Jan-27-07 MaxxLange : Yates opens up the can!

He is an interesting player, kind of in this class of forgotten masters, the also-ran players from the 20s and 30s who were very strong chess masters, but weaker than Capablanka and Alekhine and Lasker et al.

Jan-27-07 ianD : got it as far as Nxh7+.

hard to see anymore from the initial position



Jan-27-07 Shajmaty : <al wazir: My move was 19. Nxh7, [...]> So was mine. Saturday... too much for me, as usual.

Jan-27-07 Sibahi : YES .. I saw the key move, but was too lazy to follow t out.

Jan-27-07 ravadi : What is winning way for white after 19....Nf6?? I don't see any immediate win for white. I think it is far better than text.

Jan-27-07 Themofro : Got it! Great combination.

Jan-27-07 blair45 : Computers? we don't need no stinking computers! I got it without a computer (more or less). Ref:dzechiel's comment -- it would be fun to work up a collection of games with brilliant refutations to brilliant sacs. I think it could be done. To Chess Games credit, they present these games as problems from time to time.

Peligroso Patzer : After White's Rook sac on move 19, Black's poor King had "No Haida Place".

Jan-27-07 Minty : <ravadi: What is winning way for white after 19....Nf6?? I don't see any immediate win for white. I think it is far better than text.> I think white just gets a nice safe advantage after 20. Rxe7 Qxe7 21. Nxh7 Kg7 22. Nxf6 Qxf6 23. Qg3 If I were black, I'd sooner take my chances with 19... dxe4, than suffer after that.

kevin86 : I saw this one coming! Great sacs for white-black is left virtually en prise everywhere.

Jan-27-07 Fisheremon : <Minty: <ravadi: What is winning way for white after 19....Nf6?? I don't see any immediate win for white. I think it is far better than text.> I think white just gets a nice safe advantage after 20. Rxe7 Qxe7 21. Nxh7 Kg7 22. Nxf6 Qxf6 23. Qg3 If I were black, I'd sooner take my chances with 19... dxe4, than suffer after that.> Right, but a much better defense was 19...Nd6.

Jan-27-07 aazqua : THis is one of the easiest Saturday puzzles I've seen, but then again most of these puzzles seem pretty easy. The rook sac SCREAMS to be played. I assumed black wouldn't recapture with the pawn as it appeared completely hopeless. White's bishop instantly becomes the best piece on the board and lanes are opened all over for white's attack.

Jan-27-07 uuft : Not too difficult to spot the rook-sac. I found 21. Qh6+ more difficult to find... Okay, so I didn't! Still, looks(!) like one of the easier saturday-puzzles.

Jan-27-07 THE pawn : I got the puzzle, but in an actual game, I'm not sure I would have seen that.

Jan-27-07 Grampmaster : If I were playing, I believe I would have played 25.Rxd6+ instead of White's Nf6+ as I think it was easier for me to follow the continuation 25...Kxd6 26.Qxd8+ Rd7 27.Qf6+ It just seems to me White's pieces are now more active. Can someone please explain to an old codger like me what the likely result is to be with this variation? Thanks.

Jan-27-07 ALEXIN : Missed. I thought 19. Nxe4 but there are defenses for black.

Jan-27-07 MORPHY MARVELLOUS : I saw Rxe4 and the continuation, but havent solved the continuation if blak plays Bf5 or Nf6 rejecting the white sacrifice.

Feb-29-20 stacase : Hmmmm, 19.Rxe4 or 19.Bxe4 I went with the Rook and cleaned house. (-:

Feb-29-20 Walter Glattke : Good morning, 20.-Kg7 21.Qxh7+ Kf6 22.Nxe4+ Rxe4 23.Qf7+ Kg5 24-f4+ Kh6 not good, 22.Nf7 Rxf7 23.Qxf7+ Ke5 24.c3 seems better

chrisowen : Yesterday like get it off my chest and then?

Feb-29-20 RandomVisitor : 18...Nf6 and 18...Qd6 each look better for black

A.2) 20... Kf8 21.Qh6+

A.2.a) 21... Ng7 22.Nxh7+ Ke8 23.Nf6+ Kf8 24.Qh8#. A.2.b) 21... Rg6 22.Nxh7+ Ke7 23.Qg5+ Kd7 24.Nf8+ Kc7 25.Qa5+ wins. A.3) 20... Kh8 21.Nf7+ Rxf7 22.Qxd8 wins decisive material. A.4) 20... Kg7 21.Qxh7+ Kf6 (21... Kf8 22.Qg(h)8#) 22.Qh4 (threatens Ne6(f7)+) A.4.a) 22... Kg7 23.Nf7 with the double threat Qh8# and Nxd8 (23... Rxf7 24.Qxd8). A.4.b) 22... Qd4 23.Nxe4+ Kf5 (23... Ke5(g7) 24.Qxe7+; 23... g6 24.Qxg5#) 24.Re1+ wins the queen. A.4.c) 22... Qb6 23.Nxe4+ followed by Qxe7+ wins decisive material. A.4.d) 22... Ke5 23.Nf7+ wins decisive material. B) 19...
