| Nov-24-15 | | Mehem: <roentgenium> The position after 33.Rxd5 is won for White, but Black shoudn't facilitate the task by playing 33... Re5 and 37... Rxc5. The plan is simple: take pawns a7 & c5, reduce to 1 rook and we get something like this below:

the last barrier on f6 will soon fall as well. |
|
| Nov-24-15 | | saturn2: <roentgenium: Furthermore, does Black get good drawing chances if he doubles his Rooks on the 2nd rank and proceeds with ...Rh2+ ?> If black doubles rooks it does not seem dangerous. White can grab the c5 pawn in between. If black plays Rh2+ then Kg4 and after Ra4+ Kf3 black has no check.
I considered the puzzle solved after 31 h5+ because the black pawns are not connected and far advanced. |

| Nov-24-15 | | Ratt Boy: <khense: After 31 h5+, KXh5; 32. Rg7, Ne3; what does Black do after 33 Re1... >
Am I missing something? I'm thinking 31.h5+, ♔xh5 32.♖g7, ♘e3 33.♖f5+, ♘xf5 34.g4#.

I like this better than 31.h5+, ♔xh5 32.♖g7, ♘e3 33.g4+, ♘xg4 34.♖f5#.

|
| Nov-24-15 | | thegoodanarchist: <Cheapo by the Dozen: I easily got to the game line. I don't understand why Black immediately exchanged a pair of rooks.> I think in order to convert the f pawn into a passer. Practical chances and all that. Bishops are poor defenders against multiple passed pawns. |
|
| Nov-24-15 | | Marmot PFL: Rooks and bishops tend to work much better in open positions than rooks and knights. 29...Nxf4+ might be a draw but the black king is under attack and can't retreat because of Rb7. 30 Bc1 and if 30...f5 31 Re1 threatening Re6+ and if Nf6 the pinned knight is lost anyway. So black loses a piece and the game. |
|
| Nov-24-15 | | CHESSTTCAMPS: Black has the material advantage of knight plus pawn for a bishop, but with the king having only one adjacent safe square, clearly white is in control. At first, I thought 31.g4 did the trick, but after Re7, black has an escape row for his king. I decided to settle for 31.h5+ Kxh5 32.Rf5+ (Rg7 Ne3 stops both mate threats) Kg6 33.Rxd5 with a won ending. |

| Nov-24-15 | | kevin86: The pawn decoy move set up the win of the knight. |
|
| Nov-24-15 | | TheFocus: Nice puzzle. h5+ was a good move that wins a piece. <Beside Bxe3, what is the only winning move for white?> Kh6 |

| Nov-24-15 | | BOSTER: < FSR: I was expecting a mating>. Because <patzer2> could foresee all mating possibilities in this pos 10 years before, and did not find anything, you'd be satisfied with
31.h5+ Kxh5 32.Rf5+ Kg6 33.Rxd5.
Maybe black was in hurry to "move" f6 pawn
on "e" file.
After this the Q was only one.
Was such " pants" like a5-d5 (Russian term to describe two separated pawns) <fit > for Bishop or not.

Beside Bxe3, what is the only winning move for white?> Excellent side puzzle, Jim!
Maybe White can win with 1.g6 e2 2.Bd2! a3 3.g7 a2 4.g8=Q a1=Q 5.Qg6+ Ke5 (only move) 6.Qg7+, winning the Black queen |

|
| Nov-24-15 | | LIzzard: Settling for the eventual win with material seemed to simple - I stared at this for a good 7 min or so trying to find a mate, but with only 3 checking moves, none came out. Nice to see some variety in the puzzles I guess! |
|
| Nov-24-15 | | Olsonist: Good Tuesday puzzle and a nice change of pace from bam, bam, thank you mam.
I declared victory after Rf5 but the endgame technique was pleasant. |
|
| Nov-24-15 | | Halldor: The Black King is in critical position, nearly stalemate, so I looked for a mate, and after few minutes I found 31 h5+ Kxh5 and 32 Rg7, which seems to be almost mate. Now White can mate with either g4 or Rf5, so Black has to play 32… Ne3. But now the knight seems to be overworked, it has to guard both the f5 and f3 squares to prevent mate. I thought I had this, say 33 g4+ Nxg4 34 Rf5# but unfortunately the knight blocks the way for the Bishop so Black can instead play the teasing move 33… Kh6. 33. Rxf6 seems good, but my vision is getting blurred that far into the position. |
|
| Nov-24-15 | | M.Hassan: Sides are equal but White has a Knight for a Bishop. 31.h5+ Kxh5(forced)
32.Rf5+ Kg6
33.Rxd5
White wins a piece for a pawn |
|
| Nov-24-15 | | Schach and Awe: Isn't the final position, after White plays Ba3, drawn? Black can push the e pawn, drawing the White King away from the protection of the g pawn, and the Black King will eventually snap up White's last pawn. |
|
| Nov-24-15 | | Pinkerton: The continuation to 43...e4 is 44.Bc1 |
|
| Nov-24-15 | | devere: <Schach and Awe: Isn't the final position, after White plays Ba3, drawn?
Black can push the e pawn, drawing the White King away from the protection of the g pawn, and the Black King will eventually snap up White's last pawn.> After 43...e4 44.Bc1 or Bc5, Black is in zugzwang and White seems to win easily. |
|
| Nov-24-15 | | AnotherNN: I agree with others who said that after 31.h5+ Kxh5, the stronger move is 32.Rg7 since Black cannot stop immediate mate from White with either 33.Rf5++ or 33.g4++. If Black tries 32.Nd3, then White plays 33.Rf5+ followed by 34.g4++. |
|
Nov-25-15
 | | The Long Diagonal: <AnotherNN> <If Black tries 32.Nd3, then White plays 33.Rf5+ followed by 34.g4++.> Nope. As many kibitzers have pointed out, after 33.Rf5+ black has 33. .. Kh6 and white has no mate. |
