Jul-29-11		et 9: Ahh...Chablis .... Seeking to impress or simply to play, the patron said to the waiter, "We'll have your finest 'house' chablis ! Funny how follow through is so hard to come by in my analysis. I see the move that clearly has the most play, that is clearly the 'funnest' move, and that often detracts all objectivity.

Jul-29-11		Magic Castle: <rhickma4> if 18....Qc4 19. Na7 is mate. The key move is 18. Nb5 threatening mate, followed by the sacrifice of the white bishop with check. Sooner it will be mate by the white queen at C6. Work it out and enjoy.

Jul-29-11		LIFE Master AJ: I remember this game, it was published in several magazines of the time ... (18.Nb5! which threatens the VERY sneaky 18...QxQ/c4??; 19.NxP/a7#.)

Jul-29-11		castledweller: Nb5 . . . . a great move that Chucky no doubt simply overlooked. He must of thought he could take White's queen (and diffuse the gathering White storm) before any difficulties aroze. But Nb5 is a forcing move that does the double-duty of freezing the Black queen just long enough to serve its purpose!!

Jul-29-11		abuzic: 18. Nb5, and black loses the queen or is mated: 18...Qxc4 19.Nxa7# If 18...Bxb5 19.Bxb7+ Kxb7 (19...Kd7 20.Qxb5#) 20.Qxb5+ Ka8 (or...Kc8) 21.Qc6# If 18...Bc6 19.Nxa7+ Kd7 20.Qxe6+ Ke8 21.Qxe7# If 18...Bd6 19.Bxd6, and same threats. White castling on move 12. looks ok, he could take initiative with 12...Bd6 instead, threatening mate and then he would have the option to castle either side. It seems 13...Qd6 was a bad move, 13...Qf5 is probably better.

Jul-29-11		BiteByBits: the point is to change the move order, i saw Nb5 for the surprising mate threat, but it takes time to work out how to gain the tempo on that black Qxf4 threat, and Bxb5 that your opponent have.

Jul-29-11		howlwolf: Seemed easier than usual for Friday. You only have to see three moves deep.

Jul-29-11		swr: Quite easy for a Friday.

Jul-29-11		kevin86: I saw the "Boden" bishop there and saw that mate was in the offing.

Jul-29-11		Fusilli: <swr: Quite easy for a Friday.> First I thought I was having a great day, but on second thought you are right... I haven't gotten a Friday puzzle this fast in a long time, and I see I wasn't the only one.

Jul-29-11		Creg: I thought if the b7 pawn wasn't there that white could play Qa6 mate, but how to get rid of it? Then I realized the black king was trapped, and once you see 18.Nb5 threatening 19.Nxa7 mate, the rest is rather easy, if you've been studying your tactics all this time. 18.Nb5 Bxb5 19.Bxb7+! Kxb7 (avoiding capture does not change the outcome) 20.Qxb5+ Ka8, or Kc8 and 21.Qc6 mate.

Jul-29-11		Marmot PFL: 18 Nb5 found fairly quickly (3rd candidate)- 18...Qxc4 19 Nxa7#; or 18...Bxb5 19 Bxb7+ Kxb7 20 Qxb5+ and Qc6#. Black took too many risks here, chasing e5 a little soon (Ne7-g6 looks slower and safer) and exposing his queen on the open e-file. Q-side castling also has some well known dangers.

Jul-29-11		doubledrooks: Solved it. 19. Bxb7+ was a nice zwischenzug.

Jul-29-11		sevenseaman: What is a zwischenzug. Is it same as an intermezzo. Please define if the two represent different kinds of moves. Some are calling it the 'Boden' B? At times illiteracy hurts.

Jul-29-11		doubledrooks: <sevenseamen>: instead of playing 19. Qxb5 immediately, white plays an in-between move (19. Bxb7+). That's a zwischenzug.

Jul-29-11		LIFE Master AJ: The main line (I think) is a mate in four: 18.Nb5!, BxN/b5; 19.BxP/b7+!, KxB/b7▢; (Or 19...Kd7; 20.Qb5#) 20.Qb5+, Ka8; 21.Qc6#.

Jul-29-11		FSR: This seems very easy: 18.Nb5! Bxb5 19.Bxb7+! toasts Black.

Jul-29-11		FSR: <sevenseaman> Zwischenzug, intermezzo, and in-between move mean the same thing. As for Boden's mate, see this article, largely written by me: http://en.wikipedia.org/wiki/Boden'...

Jul-29-11		patzer2: The double attack 18. Nb5! threatens the Queen and mate on a7. This forces the reply 18...Bxb5 to set up a decisive in-between move with 19. Bxb7+! .

Jul-29-11		morfishine: <sevenseaman> Loved your Bridge story!

Jul-29-11		Eduardo Leon: Easy puzzle is easy. <18.♘b5! ♗xb5> Forced, due to the double threat of 19.♘xa7# and 19.♘xd4. <19.♗xb7+!> A nice in-between move. Because of the placement of black's very own d8 rook and bishop, the black king cannot escape the danger zone: 19...♔d7 20.♕b5#. <19...♔xb7 20.♕xb5+> And white's next move will be 21.♕c6#, regardless of what black does.

Jul-29-11		Riverbeast: Oleg Demolishin!

Jul-29-11		sevenseaman: Thanks <FSR>. Quite a feast in your wiki article on Boden's mate. Very well illustrated. So the defining characteristic is crossing diagonals. Aah, emancipating clarity! <doubledrooks> I always thought a zwischenzug/an intermezzo/ an in-between move/a waiting move were always a time-marking move. This is the first I've noticed where it is a debilitating, crucial check and still remains a time-marking move. Thanks. <morf> You are a dear! I am concerned when you give the puzzle a cursory before rushing to work. I really hope you find a way of staring at it for at least 5 minutes. If still blank, carry it in your head; it helps. I am resolved on half an hour irrespective of the day of the week. (But to be fair to you, I have time.) My love for the game impels me to give it my undivided attention. I do feel fidgety after 5 minutes and outright restive after 10; but dedication urges discipline.

Jul-29-11		LIFE Master AJ: GM Oleg M. Romanishin (2560) - GM Vassily Ivanchuk (2475) [C02] URS-ch FL54; Irkutsk, (USSR) / 1986. [A.J. Goldsby I] A nice miniature, this contest provides our POTD for Friday; July 29th, 2011. 1.e4 e6; 2.d4 d5; 3.e5, The Advance variation ... of the French Defence. [ More common is the Tarrasch, (3.Nd2); or 3.Nc3 Bb4; 4.e5 c5; 5.a3 Bxc3+; 6.bxc3 Ne7; which leads to the main lines of the Winawer. (See Opening Explorer.) ] 3...c5; 4.c3 Nc6; 5.Nf3 Bd7; This is one of Black's favored choices today; also played in the top choice of 5...Qb6. *** [ For the continuation of: 5...Qb6; 6.Be2 cxd4; 7.cxd4 Nh6; (play) [ See MCO-15, page # 203; beginning with column # 01; and all applicable notes. ] The main line (from MCO) seems to stem from the following contest: Nunn - Schmittdiel; Dortmund, GER / 1991. (Nunn vs Schmittdiel, 1991) ] * 6.Be2 f6!?; This leads to many lines (in the center of the board) getting opened early in the game, the tried and true system here is 6...Qb6. * [ According to the "Power-Book" ... Black would do better to play: >/= 6...Nge7; 7.0-0, Â² (" ") when White only has a small advantage in this position. GM J. Timman (2650) - GM M. Gurevich (2643); [C02] / Bundesliga 99-00 / GER; (R# 4.4) / 1999. (White won, 1-0 in 36 moves.) (I did not find the above quoted game in the CG database.) ] *** 7.0-0 fxe5; 8.Nxe5 Nxe5; 9.dxe5 Qc7; 10.c4, White sacrifices a button for a little play here. [ Playable was: 10.Re1, ] Play (now) assumes a sharp and somewhat forcing nature ... 10...Qxe5; 11.Bh5+ g6; 12.Bf3 0-0-0; 13.Re1 Qd6!?; This central square looks OK for the Black Queen, although >/= 13...Qf5; also looked like a good candidate move for Black. There is very little experience in these lines for Black, there are only a handful of games in the CB (on-line) database - from this particular position. 14.Nc3 dxc4?!; For Black to open more files and diagonals (in this situation) does not seem like a good idea to me. (Fritz - and a few other engines - prefer the play of 14...d5-d4; here for Black.) 15.Qe2 Nf6!?; 16.Qxc4 Be7; Even though Black is a Pawn up in this position, many of the strong chess engines see a large edge ( ) here for White. 17.Bf4! Qd4?; (Maybe - '??') Black blunders ... although it was easy to miss White's next move. (Many of our readers did!) click for larger view We now have reached the position for today's daily chess puzzle. [ Best was: >/= 17...Qa6T; ("▢") although after an exchange of Queens on a6; Black's Pawn structure has more holes than Swiss cheese. ] Now it is: "White to move and win." 18.Nb5! Bxb5; 19.Bxb7+!, Black resigns. (1-0) The end would come after: 19...KxB/b7; (Or 19 ...Kd7; 20.QxB/b5#.) 20.QxB/b5+, ...Ka8▢; 21.Qc6#. (Or 20...Qc8; 21.Qc6#.) A nice effort by Romanishin, although a young Ivanchuk certainly did not play (anywhere near) the best lines in this game.

Jul-29-11		sevenseaman: < Riverbeast: Oleg Demolishin!> An inspired thought! Very apt to this game. One rarely sees Chucky dissected so thoroughly. At the time Chucky was only 17 and a bit lower in the ranking rating.
