| May-16-15 | | DanielHoseano: 21. Bc4 Is that good? |
|
| May-16-15 | | Cheapo by the Dozen: The basic idea is
21 Rxh7+ Kxh7
22 Qf7+ Bg7
23 Bd3
and mate quickly follows, due mainly to the threat of Rh1 and secondarily to the threat of Qxg6. A much better try at defending for Black is
21 Rxh7+ Kxh7
22 Qf7+ Kh6
23 Bd3 Rg8
White now needs to do something about the c1-h6 diagonal. So let's continue with 24 f4 ef
25 g5+ Kxg5
26 Rg1+ Kh6 (to avert Qh7+)
27 Rxg6+
and mate next.
OK. This is hardly an exhaustive analysis, but if I got this far I'd be willing to take my shot at this line over the board. |
|
| May-16-15 | | Cheapo by the Dozen: Looks like the Saturday puzzle that I got was accessible to unusually many other folks as well. But yes -- most of us, despite seeing the issues on the c1-h6 diagonal, seem to have overlooked <JimFromProvidence>'s defense. |
|
| May-16-15 | | wooden nickel: Black must have seen trouble coming after 20.e5!, maybe that's why he didn't play 20... Bxe5 (instead of dxe5), it loses in a similar manner.
... also tried
21.Bc4 Rxc4 22.Rxh7+ Kxh7 23.Qf7+

but Black can escape to 23... Kh6! |
|
| May-16-15 | | DanielHoseano: Oh thanks wooden nickel |
|
| May-16-15 | | patzer2: Here's my look at the game and the Saturday puzzle (21?) with Fritz: <18. Bxf6 Bxf6> Better for Black is 18... Bxe4! 19. fxe4 Bxf6 20. Qd5+ =. <19. Qxd5+ Kg7 20. e5 dxe5?> The decisive error. Instead, Black can hold on with only a small White edge after 20... Bxe5 21. Bd3 Rh8 22. Kb1 Qa4 23. Qe6 Qf4 24. Qxe7+ Qf7 25. Qh4  . <21. Rxh7+!!> This solves today's Saturday puzzle. <21...Kxh7 22. Qf7+ Kh6 23. Bd3 Rg8> Got this far with my Saturday puzzle solution try, but calculated a different follow-up than the game continuation. <24. f4!> Fritz indicates this is strongest, forcing mate-in-seven. My planned follow-up was 24. Rh1+ Kg5 25. Qh7  , which Fritz shows forcing mate-in-18. <24...exf4>
If 24...Bh4, then 25. g5+ Bxg5 (25... Kh5 26. Be2#) 26. Rh1+ Bh4 27. Rxh4#. <25. g5+ Kxg5>
If 25... Kh5, then 26. Qh7+ Kg4 27. Rg1+ Kf3 28. Qh3+ Kf2 29. Rf1#. <26. Rg1+ Kh6 27.Rxg6+ 1-0> Black resigns in lieu of 27...Rxg6 28.Qxg6# or 27...Kh5 28.Qh7#. |
|
| May-16-15 | | HaydenB: I didn't find this very difficult at all. I saw the rook sac theme on h7 followed by the Queen to f7 in less than 10 seconds. I was hoping however that the Bishop could find his way to c4, a la Kurt Richter, but after a few more seconds realized the Queen and Rook could not mate by themselves. |
|
May-16-15
 | | Penguincw: I got 21.Rxh7+ Kxh7 22.Qf7+ (any) 23.Bd3, and eventually got the idea of bringing the rook over to the kingside. |
|
| May-16-15 | | gars: I completely agree with <HaydenB>. I did not solve it by I saw five of the seven moves of the combination and I am a weak player. |
|
| May-16-15 | | morfishine: I figured after <21.Rxh7+> Black is toast after 21...Kxh7 22.Qf7+ since White has 23.Bd3 followed by 24.Rh1+ ***** |
|
| May-16-15 | | paavoh: Yes, I agree: a bit easy for a Saturday. Rxh7+, Qf7 is standard, so finding a simple Bd3 to attack g6 and open the route for R to h1 was sufficient. |
|
| May-16-15 | | Tiggler: I did not see 24.f4, which is a brilliant way to finish, but 24.Rh1+ also wins. |
|
May-16-15
 | | Sally Simpson: A success! went with the Bg5+ line defended g6 with Rb6 but everything works and I got the key moves. Those that say today was easy....have you considered that you may be getting better! |
|
| May-16-15 | | Tiggler: <patzer2> Did Fritz not see that 23. ..Bg5+ holds out longer? There is no forced mate then, but a Q+4p vs R+4p ending. |
|
| May-16-15 | | kevin86: Even for a Saturday, the key was obviously. When the king is trapped along the side, an early demise for black is inevitable. |
|
May-16-15
 | | Jimfromprovidence: <Sally Simpson> <...went with the Bg5+ line defended g6 with Rb6...> Thanks for pointing that out. I assume you meant 23...Bg5+ 24 Kb1 Rb6. 
click for larger viewI did not think of 24...Rb6. Unfortunately, it is now a forced mate for white. But it made me figure out why 24...Qb6 is the only playable move here. This is a richer puzzle than some imagined. |

| May-16-15 | | M.Hassan: "Very Difficult"
White to play 21.?
White is a pawn down.
The open h file and posssibility of a Queen check suggests a Rook sac.: 21.Rxh7+ Kxh7(forced if not:...Kf8 22.Qf7#)
22.Qf7+
A)
22..........Kh8
23.Bd3 Bg7
24.Rh1+ Bh6
25.Rxh6#
B)
22...........Kh6
23.Bd3 Rg8
24.g5+!
B.1)
24...........Bxg5
25.Rh1+ Bh4
26.Rxh4+ Kg5
27.Rg4+ Kh5
28>Bxh6+ Rxh6
29.Qxh6#
B.2)
24...........Kxg5
Looks like in this line the King can run away. I must have overlooked pushing the g pawn ahead, apparently first f pawn should have been pushed. I probably give myself 50% credit!! |
|
| May-16-15 | | Longview: I thought I needed to join the two white rooks before I did the Rxh7+ sac. I wanted to attack on the h file. I did not see, the concept, method or need to remove the pawns from the g file. My move was B-d3 but I thought the reply would be R-h8 and I was stuck on how to get the second rook involved. As usual, part of the angle. I am starting to think I am a one eyed drone. Good vision but no depth perception. |

| May-16-15 | | patzer2: <Tiggler> Thanks for suggesting a look at 23...Bg5+ with Fritz. I confess I didn't run the program on that move, since 23...Rg8 was played in the game and seemed a natural, intuitive human response. P.S.: Fritz confirms the Houdini assessment that 23...Bg5+ reduces to a won Queen & pawns versus two Rooks & pawns middle game. Fritz 12 gives 23... Bg5+ 24. Kb1 Qb6 25. Rh1+ Bh4 26. Bxg6 Qxg6 27. Rxh4+ Kg5 28. Rh5+ Qxh5 29. Qf5+ Kh4 30. gxh5 Kg3 31. h6 (+3.81 @ 17/41 depth). |

| May-16-15 | | agb2002: White is one pawn down.
The first idea that comes to mind is 21.Rxh7+ Kxh7 (21... Kf8 22.Qf7#) 22.Qf7+ Kh6 (22... Bg7 or 22... Kh8 23.Bd3 and mate soon) 23.Bd3 A) 23... Bg5+ 24.Kb1
A.1) 24... Rg8 25.Rh1+ Bh4 26.Rxh4+ (or 26.Qxe7 Qe1+ (26... g5 27.Qh7#) 27.Rxe1 Bxe1 28.Qxe5 + - [Q+2P vs 2R]) 26... Kg5 27.Qxe7+ Kf4 28.Qf6+ with compensation for the exchange looks very good. For example, 28... Kg3 29.Rh1 Qc7 30.Qh4+ and mate soon. A.2) 24... Qb6 25.Rh1+ Bh4 26.Qxe7 seems to win. It looks more complicated 26.Rxh4+ Kg5 27.Qxe7+ Kf4 (27... Qf6 28.f4+ exf4 29.Rh5+ Kxg4 (29... gxh5 30.Qxh5#) 30.Qxf6 + -). B) 23... Rg8 24.f4 exf4 (24... Bh4 25.Rh1 g5 26.Qh7#) 25.Rh1+ Kg5 (25... Bh4 26.Rxh4+ Kg5 27.Qxe7#) 26.Qh7 (26.Rh5+ gxh5 27.Qxh5# is very nice but Black can play 26... Kxg4) 26... f3 (26... Kxg4 27.Qh3+ Kg5 28.Qh4#; 26... Rh8 27.Qxg6#) 27.Qh6+ Kxg4 28.Rg1#. C) 23... Kg5 24.f4+ looks promising. For example, 24... Kxf4 25.Qxg6 Rg8 26.Qf5+ Ke3 27.Rf1 with the double threat 28.Qe4# and 28.Qf2#. |
