because of the threat 32.Kf4 ... and 32.... Qf5# , and that would have been too much for him, of course.
