 | | LIFE Master AJ: 24.RxP/KR7!
Black can thrash around a bit - but in the long run, there is no good defense - that I can see. |

| | LIFE Master AJ: Call this one: "Entry down an open file."
About 10-15 years ago, one of my students played a game, he was about 11 at the time. He went to a National Scholastic tournament. Later - he showed me a game where he had opened a file (due to an exchange) right towards his King. He was shocked when I found a mate very rapidly - fortunately for him, his opponent had missed it. Anyone who has studied the games of Morphy know that open files on a King, (esp. one caught in the center); is the quickest way to get annihilated. [ See Morphy vs Duke Karl / Count Isouard, 1858. ] |

| Jul-14-11 | | David2009: H P Garcia vs R Casafus, 1977 White 24? 24.Rxh7 looks dangerous: 24...Kxh7 25.Qh1+ Kg8 26.Qh6 f6 27.Rh1 fxe5 28.Bxe5 mates. No better is 26...f5 27.Rh1. Time
to check:
====
Black declines the sacrifice and loses differently. Here's the puzzle position:

| Jul-14-11 | | Patriot: 24.Rxh7 can almost be played with impunity. I say "almost" because 24...Kxh7 needs a little calculation and 24...f5 is the only critical candidate that I see. I spent 2 minutes on this even though 24.Rxh7 was my only candidate and I saw this candidate within a few seconds. |
|
| Jul-14-11 | | patzer2: <David 2009> I beat Crafty after 24.Rh7 Kf8 25.Qh1 Qd7 (your diagram above) with 26. Qh6+ Ke7 27. Qxg6 Rf8 28. Qf6+ Ke8 29. g6! . |
|
| Jul-14-11 | | psmith: <David2009> It is not difficult to win with the game line. Here is how it went for me against the EGT:
24. Rxh7 Kf8 25. Qh1 Qd7 26. Qh6+ Ke7 27. Qxg6 (at this point Black could really resign) Rf8 28. Qf6+ Ke8 29. g6 Qe7 30. gxf7+ Kd7 31. Rbh1 Qxf6 32. exf6 Ra8 33. Re1 Kc6 34. Rxe6+ Kb7 35. Bd6 Nd7 37. Re7 Kc6 38. Rxd7 ... need I go on? |
|
| Jul-14-11 | | psmith: Ah, I see <patzer2> and I think alike. |
|
| Jul-14-11 | | CHESSTTCAMPS: In this closed middlegame position, white's bishops have limited value for attack, but the semi-open h-file and the space advantage on the kingside give white a winning position. Experienced players will find the initial breakthrough without giving it much thought. 24.Rxh7! gives black no time to engineer an escape to the queenside: A) 24.... Kxh7 25.Qh1+ Kg8 (Kg7 Qh6+) 26.Qh6 f6 27.Rh1 Kf7 28.Qh7+ Kf8 29.gf Qxf6 30.ef and white mates in two more moves. A.1) 26...f5 27.Rh1 Kh7 28.Qh7+ Kf8 29.Qh8+ Ke7 30.Rh7# B) 24... Kf8 25.Bh5!! (OK, this bishop does have some attacking value!) gxh5 26.Rxf7+! Kxf7 27.Qxh5+ Ke7 28.Qh7+ Kf8 29.g6 Qd7 30.Qh8+ Ke7 31.Qf6#! B.1) 25... Ke7 (or Qd7) 26.Bxg6 wins.
B.2) 27... Kg8 28.Rh1 forces mate
I discovered B somewhat by accident, visualizing the Q on b1 and thinking that white had 27.Qh7+. After realizing the mistake, I was about to switch to the pedestrian 25.Qh1 when I noticed that 27.Qh5+ works just as well. Time to see how the game played out.... |
|
| Jul-14-11 | | CHESSTTCAMPS: <LMAJ> and other kibitzers have pointed out alternative ways that white can win after black declines the rook with 24... Kf8. Following is another winning move illustrated with <Jim's> award-winning 3-diagram presentation method. After 25.Bh5! the following position is reached:
click for larger view Crafty EGT actually defends this position with 25... Rb7 26.Bxg6 fxg6 27.Rxb7 which white wins easily with a modicum of attention. If black accepts the bishop, play continues 25... gxh5 26.Rxf7+! Kxf7 27.Qxh5+ 
click for larger viewThere are alternative paths from here, but one pretty finish is 27... Ke7 28.Qh7+ Kf8 29.g6 (Rh1 also wins) Qd7 30.Qh8+ (or Bh6+) Ke7 31.Qf6#

| | LIFE Master AJ: <Chessttcamps> I agree! :) |
|
| Jul-14-11 | | bengalcat47: Black's conduct of this game leaves much to be desired. He exchanged off his light-squared bishop for the knight at f1 without any good reason. Black's "well posted" knight at g3 doesn't really accomplish anything except forcing a rook to move. While most of Black's pieces are off gallivanting on the Queen side his poor King must face the enemy alone. |
|
Jul-14-11
| | LIFE Master AJ: I agree that Black's play (here - in this game) was very poor ... his opening of the h-file was most unwise. |
|
Jul-14-11
| | LIFE Master AJ: One person sent me an e-mail and asked me to annotate this game - I would say someone else will analyze the variations ... Black's play here is very lacklustre. |
|
| Jul-14-11 | | castledweller: this one seemed, to me, like a "monday" |
|
| Jul-14-11 | | DarthStapler: Got it |
|
| Jul-14-11 | | Fezzik: Rxh7 was easy to find, and easy to play in a blitz game. In a serious game, it takes tremendous confidence to sac the rook in this manner when Black has many moves at his disposal. Nice choice today, chessgames.com! |

 | | scormus: Why do I read these posts? I was quite satisfied with 24 Rxh7. If 24 ... Kxh7 B loses in short order, a quick clean death fitting for a warrior. If anything else then W should win sooner or later. Should've quit while ahead. I looked at the game and saw, hell 24 ... Kf8 and went straight for 25 Qh1 influenced by the straight win after 24 ... Kxh7. Easy, right? Had a real hard time and didnt find a forced win against all the possible 25 ... moves. All the time 25 Qf3 was staring at me. Thats 2 midweek puzzles I've messed up. Good thing I'm devoting the weekend to my family |
|
| Jul-14-11 | | psmith: <scormus>: Don't feel bad, 24...Kf8 25. Qh1 DOES win after all. Devoting a weekend to your family: excellent idea! |

| Jul-14-11 | | ColeTrane: I know inherently to capture on h7, but beyond that things get fuzzy . . . . can't . . . see . . . future.....need water . . . .& . . . .end game strategy . . . . ahhhhhhh........ |
|
| Jul-14-11 | | WhiteRook48: I had 24 Rxh7 Kxh7 25 Qh1+ Kg8 26 Qh6, and probably would have played 25 Qh1 anyway in response to 24...Kf8 |
|
| Jul-14-11 | | newton296: just smoked egt!
had 5 pawns to bare king in about 12 moves! just gotta barrel down the h file after moving a pawn to g7 and black has to give up a rook to prevent queening at h8! landed about 5 combos like this just today ! on playchess.com |
|
| Jul-15-11 | | kevin86: This breakthrough is obvious and not that difficult:sac the rook at h7,then enter with the queen. |
