Dec-05-12  James D Flynn: Material is equal but Whites pieces are menacing the Black K-side, in particular the h7 square. 14,Bxh7+ Kxh7 (if Kh8 15.Bg5 Qc8 16.Qh4 Re8 17.Bg6+ Kg8 18.Qh7+ Kf8 19.Qh8#) 15.Ng5+ Kg8(if Kg6 16.Qh4(threat Qh7#) Rh8 17.Qxg4(now the threat is 18.Ne6+ Kh7 19.Qxg7#and defending g7 by Rg8 is not an option because 18,Ne6+ Kh7 19.Qh5# and defending by Qf8 loses the for a N) f5 18.exf6 Qc8 19.Ne6+ Kf7 20.fxg7+ Ke7 21.Bg5+ Kd7 22.Nf8+ Kc7 23.Qxc8+ Rxc8 24,gxh8=Q with decisive material advantage) 16.Qh4 Re8 17.Qh7+ Kf8 18.Rxf7#

  playground player: There's something about Bxh7+ that almost compels the move.

  kevin86: This is classic BxP+ KxB N-N5+ type of chess. The knight allows the white queen into the attack by blocking black's.

I think the puzzle is really about the first three moves.

  morfishine: Got this far: <14.Bxh7+ Kxh7 15.Ng5+ Kg6 16.Qh4 Bh5>

But then varied with <17.g4 Rh8 18.gxh5 Rxh5 19.Qg3 Rxg5 20.Bxg5 Qxg5 21.Qd3+ Kh6 22.Rxf7 Qg6>

  chrisowen: Heading him off at the pass inceed the point re d3 as h7 in oratory I thin 14.Bxh7+ knight will alpine along g5 in then engage, queen in h4 et now in bind duty it a poetic 16.qh4 finish he bending h5 in herd h3 or dervish in g4 lesson even ar good ridge g3 - all one eyes the bishop in ghosting along it black face in whistle dixie a serious blow to his kingside after I fickled 17.Qh3 landest in e1 to h4 open in shut heading bishoph5 or deem in traced queen a sac in g5 light upper hand ware house in wall Martz crowded out in caining hurt river h3 and a lexicon g3 also g4 bottomed in.
Dec-05-12  Patriot: This looks like a classic bishop sacrifice--14.Bxh7+.

14...Kxh7 (otherwise drop a pawn for nothing) 15.Ng5+

15...Kg6 looks like the real test (not 15...Kg8). 16.Qg3 looks winning. 16...f6 poses no challenge since 17.Ne6 . And any bishop move allows 17.Ne6+. I don't see a defense.

15...Kg8 16.Qh4 threatening mate in 1. This looks defenseless.

Dec-05-12  Patriot: I see now that 15...Kg6 16.Qg3 Nxe5 evens things out a lot. 16.Qh4 is much better.

  FSR: 14.Bxh7+ is obvious enough, although I missed the defense Black tried in the game.
Dec-05-12  TheBish: Rohde vs W Martz, 1977

White to play (14.?) "Medium/Easy"

14. Bxh7+! Kxh7 15. Ng5+ and now:

(A) 15...Kg8 (not 15...Kh8 16. Qh4+ and mates, or 15...Kh6 16. Qh4+ Kg6 17. Qh7#) 16. Qh4 and Black will have to give up his queen for White's knight to stop mate, as 16...Re8 17. Qh7+ Kf8 18. Rxf7# doesn't help.

(B) 15...Kg6 16. Qh4 Bh5 (or 16...Rh8 17. Qxg4) 17. g4 and White has a winning attack.

Dec-05-12  Abdel Irada: <Once>: Thank you for the Fritz report.
Dec-06-12  sushijunkie: I'd wager more sacs/combos have happened starting there than any other square.
Dec-06-12  Abdel Irada: <sushijunkie>: I'm not sure where one would be able to confirm such a statistic, but my impression is that more sacrifices fall on f7/f2 than elsewhere.

  FSR: <Abdel Irada> That's my impression too. One could test this hypothesis with Sacrifice Explorer.

I believe he means d3.

  offramp: Yes, good pun...more meaningful because it's a Greek Gift.
Oct-08-13  sorokahdeen: This game is intense!

First, it's one of the better examples of move-counting ala Znosko-Borovsky (The Middle-Game in Chess) since Morphy v. Consultants. Black's knight maneuvers install so many moves into it that when it's exchanged, black suddenly has next to nothing in the way of development, in a position where you can count white's moves and see that he is two or three moves up by the time black plays 10 ...c5, which throws another tempo into the dark-squared bishop.

The recognition that a variation on the classic h7 bishop sacrifice was present definitely separates the men from the boys, as did Rhode's Qh3! That maintained his roaring initiative with a basketload of ugly threats that forced black to shed his queen to try and absorb some of the attack.

That was a wonderfully dynamic game. ! Wish I'd played it.

  offramp: I think that Martz did very well to keep the game going after a bad opening. He was really on the ropes but kept finding little jabs. Did Rohde miss a better opportunity earlier on?

  kevin86: White is up a queen for two pieces-should be an easy win.
Nov-03-13  Jjoq: <morfishine> 17. g4 Rh8 18. Qh3 (instead 18. gxh5+)
