| Oct-26-07 | | wouldpusher: The catch here is 28. ♗c5!!, which gains a vital tempo, removes the guard, and opens the third rank for ♖h3. I considered 31. ... ♗d7 as best in order to stave off immediate mate, but 31. ... ♗d7 32. ♕xf8+ ♗xf8 33. ♖xb8 is clearly winning anyhow. Black paid dearly for not giving time to develop the QB earlier. |
|
| Oct-26-07 | | whiteshark: I only thought of <25.Rxd7 Bxd7 26.Bc5 Qd8 27.Nxh5> with various strong threats (28.Nf4 or 28.Bf7). Now <27...gh5 28.Qh4 Bg4 29.Rxd8 Rbxd8 30.h3> and white should win. |

 | | Jimfromprovidence: Doesn’t 32… Nxf8 avoid mate, allowing the black king an escape square at h7? |
|
| Oct-26-07 | | kevin86: A very forceful ending with white attacking along the h-file and later,the eighth rank. Black king WAS really cornered! |
|
| Oct-26-07 | | Men Tal: I too had considered Bc5, attempting to deflect the Queen. But Black has 'zwischenzug', an in-between move, Bg4, uniting it's back rank Rs and forking the Q and R, forcing White to capture it and allow Black to then capture at c5. White has lots of K-side pressure and can recapture the piece (the N at h7) with a series of moves 30. Qf5, 31. Rh3 and 32. Rd7, with an easy win. |

 | | gawain: I saw that Nf5 was the right move. I'd like to think I would have played it over the board and hoped for the best even if I had not yet worked out the Q deflection or the rest of the details. |
|
| Oct-26-07 | | patzer2: For today's puzzle solution, White infiltrates and demolishes the weak Black King-side castled position with 25. Nf5!! The alternative 25. Nxh5, pointed
out by <Random Visitor>, also wins using this theme. My solution was 25. Ba7, which also seems to win but is not as strong as the move played. The simple idea 25. Rd6, attacking the isolated pawn on c6 also seems to win easily. P.S. Anyone care to run a computer analysis and post the results on 25. Ba7 and 25. Rd6? |
|
| Oct-26-07 | | willyfly: Material is dead even. I don't have much time at all for this today but I'm guessing an attack might start with a ♘ sac 25 ♘xh5 to clear the g-file and give Black an isolated h-♙. Then play the ♕ to h4. That's all. Time to look. |
|
| Oct-26-07 | | pawnofdoom: Based on the games from the previous few days, I was surprised the answer to this puzzle wasn't 0-1 |
|
| Oct-26-07 | | TrueBlue: < xrt999: <TrueBlue: not to bad. Back to my normal form. 25. Nxh5 gxh5 26. Qh4
Nf8 27. Qxh5+ Nh7 28. Bc5
Black is toasted >
I played this line also, but since the c8-h4 diagonal is now open, Black responds with 28...Bg4! attacking the queen. White's attack is stopped. ouch. both queens are attacked, and White must take the bishop. Black also takes your beloved bishop on c5, and the game continues with white attacking h7. Although White has the advantage the outcome is less clear. The game goes on for about 20 moves and with all the calculations involved its anyone's game. cheers.>
allow me to disagree. I saw the bishop exchange, and I fail to see how this diminishes white attack |
|
| Oct-26-07 | | solstys: I also got the same line as <moppa> and I think it works, though more slowly. My weak computer program prefers 28...Bg4 in the line, but ultimately, white gets a +3.5 score. Any thoughts? |
|
| Oct-26-07 | | gBizzle: i got Nf5 but didnt get Qh4 |
|
| Oct-26-07 | | PositionalTactician: To True Blue:
Well, I guess both moves win, but one wins more spectacularly, quickly, easily etc. I think you agree that it would be much better to deny black the change to play ...Bg4 or have a bishop controlling h3 |
|
| Oct-26-07 | | swissteam: Why not 25. Nxh5 instead? |
|
| Oct-26-07 | | jperr75108: Nice problem. |
|
| Oct-27-07 | | MostlyAverageJoe: <patzer2: P.S. Anyone care to run a computer analysis and post the results on 25. Ba7 and 25. Rd6?> Here it is, 18-19 plies deep after the move, hence most likely not trustworthy after the first 7 plies. I did not do any confirming analysis; the lines are straight out of Hiarcs. After 25.Ba7 (18 plies):
1. (+3.49) 25... Rb4 26. Rxd7 Bxd7 27. Bc5 Qd8 28. Bf7 Rd4 ... 2. (+3.98) 25... Bh6 26. Bxb8 Nxb8 27. h3 h4 28. Ne2 f5 ... After 25. Rd6 (19 plies):
1. (+2.28) 25... Nf8 26. Rxc6 Be6 27. Bc5 Qf7 28. Bb6 Rbc8 ... 2. (+3.76) 25... Ra8 26. Rxc6 Nb8 27. Bc5 Nxc6 28. Bxe7 Nxe7 ... |
|
| Oct-28-07 | | solstys: Can someone post analysis of 25. Rxd7 instead of 25. Nf5? Thanks in advance. |

 | | Check It Out: I had the thought maybe chrisowen is using one of those verbal to written translators. Back in the day he used to write coherent posts. |
|
| Oct-17-24 | | Allderdice83: I saw 28. Bc5 right away, but then completely missed 29. Rh3! I had 29. Qxe8+, when 29 ... Qf8 30. Rd8 Qxe8 31. Rxe8+ Bf8 32. Rdd8 wins the light-squared bishop and should be winning for White, although Black's central pawns are a threat. |

 | | scormus: <Allderdice83 ... missed 29. Rh3!>
So did I. I thought Ra3 would might come into it, but 29 Qxe8+ looked completely winning and it's what I went for. When I played it through I thought I must have missed a better move. Never mind, SF17 rates them almost the same, 29 Ra3 etc. just getting the nod by a few tenths. Though I admit it looks the more classy line. |
|
| Oct-17-24 | | Halldor: My first thought was to move the rook to h3 and therefore play Bc5 first to clear the way, especially since the black queen is the only defender of the rook on e8, so I thought: 28 Bc5! QxB 29 QxR Qf8. Now I first thought of moving the queen back to h5, but then decided to play Rd8 (despite my original plan, Rh3), 30 Rd8 QxQ 31 RxQ† Bf8 32 Rdd8, gaining more material. — Not the strongest line, but still a winning position. |
