| Apr-05-10 | | A Karpov Fan: Monday is here and as usual my ELO is at its peak somewhere around 2600 and a few seconds is all I need to solve the puzzle...but no doubt as the stresses and strains of the week take their toll as usual I will be dropping down to 1100 ELO by Friday and have given up altogether by Sunday. |
|
| Apr-05-10 | | cocker: If 30 ♔h4, I prefer 30 ... ♗f6+ 31 g5 ♖xf2 with a simple mate. |
|
| Apr-05-10 | | cocker: Or win of queen! |
|
| Apr-05-10 | | Shah Mat: took me about a minute or so but as soon as i saw it i saw the whole thing. |
|
| Apr-05-10 | | goodevans: After <30 Kh4> my choice would be the simple <30 ... Rxf2>. Looking back, <26 Kg2> looks like a horrible blunder to me. What's wrong with the simple <26 Rf1>? Now black has all four (!!) of his pieces en prise and I can't see how he would avoid losing material. |
|
| Apr-05-10 | | nuwanda:
i spotted 29...Qf3+ rather quickly, with the thoughts, white cannot take and if 30.Kh4 then, if nothing better, 30...Rxf2 wins easily. here i stopped.and indeed there is something better, the starting position is mate in 6 as <TheBish> pointed out ... |

 | | offramp: 27..Ra2+ is a very good move; very easy to miss. Black's finish is stunning. |
|
| Apr-05-10 | | goodevans: <nuwanda> Yep, 30 ... Rxf2 is at least one move slower than the immediate 30 ... g5+. |
|
| Apr-05-10 | | goodevans: <offramp: ... Black's finish is stunning.> I still reckon that the whole attack is flawed and that white only lost because of the <27 Kg2> blunder. |
|
| Apr-05-10 | | WhenHarryMetSally: Quite tricky actually:
I am thinking something like:
29.....Qf3+,
30. RxQ, Rxh2++
So I think
29.....Qf3+,
30. Kh4, Bf6+
31. Ph5, Qh5#
A piece can also easily be won with:
29.....Qf3+,
30. Kh4, Rxf2
Time to check |
|
| Apr-05-10 | | wordfunph: 29...Qf3+ and if R takes Q, mate by 30....Rxh2#
29...Qf3+ 30.Kh4 Qxg4# |
|
| Apr-05-10 | | jussu: Very easy? Well, maybe, but I'm evidently missing something. 29... Qf3+ 30. Kh4 is obvious, probably every move wins but it still gets a bit messy. 30... Rxf2 31. Nxe5 Rxh2+ 32. Kg5 h6+ 33. Kxg6 now there must be a mate but where? Or maybe 30... g5+ 31. Bxg5 Qxd3 32. Nxe5, must be winning alright but if this is "very easy" then I am getting too old for chess. |
|
| Apr-05-10 | | jussu: Oh dear, 29... Qf3+ 30. Kh4 g5+ 31. Bxg5 Qxf2+ of course. I really am getting too old for chess. |
|
| Apr-05-10 | | jussu: (or 31. Kxg5 Bf6+ and 32... Qh3#) |
|
| Apr-05-10 | | karnak64: Hmm, this Somacarana chap goes by one name. Chess player, or Brazilian soccer star? (Okay, I read his page, he lived in Calcutta and no one seems to know much about him). |
|
| Apr-05-10 | | johnlspouge: Monday (Very Easy)
Cochrane vs Somacarana, 1856 (29...?) Black to play and win.
Material: B for N. The White Kh3 has 1 legal move, h4. The White Rf2 has the absolute burden of preventing Ra2xh2#, suggesting that Black should overload Rf2. Candidates (29...): Qf3+
29…Qf3+
(1) White cannot accept the sacrifice:
30.Rxf3 Rxh2#
(2) 30.Kh4
I went for <30…Bf6+>, which (like everyone else’s move) leads to an overwhelming win for Black. As <TheBish> points out, the puzzle position is a forced mate. |
|
| Apr-05-10 | | YetAnotherAmateur: I believe <agb2002> pointed towards another win. The approach I took that appears to work:
29. ... Qf3+
30. Kh4 (if Rxf3, Rxh2#) g5+
A)
31. Kh5 Qh3+
32. Kxg5 h6+
33. Kg6 Be8+
34. Rf7 Bxf7#
B)
31. Kxg5 Bf6+
32. Kh6 Qh3#
C)
31. Bxg5 Qxf2+
C1)
32. Kh3 Qxh2#
C2)
32. Kh5 Be8+
33. Qg6 Bxg6+ (this move can be skipped, it just delays things a bit)
34. Kh6 Bg7#
C3)
32. Qg3 Bxg3+
33. Kh5 (if hxg3, Qh2#) Qxh2+
34. Bh4 Qxh4#
Which is a long way of saying "forced mate in 5". |
|
| Apr-05-10 | | remolino: 29...Qf3+ |
|
| Apr-05-10 | | desiobu: For some reason I thought it was white to play, and was trying to defend against the coming ...Qf3+. The simple Nxe5 probably does it. Shows the power of a tempo. |
|
| Apr-05-10 | | sethoflagos: <goodevans: <snip>, <26 Kg2> looks like a horrible blunder to me. What's wrong with the simple <26 Rf1>?> Not sure. 27. Rf1 is safe enough - after 27. ... Rxf1 28. Qxf1 it looks drawish. I think white was expecting 27. Kg2 Qb5
28. Nxe5 Qxd3
29. Nxd3 which leaves white comfortably ahead.
Even better for white is
27. Kg2 Ra2+
28. Bd2 Bb5
29. Nxb6 Bxd3
30. Rxd3
28. Rf2 was the real blunder |

 | | gawain: Nifty position! Qf3+ wins by deflecting the rook and allowing Rxh2#. It's nice how the g4 pawn blocks the King's escape and how the same Bishop that is supporting the rook at h2 also covers the g3 square. The setup pleases me a lot. |
|
| Apr-05-10 | | kevin86: Black offers his queen-if accepted,the result is immediate mate;if declined,the game tumbles like dice. |
|
| Apr-05-10 | | thegoodanarchist: <karnak64: Hmm, this Somacarana chap goes by one name. Chess player, or Brazilian soccer star?> or both??? :) |
|
| Apr-05-10 | | thegoodanarchist: <jussu: Oh dear, 29... Qf3+ 30. Kh4 g5+ 31. Bxg5 Qxf2+ of course. I really am getting too old for chess.> How about 30. Kh4 Bf6+ 31. g5 e5 32. Qf5 (only move) Bxf5# |
|
| Apr-05-10 | | goodevans: <sethoflagos: ... 27. Rf1 is safe enough - after 27. ... Rxf1 28. Qxf1 it looks drawish.> But 27 Rf1 Rxf1+ 28 Kxf1 still leaves white with three pieces en prise. Surely this must be winning? <Even better for white is
27. Kg2 Ra2+
28. Bd2 Bb5
29. Nxb6 Bxd3
30. Rxd3>
So by my reckoning white missed two winning opportunties. |
