|Mar-30-07|| ||Eurotrash: yeah, I also got it right away. very easy for a friday. Normally I'm struggling very much by friday.|
|Mar-30-07|| ||Ashram64: Nd5, Rxe6+ w/ queen pinned, and Rxc8 are ideas for the white.|
|Mar-30-07|| ||Silverstrike: <al wazir> That's the line I got.|
|Mar-30-07|| ||Simplification: CG missed the pun? Da Vas iesi! - u? Surely it's gone a be a tough one tomorrow?|
|Mar-30-07|| ||mkrk17: I too got the line as <al wazir>. Although it seems to be winning for white, it is not as good as the line played in the game|
|Mar-30-07|| ||BabalooMoon: OMG I got a Friday. Fritz 5 goes for 31.Rxd7+ whilst Fritz 9 prefers 31.Rc8+|
|Mar-30-07|| ||uuft: 5/5. What gives?|
|Mar-30-07|| ||Tactic101: Same with Manic. Dash. The line played in the game was much better. Nd5 is the easy move to find, but the Rxd6 followed with Rc8+ is much stronger. Nuts.|
|Mar-30-07|| ||euripides: <29. Nd5 exd5 30. Rf8+ Rxf8 31. Rxc8+ Kxc8 32. Qxe7> is interesting. |

Black can play 32...Rf1+ 33.Ka2 Rbf3, or 32...Rbf3, or perhaps 32...Rf1+ 33.Ka2 Re3 pinning the e pawn when White has no check to break the pin, or 32..Rf2 angling for a perpetual.
In the long run Black can try to double his rooks on the h file or keep attacking the queen. If White plays exd5, a set up with rooks on f7 and f6 will stop White forming a second passed pawn, but then White may be able to push the h pawn. But after 32...Rf1+ 33.Ka2 Re3 I don't see a way for white to preserve the e pawn, though there may be a tactic somewhere to exploit the unprotected rooks.
Not sure if this is winning for White.
|Mar-30-07|| ||Bashful Bob: Hurra! I solved it in 30 seconds, that has never happened before on a friday!|
|Mar-30-07|| ||goodevans: Not sure why this is a Friday puzzle. Black's moves all seem pretty much forced, which isn't usual for this late in the week.|
I thought yesterday's was a bit easy too. Got them both in under a minute, which is a good recovery after actually getting Monday's puzzle wrong!
|Mar-30-07|| ||TrueBlue: 31 Rd7+ also works ...|
|Mar-30-07|| ||Jack Kerouac: That knight did seem to 'leap'into the solution.|
|Mar-30-07|| ||TrueBlue: the 64K question. Am I getting better or are puzzles getting easier?|
|Mar-30-07|| ||Fezzik: It seems that this week's theme is "Bolts from the Blue". These sorts of moves are the type of moves that are easy to calculate, *if you see them*. |
The problem is that very often chess players don't even look for these shots. These positions are instructive but lacking as puzzles because puzzlers are looking for that weird first forcing move.
Strong chess players are finding these types of moves with tremendous regularity compared to, say, twenty years ago. Strong players have learned to see these for two main reasons: the rigor of computer analysis coupled with today's competitive chess scene.
|Mar-30-07|| ||dakgootje: The reason why most people find this an easy puzzle is most probably because of the lack of candidate moves. In that position white can't win the war with only his mere rook and queen, no, more is needed. But what good can the knight do? and the rook at c1, okay it's at a nice file, but face it, there is a blood knight places in front. Conclusion the knight has to be removed.|
The only somewhat forcing way is Nd5 which turns out to be the right move. Exd5 is to be expected, so what's next? 30. Rxc8, 30. Rxd6 or 30. Rf8?
First doesn't really give any great compensation, latter is not too hard to find out what's next and analysed by euripides and is... hmmm... not really clear. Probably relatively equal for black's rooks can come in annoying however white's queen isn't powerless either and has a h-pawn to march.
Leaving us with Rxd5 and if you get unto there the forcing continuations aren't too hard to find.
|Mar-30-07|| ||Peligroso Patzer: Also winning (after 30. ... Bd7) would have been: 31.Rxd7+, for example: 31...Kxd7 32.Rc7+ Kxc7 33.Qxe7+ Kc8 (33...Kb8 34.Qe5+ ) 34.Qe6+ Kb7 35.Qxd5+ .|
Another winning 31st move would have been: 31.Qxd5, for example: 31. ... Rb7 32.Rxa6 Rb8 33.Rb6 Rc8 34.Rxc8+ Kxc8 35.Qa8+ Kc7 36.Qa7+ Kd8 37.Rb8+ Bc8 38.Rxc8+ Kxc8 39.Qxe7 .
|Mar-30-07|| ||Peligroso Patzer: By the way, to give proper attribution for the variations in my previous post, the analysis of the 31. Rxd7+ line is my own. The 31. Qxd5 line turned up when I used Fritz to verify my analyisis of 31. Rxd7+.|
|Mar-30-07|| ||realbrob: Some minutes of hard thinking but then I got it! A remarkable amount of pins.. It wasn't a very good idea for Black to put his king on the same diagonal of the White queen, even though his position wasn't easy at all.. Could have been an improvement 28..Rf8?|
|Mar-30-07|| ||zb2cr: I'm with <al wazir> & <mkrk17>. Oh well.|
|Mar-30-07|| ||scholes: is it wrong ♘d5 exd5 ♖xd6 ♗d7 ♖xd7 ♔xd7 ♖c7+ ♔xc7 ♕xe7|
|Mar-30-07|| ||triangulation: This has been a good week for me.got the whole thing after about five minutes. The first move seemed pretty obvious. only thing left was to check if black had any saving moves.|
|Mar-30-07|| ||Bingat29: The set back of 31. Rd7 instead of 31. Rc8, is that, both rooks will be lost. It will thus be 2 rooks for a queen. The alternative 31. Rc7 QxQ, only regains the minor piece with advantage but the game is far from over. White's immediate problem is the threatened perpetual check once black occupies Rh7. Note that the h pawn will be interposed on the g file once the queens are exchanged. There is nothing better than the text move 31. Rc8+ because white retains one of the rooks. Nice puzzle and a brilliant game.|
31. Qd5 is best answered by Qn2 threatening mate. No matter white does, blacks gain a tempo and the momentum. If white checks the king moves to e7 threatening to capture the rook.
