| May-13-14 | | TheBish: T Olsarova vs S Gvetadze, 2013 White to play (24.?) "Easy"
24. Rxh7+! Kxh7 25. Rd4 and Black can't stop 26. Rh4#. Pretty good Tuesday problem. |
|
| May-13-14 | | agb2002: White is a pawn down.
Black threatens 24... fxe5.
Pattern recognition finds 24.Rxh7+ Kxh7 25.Rd4 Bf8 26.Rh4+ Bh6 27.Rxh6#. |
|
| May-13-14 | | hoodrobin: <Phony Benoni: we don't need to follow up with a queen check, since she's fine where she is.>
So many positions (and problems!) are difficult just because we think we should do the right (usual) thing! |
|
| May-13-14 | | therevolver17: 24.Rxh7+ Kxh7 25.Rd4 and black is going to be checkmated in the next move (26. Rh4#). |

| May-13-14 | | morfishine: 24.Rxh7+ Kxh7 25.Rd4

| May-13-14 | | Herma48852: 24. Rxh7+ Kxh7 25. Rd4! with no defense against 26. Rh4 and mate. I wondered if the rook lift could come first but it looks like 24. Rd4 Nf8! saves the day for black. |

| May-13-14 | | patzer2: Helping prepare today's Tuesday 24. Rxh7+! Kxh7 25. Rd4 Bf8 26. Rh4+ Bh6 27. Rxh6# (mate-in-three) combination is the pawn sac 21. f5!  to  (diagram below).

| May-13-14 | | Nick46: I wish to thank <Herma48852> and to disagree with <diagonalley>. |
|
| May-13-14 | | zb2cr: 24. Rxh7+, Kxh7; 25. Rd4, Bf8; 26. Rh4+, Bh6; 27. Rxh6#. The Bishop's long-range support of h6 makes this possible. |
|
| May-13-14 | | Chess Dad: <Rxh7+ seemed like the obvious first move, but I was then looking for queen checks or exf6 and getting nowhere. I completely missed the rook lift.>
Same here. I knew the Rd1 was going to be important, and I saw the route, but I was looking at it with the mindset that my second move was Qh5+ and didn't see leaving the Q on the g file was even better. <So many positions (and problems!) are difficult just because we think we should do the right (usual) thing!> And that's exactly how the problem became harder for me. |
|
| May-13-14 | | Marmot PFL: I saw this sac quickly, having been on the receiving end in a few Sicilians. Black made several mistakes, 20...d5 (Bxf3) and 21...Bb4 (what's the point?) among the worst. |
|
| May-13-14 | | patzer2: The problem became harder for me because after 24. Rxh7+ Kxh7, I incorrectly visualizing the King as being on h8 (instead of h7) for White's 25th turn (position below)
click for larger viewWhite still wins in this position with 25. Rd4!
However it's no longer the simple mate-in-three (from the actual game position with the King on h7) with 24. Rxh7+! Kxh7 25. Rd4 Bf8 26. Rh4+ Bh6 27. Rxh6#. Now with the King wrongly visualized on h8 (diagram above) I had to calculate the mate-in-seven 25.Rd4 Nf8 26.Rh4+ Nh7 27.exf6 (27...Rg8 28. Rxh7+ Kxh7 29. Qh4+ Kg6 30. Qg5+ Kh7 31. Qh6#) 27...Bf8 28.Qh3 Bh6 29.Rxh6 Qxb2 30.Rxh7+ Kg8 31.Rh8#. P.S.: Lessons Learned:
1. Correct perception of reality makes Chess (and life) easier. 2. Incorrect perception of reality makes Chess (and life) harder. |

|
| May-13-14 | | kevin86: The second rook enters the fray and will deliver the knockout blow. I was thinking along the lines of mating with the bishops and queen, but the text is far better. |
|
| May-13-14 | | David2009: I went for 24.Rd4? which allows Black to struggle on material down after 24...Nf8
25.Rxb4 Qxb4 26.Rxb4 Rxb4. The sacrifice is much better. |

|
| May-13-14 | | CC0112358: To <PiinedPiece> and to <Marmot PFL> points, Sopio worked very hard to loose this game. After 20. e5 she decided to go out to lunch. |
|
| May-13-14 | | BOSTER: < David2009 :I went for 24.Rd4?>. Money in the morning, chairs in the evening. |
|
| May-13-14 | | Patriot: I found the right sequence, but this is a lot tougher than the usual Tuesday. I was distracted by 25.Qh4+ Kg8 26.Bh6 Nf8 27.Qxf6 Bf8. |
|
| May-13-14 | | PJs Studio: This one took me an extra half minute to see 24.Rxh7+ certainly works better than 24.Rd4 as 24...Nf8 holds for a couple of extra moves. |

 | | offramp: <goldfarbdj: ... I completely missed the rook lift.> Did you know that there is a real rook lift in the Tower of London? It is very easy to miss, as it is a small dumb waiter-style contraption. The rooks use it to reach the top of the Bloody Tower. Their wings are clipped, so they cannot fly and have to use the lift. There is also a short escalator for differently-abled rooks who cannot use the lift. |

| | offramp: The rooks are taught to use the lift by means of a man's hand inside a black sock puppet who teaches them which numbers to press when they are rooklets. Correct presses by the rooklet are rewarded by real human flesh imported from the far east. Incorrect presses result in a powerful electric chock. |
