| Jan-27-11 | | kevin86: This brilliant finish employs a block and a decoy;the bishop would love to take the rook but his own queen is in the way-the queen can take,but then she has to abandon the protection of the pawn at g2,which is needed to prevent checkmate. Mate is forced. |

 | | Jimfromprovidence: Just a FWIW note: if white tries a swindle after 29... Re1+ 30 Kh2 Rh1+ 31 Kg3 Rxg5+ 32 Kf4 (keeping the mate threat gxh7# alive)... 
click for larger view ... then black wins nicely with 32...Qc1+, with mate next move.

| Jan-27-11 | | MaczynskiPratten: <Jimfromprovidence>'s last diagram is a nice example of economy of force. 3 Black pieces (Q, R, B) mate a White King in the centre of the board with 8 flight squares by criss-crossing all escape lines. Very elegant! |
|
| Jan-27-11 | | VincentL: "Medium".
White threatens mate with gxh7.
But it seems fairly straightforward to avoid the mate and win material. 29....Re1+ 30. Kh2 (only move) Be5+ 31. g3 Rxb1, and now black has won a bishop and the
mate threat has gone.
This is not Thursday level. What have I missed? Let´s check. |
|
| Jan-27-11 | | VincentL: Well, the game line wins more quickly and is neater - but does my line not also win? L must read the other posts. |
|
| Jan-27-11 | | Medieval Knight: Didn't get it.
After 29....Re1+ 30. Kh2, I was hung up on 30....Qxh3+, etc, which leads nowhere. Great puzzle |
|
| Jan-27-11 | | CHESSTTCAMPS: In this wild position, white has sacrificed a rook for a pawn and an all-out kingside attack utilizing all remaining major and minor pieces. White threatens 29.gxh7# and has a secondary threat of Rd8+. On the downside, white has left the back rank undefended. Nonetheless black has a number of chances to go wrong. To mention a few losing candidates: (I) 29...Rxg5?? 30.gh7# (II) 29... hxg6?? 30.Rxg6+ forces mate. (III) 29...Re1+?? 30.Kh2 Be5+ (Rxb1 31.Rd8+) 31.f4 Bxf4+ 32.Qxf4 fxg6 33.Qf6 wins. Complex is (IV) 29... fxg6? 30.Rxg6+?! (Rd8+ appears stronger) Kf7 31.Qf4+ Rf5 32.Bxf5 Re1+ 33.Kh2 Be5. But black need not offer white any serious counterchances: 29... Rc1+!
Prepares Be5+ much more effectively than 29... Re1+. The counterattack wins for black: A) 30.Qxc1 Qxc1+ 31.Bxc1 Re1+ 32.Kh2 hxg6! (not Be5+? 33.f4 Bxf4+ 34.Bxf4 Rxb1 35.Rd8+ Kg7 36.gxf7 Kxf7 37.Rd7+) and white can't meet the double threat of Rxc1 and Be5+: A.1) 33.Rd8+ Kh7 34.Rxh8+ Kxh8 35.Bb2+ Kg8 33.Bd3 Rd1 34.Be2 Rd2 wins. A.1.1) 34.Rd7 Be5+ 35.f4 Bxf4+ 36.g3 Rh1#
A.2) 33.Bd2 Rxb1 34.f4 Rb2 leaves white with no counterplay. B) 30.Kh2 Be5+ 31.f4 (g3 Rh1#) Bxf4+! 32.Qxf4 Rxg2#
B.1) 31.Qxe5 Rxe5 32.gxh7+ Kh8 wins.
Time to review kibitzing and game. |

To add insult to injury, Chessmaster improved white's play in my A.1 line with 34.Bxg6+! giving the following position: 
click for larger viewPlaying black w a Game/10 minute time limit, I continued 34... Kxg6 35.Rxh8 Rxc1 36.Rg8+ Kf6 37.Kg3 Rc2 38.Rb8 Be4 39.Rb6+ Rc6 40.Rxc6+ Bxc6 41.b4 and I went on to blunder into a loss trying to win it. With white getting a 2nd pawn for the piece, it may be very difficult to win this even with best play. |

| Jan-27-11 | | BOSTER: Can you imagine,that only one move before the position on diagram we have had the position where white was equal.

Here white to play , where they played "unexpected" 28.Rxd6? leaving the back rank without protection.
But playing simply 28.Rxe8+ Qxe8 29.fxg6 hxg6 30.Qg4 or Qd2 they would have no any problem, and black nice combo will be still only available ,if...
But looking ahead white did not want disappoint <CG> and kibitzers and this is why they played 28.Rxd6. |
|
| Jan-27-11 | | Patriot: Material: Black has a rook for two pawns.
Threats: White threatens 30.Rd8+ and 30.gxh7#.
Black must start with check or defend directly against 30.gxh7#. I'll first sample 29...Re1+, since this looks very strong. 29...Re1+ 30.Kh2 Rh1+
A) 31.Kxh1 Qxh3+ 32.Kg1 Rc1+ 33.Qxc1 Qxg2#
B) 31.Kg3 Rxg5+ 32.Bxg5 Rxb1 33.Rd8+ Qxd8 34.gxf7+ Kxf7 35.Bxd8 Ok, I like 29...Re1+. Let's see what happened. |

| Jan-27-11 | | wals: Needed to be wide awake to get that one.
Rybka 4 x 64
White blunder: d 20 : 7 min :
(-#15):29.fxg6. Best,
1. = (0.00): 29.Rd8+ Re8[] 30.Rxc8 Rexc8 31.fxg6 hxg6 32.Qe7 R5c7 33.Qg5 Rd7 34.Kh2 Kh7 35.Qh5 Rd5 36.Qf3 Rd7 37.Qh5 Rd5 38.Qf3 Rd7 39.Qh5 Rd5 40.Qf3 Rd7 41.Qh5 Rd5 42.Qf3 Rd7 43.Qh5 Rd5 44.Qf3 31.Kh1, -#3, did't help. Could have prolonged the inevitable with
Kg3, -#14. |
|
| Jan-27-11 | | Patriot: In my line B, instead of 32...Rxb1 Fritz likes 32...Be5+ which is definitely better. Interestingly in line B, Fritz would rather play 34.gxh7+ over 34.gxf7+. I guess because it creates an outside passer (h3-pawn) for white which may be harder to deal with down the road, as a general principle in the endgame, although it doesn't make much difference here. But...it's all winning. I found this to be easy, seeing the patterns pretty quickly. I did hesitate for a short while after 31.Kg3 -- 31...Rxg5+ or 31...Rc3+? It didn't seem clear and in fact looked dangerous for black to play 31...Rc3+. Even if that wins, I trust 31...Rxg5+ much more. |
|
| Jan-27-11 | | MaxxLange: my post mortem:
I first asked what White can do on the move, and saw that he threatens mate in 1. But, I failed to notice an essential thing in the position - Black can play ...Rxg5. If I had noticed that, I would have seen that it does not stop the mate, and I would have started in analyzing Black's checks. SO: I analyzed the variation that was played and saw all of that...the Qg5 defends the usual end to that nice attraction to the pin mating combination, but it can be distracted by . 32..Rc1+! But I was worried about 31 Kg3, and the <STATIC IMAGE> I had, where the Queen on g5 isn't hanging, kept me from seeing that this is just crushed by 31...Rxg5+ Great puzzle today |
|
| Jan-27-11 | | WhiteRook48: I had 29...Re1+ 30 Kh2 Rh1+!! 31 Kg3 (if 31 Kxh1, Qxh3+ easy mate) 31... Rxg5+ 32 Bxg5 Be5+ 33 Bf4 Bxd6 34 gxh7+ Kg7 35 Bxd6 Qc3+ 36 Kg4 Qd4+ 37 Bf4 Bxg2 38 Kg3 Bxh3 39 Bh6+ Kh8 0-1 |
|
| Jan-27-11 | | SufferingBruin: Fell fore the ol' <Be5+> that others had already debunked. Never even considered f4. |
|
| Jan-27-11 | | Nullifidian: All of white's pieces are threatening a mate in 1, so something drastic has to happen for Black to save the game. The immediate ♖xg5?? loses to ♙gxh7#, so there seems to be only one option left on the board that answers: 29... ♖e1+
Play continues:
30. ♔h2 ♖h1+! 31. ♔g3 (♔xh1 ♕xh3+ 32. ♔g1▢ ♖c1+ and now either 33. ♕xc1 or ♖d1 leads to mate) ♖xg5+ 32. ♗xg5 ♗e5+ followed by 33... ♗xd6 leaves Black with a completely won position. |

 | | takchess: incredible. The king tried to get out but the rook kept pulling him back. |
|
| Jan-27-11 | | karnak64: My. How abrupt ... |
|
| Jan-27-11 | | MaxxLange: 28 Rxd6! was a beautiful move
Then White blunders.....so it goes... |
|
| Jan-28-11 | | TheBish: Sherzer vs Acs, 1998 Black to play (29...?) "Medium"
Not much time, but just got it. White was threatening mate with 30. gxh7# and also 30. Rd8+, so it's do or die time for Black. 29...Re1+ 30. Kh2 Rh1+! (decoy) 31. Kxh1
Or of course, 31. Kg3 Rxg5+.
31...Qxh3+ (the point) 32. Kg1 Rc1+! (the second point, and second decoy!) 33. Qxc1 Qxg2#. |
|
| May-05-14 | | SpiritedReposte: Access denied (pun would fit better if Acs lost tho lol) |
|
| Aug-07-17 | | clement41: Sherzer, who is a GM known for highly agressive play judging by his games, gets here a taste of his own medicine.
After 29 fg!? the position is strikingly similar to 
click for larger view in Geller vs Smyslov, 1965 , with exactly the same mating pattern being used although of course each has its own tactical specifics |
