Dec-19-03  Shadout Mapes: This game reminds me of Steinitz - Von Bardelben
Dec-19-03  northernsoul: chessgames -
Dec-19-03  JSYantiss: northernsoul, the spelling "Zuerich" is technically correct.....In the German language, this spelling would normally have an umlaut (two dots, like a colon lying on its side) over the u in "Zuerich," but since American keyboards don't have the ability to produce letters with umlauts, an "e" is acceptable to be put in place of an umlaut when needed.

Shadout Mapes, that is exactly the game I thought of too! White's rook thumbs his nose at Black's king in both that and this game.

Dec-19-03  Replic: Strange... I ran Crafty version 19.03 for a longer period of time- it picked and stuck with 20. Kxg7 the entire. Why is it my crafty seems to not be giving the same moves? Ignore the 1., that's really move 20. Also a question- how does get crafty to give an advantage to black or white sign? Or do they simply add it themselves? My crafty evaluation:
depth=16 2/3 +10.08 1. ... Kxg7 2. Ne6+ Kg8 3. Nxc7 Rac8 4. Bc4+ Kh8 5. Qg5 Nhf6 6. Qh6+ Nh7 7. Ne6 Rg8 8. Rd1 Nf6 9. Ng5 Rc7 10. Bxg8 Nxg8 11. Qxg6 Nxg5 12. Qxg5 Nodes: 923954470 NPS: 439657

  patzer2: White's 18. Rg7+! is the solution to number 4901 in Laszlo Polgar's 1994 book "Chess," and is classified as a sacrfice on g2/g7.

However, it seems to me the sacrfice to demolish pawn structure starts with 17. Rxf7+! and the combination starts with 15. Ng5!

  Phony Benoni: This game was essentially duplicated in Orest Popovych v. John N Jacobs, US Open, 1967, Black dragging it out one more move with 20...Kh8 21.Rxg6.

At least he could say he lost like a grandmaster. I wonder if Popovych knew the original game, and mentioned it to Jacobs afterward.

Nov-21-10  sevenseaman: All Black stars are wrongly configured; White has an overpowering sway.
Oct-13-16  zydeco: Must be one of the worst games of Olafsson's career. Fianchettoing the bishop seems wrong.
Jan-08-17  ughaibu: The fianchetto might not be the problem: J Penrose vs Gligoric, 1960.
Mar-02-23  Brenin: 17 Rxf7+ Kg8 (17 ... Rxf7 18 Ne6+ wins Black's Q, 17 ... Kh8 18 Rxh7+) 18 Rg7+ Kh8 19 Rxh7+ Kg8 20 Rg7+ Kh8 21 Rxg6 Nf6 22 g4 winning the N.

  Dohboy: Nice game. The Fork threat created a sort of Windmill tactic.
Mar-02-23  devere: 17 Rxf7+ Kg8 18 Rg7+ Kh8 19 Rxh7+ Kg8 20 Rg7+ Kh8 21 Ne6 Qd6 22 Qg5 +-

  agb2002: The pawn on f7 prevents Ne6+. Hence, 17.Rxf7+:

A) 17... Rxf7 18.Ne6+ wins decisive material.

B) 17... Kg8 18.Rg7+ Kh8 (18... Kxg7 19.Ne6+; 18... Nxg7 19.Qxh7#) 19.Rxh7+ Kg8 20.Rg7+ Kh8 21.Rxg6 wins (21... Ndf6 22.Be2).

C) 17... Kh8 18.Rxh7+ transposes to B.

Mar-02-23  jrredfield: I saw 17 Rxf7+ right away. Of course Black had to move Kg8 rather than Rxf7 allowing the White N fork. But it was too late anyway. Black would have been pretty close to even, at least still in the game with 15 ... Bxh6 or 15 ... Qc5+. 15 ... Nh5? was quite unfortunate.
Mar-02-23  saturn2: 17.Rxf7.... Kg8 (orherwise royal foek) 18. Ne6 covering also c5 so the queen cannot get out of the affair with a check. Then Nxf8 Kxf7 followed by g4, Rf1 Bc4 and though material is even for a while white'sattack is too strong.
Mar-02-23  mel gibson: I saw that straight away.

Stockfish 15 says:

score for White +10.89 depth 39.

Mar-02-23  saturn2: Actuall after 17...Kg8 18.Rxf8 Nxf8 is enough with a pawn up an arrack.
Mar-02-23  Schwartz: Nxh7 Rh8 Qe7. 17. Nxh7 Qd8 18. Qxd8 Rfxd8 19. Ng5 Ndf6 20. Nf3 Re8 21. a5 b5 22. Nd2. 17. Nxh7 Kxh7 18. g4 Nc5 19. gxh5 g5 20. Qf2.
Mar-02-23  TheaN: I saw the concept of <17.Rxf7+> with 17....Rxf7 18.Ne6+ +-, so <17....Kg8>. Sadly, I missed the 'windmill' concept with 18.Rg7+! (Nxg7 19.Qh7# or the text) and played the slightly suboptimal <18.Rxh7 +->. Strangely though, even though White surrendered a tempo in an attack, it's not even much worse: +9 vs +10, because Black has no proper defense against the attack anyway.

White threatens Rxh5, Ne6 and Bc4+ in case the queen moves (and of course still Rg7+, but lets assume White continues to miss it). It's enough for the win, it's just two free pawns anyway, but kinda bummed I missed Rg7+.

Mar-02-23  Lambda: 17.Rxf7+, and since 17...Rxf7 allows the fork, the king has to move, so that was obviously a good idea. We can decide on the next move after black replies.
Mar-02-23  Brenin: A K-side fianchetto in the Najdorf, when Black has played e5, seems unnatural: the B is needed on e7, supporting the backward d-pawn, not on g7, staring at a well-supported and immobile e-pawn. Instead of castling into trouble with 14 ... 0-0, I would have castled away from it with 14 ... Bxh6 15 Qxh6 0-0-0, leaving White's Q remote from any central or Q-side action. Black could have reduced his losses with the zwischenzug (I love that word!) 16 ... Qc5+, so that after 17 Kh1 Kxg7 his Q is protected (but still forkable by Ne6+), but presumably he hadn't seen Rxf7+ at that stage. In any case, after 18 Rxf7+ Rxf7 19 Ne6+ Kh8 20 Nxc5 Nxc5 White has Q+P for R+N, and a much better position.

  Teyss: I found it only because I remembered Steinitz vs Von Bardeleben, 1895. Nice combo. At the end after 20...Kh8 21.Rxg6 Nf6, if you hesitated between 22.Be2 and g4 as I did, both win.

The game the regretted <Phony Benoni> is referring to is O Popovych vs J N Jacobs, 1967, a rare example of identical games, bar a transposition, leading to a clear win.

<TheaN> I was about to correct you (at last) on the windmill concept, thinking it must involve discovered checks. But no, after checking you are right (again), it can also be direct checks as here. Should have guessed that being Dutch you know something about windmills.

Mar-02-23  outplayer: i saw g4 immediately. then i looked at nh7 and discovered rf7 remembering some puzzles i have solved at
Mar-02-23  King.Arthur.Brazil: I really was looking at the board and seeing no mate, then my love for conquering enemy's ♕ becomes happy: 17. Rxf7+ Rxf7 18. Ne6+ (wins my beloved new girl! lgs). So, Black will refuse with 17...Kg8 So my tireless ♖ sacrifice again: 18. Rg7+ and again Kxg7 19. Ne6+ wins the q. But, Black didn't let me, Nxg7 So my (Q) kill him! 19. Qxh7#. Good story for today.
