 | | Richard Taylor: As far as I can see 18.d5 is unnecessary and 18. Rd3 wins |
|

| | Richard Taylor: The reason for d5 must be to block the diagonal that is Black's White-squared B so if 18. Rd3 Bxg2 19.Qxg2 Qd5 20. Qh3 Qg5+ 21. Kb1
I think White is still winning
but there is also 19. Rg3
hmmm 18. d5 stops it all in any case. |
|
| Dec-11-05 | | kevin86: A good finish! White was able to execute a good kingside attack vs black. I didn't even try this one-these Sunday puzzles are "murder"-as Hank Stram used to say-. |
|
| Dec-11-05 | | shortsight: <kevin86> I didn't try too. Saw until 15.Bxh7+ but brushed it off thinking that it will be perpetual instead of winning. In OTB play, I won't even try Bxh7 in the 1st place. Sigh ... |
|
| Dec-11-05 | | Neurotic Patzer: er.. on my last post I meant "and BLACK can only postpone mate". |
|
| Dec-12-05 | | snowie1: It's a neat game to just study in the final position. Black's only move ..Qxd3 still couldn't prevent mate it a couple of moves. and I agree that Black's 12..0-0 was not good with White's guns trained on the K-side. |
|
| Dec-13-05 | | LIFE Master AJ: To answer a friend's question, I hit upon the idea of ...Nxd7 and ...Bxh7+ rather quickly. What was not so easy to see, and took many minutes, was the idea 18.d5!, which is not such a simple move to spot in advance. |

| Dec-13-05 | | hayton3: <LIFE Master AJ> Name of friend?, title?, USCF membership no.?, what program was he using?, was he scratching his ___ at the time? |
|
| Dec-15-05 | | patzer2: White's 13. Nxd7!! prepares a winning demolition of pawn structure combination with the pseudo-sacrifices
14. Nf6+! and 15. Bxh7+! immediately following. |
|
| Dec-15-05 | | patzer2: <LIFE Master AJ> is correct in pointing out that 18.d5! is a key obstruction move in White's winning combination. The "obvious" alternative 18. Rd3!? Qd5! 19. Rh3 Qg5+! gives Black unnecessary counterplay and practical drawing chances. |
|
| Dec-15-05 | | hayton3: Yes, Fritz is correct in pointing out all these combinations. |
|
| Feb-14-22 | | whiteshark: For aesthetic reasons I would have preferred the silent final move <21.Rg1!>

| Dec-18-22 | | Dionysius1: Oh lor'. The days when chess and I were young....the teasing around h7. I applaud you for liking the solution theme. That's nice chess! |
|
| Dec-18-22 | | Brenin: A rather obvious initial attack, though the follow-up needs to be handled with care. 14 Nf6+ gxf6 (otherwise the Q is lost) 15 Bxh7+ Kh8 (15 ... Kxh7 16 Qh5+, 17 Qg4+ and 18 Rd3 wins; 15 ... Kg8 16 Qg4+ is similar) 16 Qh5 Rg8 17 Be4+ Kg7 18 Bxb7 with advantage to White, or 16 ...Kg7 17 Qg4+ Kh8 18 d5 (better than 18 Rd3 Qd5 19 Rh3 Qg5+ 20 Qxg5 fxg5 21 Be4+ and 21 Bxb7) and only then 19 Rd3, with Black's Qd5 and Qg5+ avoided. |

|
| Dec-18-22 | | jrredfield: I saw the first three plies with the two White sacs right away, leaving Black's K so vulnerable that White could afford to be behind in material. I guessed 15 ... Kxh7 but clearly Black saw the danger by then and didn't bite. A masterful attack by Vlastimil. |
|
| Dec-18-22 | | nalinw: First two moves are Tuesday or Wednesday - but anticipating the defensive resources via the d5 square make it a Sunday puzzle ..... |
|
| Dec-18-22 | | Mayankk: Black has left its King alone, marshalling its resources on Queenside in hopes of its own offensive. That usually means a vulnerable Kingside and White can force-open the pawn wall protecting the Black King via 14 Nf6+. It can't be refused and after 14 ... gxf6 15 Bxh7+ Kxf7 16 Qh5+ Kg8/Kg7 17 Qg4+ Kh8/Kh7 18 Rd3, Black can't protect against 19 Rh3#. That means 15 ... Kh8 16 Qh5 Kg7 17 Qg4+ Kh8 (since taking the poisoned Bishop only hastens mate as above). After this I would have likely gone stray via 18 Rd3 and hope for a mating attack via Rh3/Rg3 at some point. The subtle reason on why 18 d5 was better is beyond me. |

 | | An Englishman: Good Evening: The combination of 3...b6 and 5...dxe4 looks horrible, almost inviting the conflagration to come. Bit too easy for a Sunday, esp. as two variations seem to work. 5/7 this week. Flubbed Wednesday (really), flubbed Thursday, solved Saturday and Sunday. Might be my new normal. |
|
| Dec-18-22 | | Cheapo by the Dozen: The reason for 18 d5 is to deny the square to the black queen, and hence keep her away from g5. |

 | | agb2002: White has a bishop and a knight for the bishop pair. The black castle looks defenseless and White can attack with four pieces starting with 14.Nf6+ gxf6 15.Bxh7+: A) 15... Kxh7 16.Qh5+ Kg7(8) 17.Qg4+ Kh7 18.Rd3 Bxg2 19.Qxg2 e5 20.Rh3+ Qxh3 21.Qxh3+ wins decisive material. B) 15... Kg7 16.Qg4+ Kh8 (else 17.Rd3 as in A) 17.Rd3 B.1) 17... f5 18.Qh5
B.1.a) 18... Kg7 19.Rg3+ Kf6 20.Qg5#.
B.1.b) 18... f6 19.Bxf5+ Kg8 (19... Kg7 20.Qh7# or 20.Rg3#) 20.Rg3+ Qg7 21.Rxg7+ Kxg7 22.Qh7#. B.1.c) 18... Rfb8 19.Rg3 wins.
B.1.d) 18... Rg8 19.Rh3 Rg6 20.Bg8+ and mate in two. B.2) 17... Rg8 18.Bxg8 and mate soon.
B.3) 17... Qd5 18.Rh3 Qxg2 19.Be4+ Qxh3 20.Qxh3+ Kg7(8) 21.Qh7#. C) 15... Kh8 16.Qh5
C.1) 16... Kg7 17.Qg4+ transposes to B.
C.2) 16... Rg8 17.Be4+ Kg7 18.Bxb7 wins a pawn with the better position. C.3) 16... Rfb8 17.Be4+ Kg7(8) 18.Qh7+ Kf8 19.Bxb7 Rxb7 20.Qh8+ Ke7 21.Qxa8 wins decisive material. C.4) 16... Qd5 17.Bf5+ Kg7(8) 18.Qh7#. |

| | agb2002: It seems I underestimated the move ... Qd5. |
|
| Dec-18-22 | | faulty: masterclass. how to get attacked in French and commit an aesthetic suicide. maximum points for that |

| Dec-18-22 | | Allderdice83: <patzer2> After 18 Rd3 Qd5, I thought of 19 f4?? to stop Qg5+, but then realized that Black wins with Qxa2, threatening Qa1#:
20 Kd1 Qb1+ 21 Ke2 Qxh1 and it looks like White gets mated rather than Black; 22 Rg3?? Qe1+ 23. Kd3 Qd2+ 24. Kc4 Bd5+ 25. Kb5 a6+ 26. Ka4 b5#. Alternatively,
22 Qh4 Qxg2+ 23 Kd1 (Kd3 Qf3#) Qf1+ 24 Qe1 Qxe1# 22 Qg3 Qxg2+ 23 Qxg2 Bxg2 24 Rg3 and White is out of immediate danger but will be down a rook AND a bishop with no more threats themselves, or 22 Rd1 Qxg2+ with a similar result as above, or 22 Be4 Qe1+ 23 Kf3 Bxe4#
Also, after 19 ... Qxa2, 20 Ra3 Bxa3 21 bxa3 Qa1+ winning the other rook as well. It's amazing how much complexity there can be in a position. I probably wouldn't have found d5 myself or seen any danger after 18 Rd3 until I got hit with 18 ... Qd5!! |
