Jul-22-12		Memethecat: Oh well!! close, but no cigar. 25.Nc5 is a stunning move, I'd need a brain transplant to have seen this.

Jul-22-12		sevenseaman: Interesting line Rodriguez followed. 25. Nc5 is way over my head. His line is drastically different from mine. Well that's life. On Sundays an Saturdays chances of hitting the jackpot are generally low.

Jul-22-12		Winner12: Nc5 !!

Jul-22-12		ventricule: Analysis here : http://www.uschess.org/cc/dunne/apr...

Jul-22-12		al wazir: <perfidious>: That must be what I meant to post. Thanks.

Jul-22-12		ounos: Come on. There is no way white saw 25. Nc5! when he played 22. Rxf6 (but let me check if he was Tal... nope, wasn't)

Jul-22-12		bachbeet: I thought the rook taking f6 was the right move. Can't say that I saw all 14 moves after that though. I'll give myself partial credit.

Jul-22-12		gars: <LTJ> Congratulations on your tactical prowess! A modest Monday, Tuesday and (sometimes) Wednesday solver I praise all the stronger players.

Jul-22-12		Jimfromprovidence: I stumbled onto another benefit of playing 25 Nc5. Say black plays 25...Bxf6, below, (thinking 26 Qf5 Bg7, with a pretty even game). click for larger view But white has 26 Bxf6, which is a forced mate. click for larger view The point is if black moves his f rook to give his king some escape squares, the knight on c5 cuts off any escape as it covers e7. One such line is 26...Rfd8 27 Qg2+ Kf8 28 Qg7+, etc. click for larger view

Jul-22-12		scormus: <LTJ ... 0.90> I think youre being hard on yourself, and I wouldn't want to feel responsible for your not getting 7/7. But yes, Rh6 is a very effective reply to ... Kh1, also after 23 ... Kh8 which I was wrestling with earlier. According to my engine its # in 9. Thanks <CG> after 5 rather soft weekdays we had 2 real goodies this weekend. Today my Rybka had a lot of trouble deciding that W was even winning. After 22 Bxf6 it had to search 1.6 Mnodes before finding a winning line for W, evalled about +2.9.

Jul-22-12		Once: click for larger view White to play: 25: ? CG's theme this week has been about forcing your opponent to self-block his pieces. In this position, white wants to play Qf5 with the idea (if black lets him) to play Rh6 and Qxh7#. But if he plays 25. Qf5 straight away he has to contend with 25...Qc8 offering a trade of queens. Hence the quite brilliant 25. Nc5!! click for larger view Now if 25...Qxc5 white uncorks the g file with gain of time by playing 26. Be3. And all manner of nasty things are going to happen in the vicinity of g7 and h7 - eg 26...Qc8? (too late!) 27. Rg1+ Kh8 28. Qxh7+ Kxh7 29. Rh6# So black has to accept that the c file will remain closed, either by the pesky white knight or by his own pawn after 25...dxc5. Which means that the black queen can't easily get to c8. And lo we are back to our theme of forcing the opponent to block his own pieces. I didn't get it. The first moves, yes, but not the sublime 25. Nc5. The only slight negative was that this was a cc game so the white player would have had more time than normal to work out the variations. BTW ... it's my birthday. 2 years shy of my half century.

Jul-22-12		Pedro Fernandez: I don't think the only move to win was 22.Rxf6 nor much less all black moves were forced. Indeed Black lose with other moves different to 22.Rxf6. For sure Rodriguez didn't know in advance all the moves from 22. to 36.

Jul-22-12		Pedro Fernandez: As far 25.Nc5 <once> is natural not only avoiding the check in e4 but the most important: avoiding Black Queen may defends her King in g6 and that's Rodriguez worth in this game as I think he saw this move. So you are right <once>.

Jul-22-12		tivrfoa: <Once> Thank you for post. It helped me understand. =)

Jul-22-12		LoveThatJoker: <gars> Thanks, Gus! I appreciate your kind words. I came really close to finishing the week with 7/7, but I missed finding the best continuation in one important sub-variation today. I hope to do better next time! LTJ

Jul-22-12		LoveThatJoker: <scormus> Thanks for saying what you said in your last post, man! I sincerely appreciate it. I was wrong in going in for 22...Kh8 23. Qh6?. I appreciate that you brought the best continuation into light as after 22...Kh8 (or 23...Kh8 for that matter), 23. Rh6! is indeed the most accurate. Now as it relates to the 7/7 score, in all honesty, man, there is no way I can give myself credit for 7/7 this week. Really 22...Kh8 23. Qh6? was an innaccuracy I could have avoided today, but did not; so, I hope I do better next time. LTJ

Jul-22-12		LoveThatJoker: <Once> Happy Birthday! LTJ

Jul-22-12		agb2002: White has a bishop and a knight for the bishop pair and a pawn. Black threatens 22... bxc3. The black castle would be weaker without the knight. This suggests, 22.Rxf6: A) 22... Bxf6 23.Bxf6 Rfb8 24.Qh6 and mate in two. B) 22... bxc3 23.Kh1 B.1) 23... cxb2 24.Rg1 B.1.a) 24... Rfb8 25.Bh6+ Kh8 26.Bg7+ Kg8 27.Qxh7+ Kxh7 28.Rh6+ Kg8 29.Rh8#. B.1.b) 24... b1=Q 25.Bc1+ Kh8 26.Qxh7+ Kxh7 27.Rh6#. B.1.c) 24... Kh8 25.Rh6 Bxg5 (25... Kg7 26.Bf6#) 26.Rxh7+ Kg8 27.Rxg5#. B.2) 23... Rfb8 24.Rg1 B.2.a) 24... Bxf6 25.Bxf6+ Kf8 26.Rg8+ Kxg8 27.Qh6 and mate in two. B.2.b) 24... Kf8 25.Bh6+ Ke8 26.Rg8+ Bf8 27.Rxf8+ Ke7 28.R6xf7#. B.3) 23... Bc8 24.Qh4 doesn't seem to stop the plan Rg1 followed by Bh6 or Rh6as in the previous lines. C) 22... Qd8 23.Qh4 bxc3 (else Nd5 keeping the material advantage) 24.Kh1 looks similar to the lines above.

Jul-22-12		andyatchess: I like move 32!

Jul-22-12		hedgeh0g: Way over my head.

Jul-22-12		amr52: i see22.♗h6is a winner and fatser than the text move , does any one have different analysis

Jul-22-12		TomOhio: Why bother with the "annonation" when the extent of it is "!" and "!!"? Not helpful.

Jul-22-12		Patriot: <amr52> I thought so too but Houdini says it loses! It's very complicated (see below). I also considered 22.Nb5 axb5 23.Rxf6 Bxf6 24.Bxf6, winning. Houdini suggests 22...Qd8 is =, which makes sense. New game - Houdini 1.5a x64, Blitz:4'+2" Microsoft click for larger view Analysis by Houdini 1.5a x64: 1.

Jul-22-12		bobstep: amr52, bh6 does not seem clear after the simple kh8, w can win exchange, but king is very exposed.
