| May-19-11 | | sevenseaman: <Ghuzultyy> Interesting analysis after 37... NXd5. |
|
| May-19-11 | | dzechiel: Looked at this briefly last night. I only considered forcing moves (following my own advice) and therefore overlooked b4! as the saving move. I like to think that if I was in the game, I would have considered b4, but can't promise it. |
|
| May-19-11 | | psmith: Found b4 only after spending far too much time on R checks. |
|
| May-19-11 | | gofer: <Ghuzultyy> One line I liked was one where white promotes and dies... <35 b4 Rc3>
<36 g7 Rxa3>
<37 g8=Q ...>
<GOOT>
<37 ... Rxb4+>
<38 Kc1 Rc3+>
<39 Kd2 Rc2+>
<40 Kxe3 Rb3+>
<41 Kd4 Rd2+>
<42 Kc4 b5#>

| May-19-11 | | cyclon: 35.b4, cufflinks. |
|
| May-19-11 | | ZUGZWANG67: White has 2 pawns for the piece, these pawns are passed and the one at g6 is very dangerous (R behind p). Black has no piece to fight it. But Black has a possibility for a perpetual. Before cashing on his advantages White must make sure that the game won't end in a draw. At 1st I thought that 35.Rf7+ Ke5 36.Rg5+ Kd4 37.Rf4+ Kd3 (the R needs to remain protected in (!)case the N has to go after the g6-pawn) 38.Rb4 should win but 38...Rxd5! 39 Rxd5 Nxd5 is not that obvious. So I found out that I needed more candidates. As I was going from candidate to candidate I could see that it was far more complicated (to me!) than I thought. I had 35.Rf7+, 35.Rg5+ and finally 35.Ka1(!!!)
Is it possible 35.Ka1 to be the move? In fact without a check ...Rbxb2 is not a so strong defensive move, after all. And ...Rcxb2 is not dangerous: the Rg1 covers b1. However the problem with 35.Ka1 is that it is a quiet move. This allows Black to do something unless 35.Ka1 has more than just removing the 38...Rxd5 option from Black's hands and preventing mate once the Rg1 has left the back rank (35.Ka1 Rbxb2 36.Rf7+ Ke5 37.Rg5+ Kd4 38. Rf4+ Kd3 39.Rb4; 35...Rcxb2 36.Rf7+ Ke5 37.Rg5+ Kd4 38. Rf4+ Kd3 39.Rb4!). But does not Black have anything else than just 35...Rxb2? There,s 35...Rc8 36.g7 Rg8 37.Rg8. This earns White a R for p or a Q for a R+p. That's all I have. Rather tough for a thursday. Either I'm right on the spot or it will be shame on me; I missed an obvious one. ---------
What? |

| May-19-11 | | ZUGZWANG67: Ok. Let's call Rybka for help. I just can't believe that. |
|
| May-19-11 | | chesskidnate: <Zugzwang67> didn't check with a computer but in your 35.Ka1 Rbxb2 line what about 38... Kc3 because if 39.Rb4 Rxb4 40. axb4 Rb2! threatens 41...Nc2# which I think forces white to sacrifice his rook and be dead lost |

Kc3 because if 39.Rb4 Rxb4 40. axb4 Rb2! threatens 41...Nc2# which I think forces white to sacrifice his rook and be dead lost> You are right. My analysis is flawed. And worse than 39...Rxb4, Black has 39...Rc1 mate. Peace! |
|
| May-19-11 | | ZUGZWANG67: <<AliTervia>: What about 35 Ka1? Not foolproof but it slows black down. Over the board, 35......Rbxb2 still looks good, but allows 36. Rf7+ Ke5
37. Rg5+ Kd4
38. Rf4+ Kd3
39. Rb4
interrupting the mate or perpetual check possibilities. White's pawn now has a chance to promote, and material and attacking options even out. White might have to take a draw but this seems not too hard to work out and gives a fighting chance?>38...Kc3 (<chesskidnate>) 39.Rb4 Rc1 mate. |
|
| May-19-11 | | ZUGZWANG67: 35.b4. Too easy. Missed it.
Surprising that after spending soooo long trying to avoid a perpetual, this move never received the consideration it deserves in my analysis. I saw it, of course. But no more than that! Sigh! |
|
| May-19-11 | | lzromeu: 35b4 is the only move I can see.
I'm weak player, this time I had lucky, but this move is the more natural. |
|
| May-19-11 | | tacticalmonster: Missed it. I only had the idea of playing 35 Rf7+ perpetual check or 35 Rf7+ Ke5 36 Rg5+ Kd4 37 Rg4+ Kd3 38 Rb4 Rxd5 39 Rxd5 Nxd5 40 Rg4 Nf6 41 g7 Ng8  |
|
| May-19-11 | | alachabre: White has the move, two passed pawns, and a dire threat against b2. What to do, what to do? Nabbing the knight is no good, because Black at the very least draws after Rbxb2+. Let's see if chasing the king around does any good, the pawns seem well placed for the adventure: 35. Rf7+ Ke5
36. Rg6+ Kd4 - interposing the knight here only loses it with check. 37. Rf4+ Kd3 and the chasing is over, but White has the resource: 38. Rb4, blocking the check on b2 and now it seems the g pawn is free and clear to advance and queen. |
|
| May-19-11 | | alachabre: Ah well, didn't go deep enough. |

 | | Breunor: Can any one help with the following:
Why can't black take the rook (K x h8) on move 27?
Thanks,
Breunor |
|
| May-19-11 | | avidfan: 27...Kxh8 28.Qh2+ Kg7 29.Qh7+ Kf6 30.Qf7+ Ke5 31.Qe6+ Kf4 32.Qe4+ Kg3 33.Rd2 giving White a fairly good position, still with a passed pawn at g6

| May-19-11 | | mccarthpm: b4 try Rc3 g7 37.Nc4 |
|
| May-19-11 | | t rador: C)<38.Rg5+ Ke6!>
A big mistake would be to play like this 38...Kd4?? 39.Rxd5+! Rxd5 40.g8=QAlso note that after 38...Ke6, white can't play 39.Rxd5 because black wins after 39...Rxd5 40.g8=Q Rd1# <39.Rg6+ Ke5 40.Rg5+> White draws the game. A good looking move, 36.Rf7+, ended as a disaster for white. Hi maybe you miss these sir,
<38.Rg5+ Ke6!>
39. Rg6+, can't capture the R at f7, g8(Q)+ winning.
39. ... Ke5
40. Rc7! winning for white.
or maybe a miss something also. |

| May-20-11 | | sevenseaman: Guys, no one seems to have attempted my 8-move mate puzzle. Its obvious people shun complicated and long puzzles. I gave it as it plays like a humdinger and only the two opposing royals move. Disappointed but the sol is; 1. Qa5+ Kc6 2. Qc7+ kd5 3. Qd7+ Ke4 4. Qc6+ Kf5 5. Qe6+ Kg5 6. Qh6+ Kh4 7. Qf4+ Kh3 8. Qg3# The final position;

| May-20-11 | | David2009: K Akshayraj vs Le Quang Liem, 2008 White 35? I glanced at the puzzle position

yesterday and fell into the same trap as <tacticalmonster: Missed it. I only had the idea of playing 35 Rf7+ perpetual check or 35 Rf7+ Ke5 36 Rg5+ Kd4 37 Rg4+ Kd3 38 Rb4 Rxd5 39 Rxd5 Nxd5 40 Rg4 Nf6 41 g7 Ng8 - +> but didn't have time to post my wrong "solution". In <tacticalmonster>'s line Black has even better than 39...Nd5 viz 39...a3!

GOOT! since 40 bxa3? loses immediately to 40...Nd5 etc. White did well to avoid this in the real game. Curious that I never considered 35 b4! - at least I am in good company. Crafty End Game Trainer link to the puzzle position: http://www.chessvideos.tv/endgame-t... |

| May-20-11 | | avidfan: Further analysis from previous position after 33.Rd2 then 33...Qb6 wins for Black because if 34.c3 Rxc3
and White still cannot check the Black king because g2 and g4 are guarded by the N/e3. If 33.Rh1 Rxb2+ ! 34.Kxb2 Qb5+ wins since 35.Kc1 Rxc2# or 35.Ka1 Nxc2+ 36.Ka2 Qb3# So the conclusion is that 27...Kxh8 was quite playable despite the forced sequence of moves by White chasing the king to g3. But if 32...Kg5? White will force mate after 33.Rg1+ Kh6 34.Qh4+ Kg7 35.Qh7+ Kf6 37.Qf7+ Ke5 38.Qe6+ Kf4 (or Kd4) 39.Qe4# |

| | Breunor: Thanks Avidfan! I didn't see the combo (whether it wins or not!) |
|
| May-21-11 | | kevin86: Mist it! White was able to force a draw and avoid being mated by the rooks. No win,just a save(d draw) |
