Dec-07-10  scormus: <Once> A nice perspective on Nd5 from a player who, by his own admission, eschews these sharp hairy-chested openings.

The first time I saw this move played, at that time it still wasnt well known at the sort of level we played, it was by a team mate against a rather strong player from another club. It probably wasnt excatly the same position as here - I think it went (B) ... b5 (W) Nd5 (B) exd5 (W) Nf5. Then B thought for a long time and said, "it looks like this is one lesson I'm going to learn the hard way."

I cant remember the moves but W won spectacularly and I decided more than anything else in chess ... I wanted to play a game against the Najdorf and win with that move.

Dec-07-10  gmalino: I needed much too long for this one, because the defence seems to be good. But after

35. Qxf8+ Bxf8 (only move)
36. Re8#

it's over.
A lot of pinned pieces around, only looking for the very forced continuation leads to victory. Good Thuesday!

Dec-07-10  Ratt Boy: The picture wasn't finished loading; it was showing ranks 5-8 when I said to self, "What about Qxf8?" For me, this was a mite easier than yesterday's.
Dec-07-10  zb2cr: This is quite easy. The pin on the Black Bishop at d7 makes possible 35. Qxf8+, Bxf8; 36.Re8#.

Picturesque.

Dec-07-10  Patriot: At first I just sort of glanced at the position and didn't sense the mate so I looked at material differences first (going by procedure). White has 2 pawns for a piece. Then before I could consider black's threats, I thought "What if 35.Qxf8+? 35...Bxf8 and 36.Re8 mate!"
Dec-07-10  awfulhangover: LOL! Black has a fence of pieces around his majesty, but the white lady teared down the wall with a suicidal attack.
Dec-07-10  JuliusCaesar: This one was easy. 12. Nd5 is a typical sac in these positions, very much la Tal. In fact, White played the entire game in the spirit of the great Latvian.
Dec-07-10  desiobu: What's the idea behind 32...d5? Just trying to trade queens or what?
Dec-07-10  Patriot: <<desiobu>: What's the idea behind 32...d5? Just trying to trade queens or what?>

I'm thinking that could be his only practical chance. White threatens to play h7, so on 32...d5 33.h7? Qxg6 34.Bxg6 it's much more difficult for white to win. Black is in a bind for sure.

  kevin86: In some ways,this can pass as a Monday puzzle-I think it would be EVEN Easier as a Monday puzzle. People would look first to the queen sac that leads to mate.

Yet,even another mate on the Reti-Tartokower theme.

Dec-07-10  DarthStapler: Got it easily
Dec-07-10  Brandon plays: Another queen sack.;) That took me 10 seconds. It seems like at some point we almost expect these types of moves.

  gawain: Nice finish. Sac the Q for the f8 rook, then Re8 mate. What a pin!
Dec-07-10  MiCrooks: I like others found this easily and was curious how this interesting position came about. Turns out that Black blundered with his last move, easy to do with all the tactics flying around. Qf6?? lead to immediate loss, but Kc8! and the game is still quite interesting.

Black has a number of threats of his own AND is up a piece at the moment. White's advanced h-pawn might become a threat but in this position I think not. The key issue here is that Black was under the illusion that he was chained to his Bishop on e7. But after Kc8! Rxe7?? and it is White getting mated with Qxc2+ Ka1 Qc1++.

It is hard to come up with a good move for White here. He is probably not losing but he must be just as careful as Black. Not only is c2 an issue but so is the back rank. Plus if he is not careful he could end up being unable to defend all of his strung out pieces. Rd1 lends itself to mind after which Qf6 and Black is trading into an endgame he has good chances in.

Dec-07-10  Nullifidian: Saw this one immediately:

35. ♕xf8+ ♗xf8▢ 36. ♖e8#

  Jimfromprovidence: Interesting game. 34 Be6, below, not allowing 34...Kc8 and seeing 35 Red2 would have made a nice position to study.

  patzer2: It appears both sides could improve on their 34th move.

White's 34. Qg7 allows 34...Kc8! to = with counter chances (e.g. 34. Qg7 Kc8 35. Rd1 Qf6! with a complicated and unclear position with roughly even chances, which appear to slightly favor Black).

Instead, 34. Be6! b3 35. Rde2! keeps a clear winning edge.

Obviously 34...Qf6??, allowing 35. Qxf8?? Bxf8 36. Re8# was a blunder.

Instead 34...Kc8! to = gives Black excellent counter chances in a complicated position.

Fritz 10 at 21 depth gives 34...Kc8! 35. Rd1 Qf6 36. Bd5 Bd8 37. Qg2! Kb8! (not 37...Qxh6? 38. Be6! to ) 38. Qf2 a3 with a slight advantage for Black, but the position is so difficult it's not clear this is the best line.

Dec-07-10  licuan: repeated theme,i solve this one to easily. Just for today
Dec-07-10  James Bowman: Not bad about 30 seconds I suppose.
Dec-08-10  TheaN: Tuesday 7 December post-publication

<35.?>

Material: Black up, 2♗ vs ♗+2♙

Candidates: Qxf8

-ML-
Pinned pieces are bad defenders. So bad, that this sequence is completely forced even with all the Black pieces near his king.

<35.Qxf8! Bxf8 36.Re8 1-0> and the pin on the bishop on d7 is present the entire combination, whilst the fictive pin on the bishop on e7 became Black's downfall. I got the faint conclusion this puzzle is more about the game rather than the puzzle though, too bad I can't see it here.

May-07-12  lemaire90: Wow ! Fantastic finale.
Sep-10-12  sav1ola: nice jobava good player
