 | | beenthere240: Boy is white to play on move 21 a great candidtate for a Wednesday puzzle. How annoying that must have been for black. |
 |

 | | Marmot PFL: 21.Bh7+ Kh8 22.Bg6 uses tactics to exploit the weakness of f7 and win material. |
|
| Oct-31-07 | | thegoldenband: How prescient of <beenthere240>, eh? |
|
| Oct-31-07 | | Manic: Took me around 5-7 minutes to see it. I saw the idea of a potential threat of a knight fork on g6 and had looked at Bg6 immediately. I was almost ready to give up. |
|
| Oct-31-07 | | newzild: Yeah, took me a little while, too. I was looking for sacs, but nothing worked. Then I noticed that after Bh7+ the K and Q were nicely set up for a knight fork. After that, it's almost impossible to miss Bg6. |
|
| Oct-31-07 | | mkrk17: Doesn't Nc6 also straight away win the exchange for white.. ? |
|
| Oct-31-07 | | zb2cr: I saw this one in around 1 minute. The
check eases the King into position to be threatened by a fork, then 22. Bg6 provides a support for the fork on f7. The Bishop is immune from capture, since a secondary fork (of King and Queen) would then materialize. The combination wins the exchange for White.Black resigned on move 28, BTW, because he was going to lose another Pawn and White would extricate his Bishop. After 28. ... Qxd6; 29. Bxf5, Qe5; 30. Bxe6+, Qxe6; 31. Qd2, Qf5; 32. Kf1, b6 White is up by the exchange and a Pawn, and his Rook is poised to dominate the open c-file or e-file. |

 | | Infohunter: <mkrk17: Doesn't Nc6 also straight away win the exchange for white.. ?> Well, no, as after 21...bxc6 the Rook at a6 is still defended, now by the Bishop at c8. |
|

 | | dzechiel: White to move. Material even. "Medium/Easy".
Looking for forcing moves I see:
- 21 Bh7+ (the most forcing)
- 21 Rc7
- 21 Ng6
Mostly I'm drawn to
21 Bh7+ Kh8 22 Bg6
Black can't take the bishop, and we are now threatening 23 Nxf7+ and 24 Nxd8. The only way for black to save the rook is to move it (22...Kg8 allows 23 Bxf7+ Kh8 24 Ng6+ and 25 Nxe7). After 22...Re8
Not 22...Rd5 as that allows 23 Rxc8
23 Bxf7
On the rook as well as threatening 24 Ng6+. This seems to win an exchange and pawn for sure. |
|
| Oct-31-07 | | Fezzik: My first thought was that this was a little difficult for a Tuesday puzzle. It's perfect for a Wednesday puzzle though! |
|
| Oct-31-07 | | moppa: I actually looked for Bh7/Bg6 but rejected it for some reason. Can't remember. Too tired. |
|
| Oct-31-07 | | willyfly: Material is theoretically even.
White can give check at will with  h7+ and drive the  to h8. But then what?! White could sac the  with 21 g6 fxg6 22 xg6 h8 but that doesn't accomplish much either. I am intrigued by 21 d5 but it seems Black has plenty of good responces such as  d6 or  ad6 Actually after 21 d5 d6 22 h7+ h8 23 xf7# so if we can get the off the 7th rank we might have a plan. I've spent enough time on this. I give up. I'm going to look now. -----
22...f5 - I'm not sure if I get it. |

 | | MostlyAverageJoe: <dzechiel: ... 21 Bh7+ Kh8 22 Bg6 .... Black can't take the bishop, and we are now threatening 23 Nxf7+ and 24 Nxd8. The only way for black to save the rook is to move it (22...Kg8 allows 23 Bxf7+ Kh8 24 Ng6+ and 25 Nxe7> Better yet:
22. ... Kg8 23. Bxf7+ Kh8 24. Ng6+ Kh7 <forced> 25. Nxf8+! Kh8 <forced> 26. Qh7# Therefore after 22. ... Kg8 23. Bxf7+ black would have to play 23 ... Qxf7, trading his Q+P for white's B+N. |
|
| Oct-31-07 | | Pwned: <dzechiel: .... After
22...Re8
Not 22...Rd5 as that allows 23 Rxc8
23 Bxf7
On the rook as well as threatening 24 Ng6+. This seems to win an exchange and pawn for sure.> Or even better for white after 22...Re8 is 23. Nf7+ Kg8 24. Bh7+ Kf7 25. Qg6# |
|
| Oct-31-07 | | cyruslaihy: wat??? winning the exchange is the answer? no mate? |
|
Oct-31-07
 | | a q maclanahan: yes, the puzzle is to find the best move, mate is not required. if you click on the link on the home page beneath the puzzle diagram the ground rules for the puzzles are discussed. |
|
| Oct-31-07 | | Jesspatrick: I play the black side of the Cambridge Springs defense, and I don't like 10...c5. Though the idea is to give white an isolated d-pawn, it appears to be a waste of time. It's better to play 10...Re8 and prepare 11...e5 |
|
| Oct-31-07 | | anandrulez: <cyruslaihy: > it will lead to a mate soon ...some 20-30 more moves maybe |
|
| Oct-31-07 | | greensfield: How to get a Knight in a position to create havoc
<21.Bh7+ Kh8(forced)22.Bg6!
if <22...fxg6 23.Nxg6+ Kg8 24.Nxe7+ Bxe7>(winning Queen for Knight) if <22...f5 23.Nf7+ Kg8 24.Nxd8 Qxd8> (winning the exchange with d5 to come) if <22...f6 23.Nf7+ Qxf7(23...Kg8 24.Bh7+ Kxf7 25.Qg6#)Bxf7>(winning Queen or mate) if <22...Qf6 23.Nxf7+ Kg8 24.Nxd8 Qxd8 25.Qf3> (winning exchange with d5 to come & threat Qf7+) |
|
Oct-31-07
 | | gawain: I saw White's moves Bh7+ and Bg6 but I did not see the obvious reply ...f5. So I imagined that the combination was even more decisive than it really is. Winning a clear exchange is decisive enough, though.
I enjoy puzzles where the Bishop, having checked at h7, is able to hang around in the vicinity (g6 or g8) and cause trouble. |
|
| Oct-31-07 | | psmith: well, that was pretty easy. whereas yesterday's i didn't get at all... |
|
Oct-31-07
 | | RandomVisitor: 10...Bd7, 10...Qc7, or 10...Re8 were all better than 10...c5, equalizing and perhaps avoiding later problems. |
|
| Oct-31-07 | | HOTDOG: Petrosian played a similar move against Taimanov
Petrosian vs Taimanov, 1955 |
|
Oct-31-07
| | gawain: Thanks <HOTDOG>. That game is a good example. |
|
Oct-31-07
 | | kevin86: I missed this one-relying on a possible sac at g6 by the knight to bring in the queen. I couldn't find anything afterward. |
