Nov-05-09  markwell: no, there's no mate with merely g4; the mate is shortly after the black queen falls

30...Kf5 31. Qd7+ Kg6

(31...Ke4 32. Nd2#)

32. Qg4+ Kf7

(32...Kh6 33. Qg5#)

Mar-02-13  Abdel Irada: And yet another <FSR> special.
Mar-02-13  goodevans: <Boomie> 33.Qd7+ just won't do. Black just repeats with 33...Kg6.

Instead, 33.Rc7+ mates quickly.

  kevin86: black is even in material,but is in dire straits-that's the walk of life.
Mar-02-13  bengalcat47: Dr. Lasker would've enjoyed this game, seeing such brilliant play arising from his favorite Ruy lopez Exchange variation.
Mar-02-13  Boomie: <goodevans: <Boomie> 33.Qd7+ just won't do. Black just repeats with 33...Kg6. Instead, 33.Rc7+ mates quickly.>

Oops. 33. Nxe5+ seems the most effective.

Mar-02-13  Davalillo: Thank you. When I first became interested in chess, the big American names were Walter Browne, Grefe, James Tarjan, Kim Commons and Lubosh Kavalek..

  offramp: A very clever and imaginative solution!
Feb-20-15  Cheapo by the Dozen: I just stopped with what's below. I'm not wholly convinced that the game line is better.

------------

I'm confused. 24 Qxc7 threatens:

Mate at d8.
Qxc8+ or, if the bishop moves, Qb8+.
Qc6+ forcing a queen exchange (with White the exchange up).

Black's kingside threats don't look like much, and the fork at e2 won't restore material equality for him.

I don't see why there's a difficult puzzle here.

Feb-20-15  Cheapo by the Dozen: <Davalillo>,

You might enjoy the link in my profile. It has an explicit mention of Commons and an implicit one of Tarjan (unnamed because I wasn't present for the story).

Feb-20-15  Oliveira: <Cheapo> Well, I think after 24.♕xc7 Black simply castles.

For my part, after the game's 24.♖d8+ ♔xd8 25.♕xc7+ ♔e8 26.♕xc8+, I failed to consider 26... ♔e7, but only 26... ♔f7, which loses readily to 27.♖c7+. The difficulty of the puzzle lies solely in finding the precise mate combination.

Feb-20-15  M.Hassan: "Difficult"
White to play 24.?

33.Qd7#

Feb-20-15  ozu: Well, I got the first three moves right and had the rook on c7 for the 4th move.... Does rook on c7 for the fourth white move do the trick? Sorry, if somebody already covered this move. I didn't see that anybody had. As for the first moves; usually these puzzles start with forcing moves and the impending fork of rook and king only accentuates this likelihood. And the initial rook sacrifice puts blacks king in a pretty ugly position. Then it's a matter of working out the black kings two responses. And I figured he had to take the rook. Now here comes the white queen. Hard to keep track of this stuff in one's head.
Feb-20-15  ozu: ..oh man. I guess blacks king moves to d6 and I'm open to a lot of tactics.
Feb-20-15  Oliveira: <Cheapo> Nice article. Definitely worth the read.
Feb-20-15  ozu: I was so close..
