 | | al wazir: I didn't see how white could avoid a perpetual after 30. Rxe5, so I went with 30. Rd8, which is at least interesting: 30...Qb5 31. R1d7! Nxd7 32. Rxe8+ Kf7 33. Rh8, and now I don't know what happens. (Maybe 33. Qe3 Ne5 34. Rc8, with the threat of 35. f4, is better.) |
|
| May-31-13 | | stacase: White trades the Rook for a Knight and the move. |
|
| May-31-13 | | mistreaver: Friday.White to play. Difficult. 30?
Rarely has the right idea struck me right when i opened chessgames.com.
30 Rxe5!!
Black has two ways to recapture:
A)
30 ... Rxe5
31 Rd8+ Kf7
32 Qxh7+ Ke6
33 Qd7 mate
B)
30... fxe5
31 Rd7 Qb1+
32 Kg2 Qe4+
33 f3 Qxe2+
34 Kh3 Qf1+
35 Kh4
and white will win as black will run out of checks.
TIme to check.
--------------
For some reason i missed that black can cover with Re7 altough it is obvious that after Rd8+ White wins quite easily as black's king is too exposed. Fritz gave green light to my B) line since black doesn't have perpetual |

|
| May-31-13 | | morfishine: Forcing is <30.Rxe5 fxe5 31.Rd7 Re7 32.Rd8+ Kf7 33.Qxh7+ Kf6 34.Qh8+ Kg5> However, <35.e4+> looks stronger than 35.h4+ due to the exposed position of the Black Queen |
|
| May-31-13 | | lost in space: I saw the first few moves, but I was not sure if white can avoid a perp. |

| May-31-13 | | YetAnotherAmateur: I have to say, starting at 36 or so it sure seems like somebody was in a hurry to get to move 40. |
|
| May-31-13 | | Patriot: I think 30.Rxe5 is best.
30...fxe5 (30...Rxe5 31.Rd8+ Kf7 32.Qxh7+ Ke6 33.Qd7#) 31.Rd7 Qb1+ 32.Kg2 Qe4+ 33.f3 Qxe2+ 34.Kh3 Qf1+ 35.Kh4 Qc4+ 36.g4  One of the points behind 30.Rxe5 over 30.Rd7 Nxd7 31.Rxd7 is after 33...Qxe2+ 34.Kh3 Qe6+ wins! |
|
| May-31-13 | | Patriot: I completely missed the game line, 31...Re7 which is far more difficult to win. |
|
| May-31-13 | | kevin86: It looks like we will have a king chase. |

 | | LIFE Master AJ: I was just about stumped on this one. After a fairly lengthy "think" ... I went for 30.RxN/e5!?, fxe5; (Taking with the Rook looks markedly worse.)
31.Rd7, Re7; 32.Rf8+, Kh7; 33.QxP/h7+. However, no CLEAR forced win is in sight, one mis-step and White could be in trouble. I don't know who rates these things, (They definitely blew it here.); but this could have been a Sunday problem, IMO. Time to look and see what I missed. |
|
May-31-13
| | LIFE Master AJ: Should have been 32.Rd8+. |
|
May-31-13
| | LIFE Master AJ: Apparently, I was not far wrong, Wjite eventually won, but it took more than 15+ moves to decide the game in his favor. |
|
May-31-13
| | LIFE Master AJ: I also looked at 30.Rd8, according to Fritz 13, it may also win. |
|
| May-31-13 | | Patriot: <LMAJ> I agree that calculating it out to a win after 31...Re7 is very difficult. But I always wonder how far really something like that needs to be calculated during a game, when time is available. White is clearly getting the initiative and material is even after 32.Rd8+ Kf7 33.Qxh7+. Black has the dangerous passers on the a and b-files but they are far from promotion. So, even with enough time on the clock, is it a good practical decision to try and calculate everything out? I'm not sure here. It seems that usually it's only necessary if white sacrificed a lot of material, for example, and must walk a tight-rope to win. Here he doesn't seem to be risking much, except the fact he gave the exchange back instead of trading down when ahead with 30.Rd8 (the move you also considered). |

| May-31-13 | | Patriot: <<Moonwalker>: Saw the first two moves pretty much straight away. How far does one need to go to claim credit?> That's a key question and it depends on who you ask. It also depends on your goal--to become a better puzzle-solver or become a better analyst. Those are two very different goals. Personally I would rather become a better analyst to help me become a better player! In the case of becoming a better player, it's very important to know when to start (or stop) analyzing because time is precious. A puzzle-solver can work on it all day if he so chooses and come up with some great lines. I think one of the keys to becoming a better analyst is making sure you have considered all the critical moves. For example, I wondered what the difference is between 30.Rxe5 and 30.Rd7. The difference is that white will have to accept a draw after 30...Nxd7 31.Rxd7 Qb1+ 32.Kg2 Qe4+ since 33.Kh3 Qe6+ loses the rook (or 33.f3 Qxe2+ 34.Kh3? Qe6+  ). But after 30.Rxe5 fxe5 31.Rd7 Qb1+ 32.Kg2 Qe4+ 33.f3 Qxe2+ 34.Kh3, 34...Qe6+ is no longer available to black since there is now a pawn on e5! So then 34...Qf1+ 35.Kh4 Qc4+ 36.g4 and black has run out of viable options since white is threatening mate next move. |

| May-31-13 | | anandrulez: Perpetual (or lack thereof) is the only reason its a 3 star I think . Interesting how white king can escape ! |

| | LIFE Master AJ: <Patriot> Excellent job!!! ... as usual. |

| May-31-13 | | ZZpatzer: Play this position against crafty here: http://www.chessvideos.tv/endgame-t... |
|
| May-31-13 | | morfishine: <Life Master AJ> In my earlier post, after 30.Rxe5 fxe5 31.Rd7 Re7 32.Rd8+ Kf7
33.Qxh7+ Kf6 34.Qh8+ Kg5 I felt White erred with 35.h4+ when <35.f4+> was better I originally typed 35.e4+ :( |
|
| Jun-03-13 | | Moonwalker: <Patriot> I agree, it's entirely objective-based. Personally, I don't like to consider every possible line and simply hope to identify the theme and key moves! |

| | LIFE Master AJ: <Patriot> makes a very good point, i.e. is it better to be an analyst or a puzzle solver? I think the answer depends on your goals. My goal is to do both. When I am here, I am a puzzle solver. When I am at a tournament, I want to be a good and efficient analyst. In other words, (IOW); I want to look at as many lines as I can, analyze them quickly and as deeply as the time limit will allow. Thanks to the sudden death time controls, (of modern tournaments); I think that I must be much more disciplined at the board. Gone are the days of 45 or 50 moves in 2.5 hours ... and I could often spend 30 minutes (or more!) looking at the craziest of sacrifices ... whether I would play them or not was not the question, it was fun just to spend time investigating the coils of the labyrinth. (Just for the heck of it.) Nowadays, I rarely do that. However, when I am here, and time allows, then I often enjoy looking at a complicated puzzle for as long as I want ... the joy of watching the pieces dance in your head. |
