Feb-24-06  LIFE Master AJ: Hmmm. I got the first move. (Got to come back and look at this one after I do some computer analysis.)

Did anyone find an alternate solution?

Feb-24-06  WarmasterKron: I saw this one up to 38. Nh7, which I considered for a while and dismissed because I mistakenly thought black would be OK after ...Rxc8.
Feb-24-06  EmperorAtahualpa: Because I missed the (brilliant) move 38.Nh7 I didn't see the point of 36.Rc8+, so I was just guessing that the right move is 36.Rcc7. :(

This has to be my worst week in a long time...I only found Monday's puzzle!

Feb-24-06  psmith: Well, I got the whole thing. Yippee!
Feb-24-06  Fan of Leko: Took a while (over 5 mins.) but i did find it. In a game, where i wouldn't know there was a win, who knows?
Feb-24-06  Fan of Leko: Even up the exchange white still has to be careful. Many players get careless after winning material. For instance 41 Rf8-f7 Rg6 and black wins a pawn back. 41 Kh2 takes care of that threat.
Feb-24-06  dakgootje: First i thought that this puzzle was way to easy for friday, but when i saw that lots of people missed it, i realised that i was probably lucky to look at the right move as first candidate move. Only i expected black to resign after it got the first 7 half moves (so untill Rxf8), but all in all it took maybe a minute or less to calculate everything.
Feb-24-06  starkidaway: at first thought 36.Rc8+ Rf8 37.Rcc7 (now the knight cant be taken because of mate) ...Rg6 (forced) 38.Ne6 Rxf2 39.Rc8+ kh7 40.Nf8+ RxN

and there I stopped because I thought it was winning. But anyhow, I believe the game continuation was better because it has one more pawn.

now did I solved the puzzle?

  Peligroso Patzer: <MrsMurdstone> asks, "Can't black keep playing, with his two pieces, and hope for a miracle?" After 44. ... Rb2, Black is totally lost because, as he probably noticed too late, White can play 45. Ra6. This pins the Knight on e6, which Black has no way to defend. Still, Mestrovic might have waited until Razuvaev had actually played 45. Ra6 before he resigned.
Feb-24-06  alphee: <al wazir> What you indicate does not look like a Mate.

37. ♖cc7 hxg5 38.♖xg7+ ♔h8 39. ♖h7+ ♔g8 40. ♖ag7#.

What we may get is a draw by repetition with 40. ... ♔f8 41.♖a7 (or b7/c7) ♔g8 42. ♖g7 ♔f8 43. ♖a7 and so on...

Did I miss something?

  YouRang: <chessgames.com> must have felt bad about giving us such a tough Thursday puzzle -- they made up for it by making the Friday puzzle relatively straightforward.

Here, the first think you look at is the checking/forcing rook moves, which results with the white rooks doubled on the 8th rank and the black rook forced to f8. Black must now double his rooks (Rd8 or Rf6), but either way he does it, his rooks are hit with a knight fork. :)

Feb-24-06  dakgootje: <alphee: Did I miss something?> Yes you missed that blacks rook is already on f8 so you get

  kevin86: I picked this one up rather easily-unusual for a Friday! How elegant was the rook fork by the knight at h7!! I saw the eighth rank attack because of black's king being hemmed in by the knight.
Feb-24-06  alphee: <dakgootje> thanks, I missed that, next time I take a board to check. :o(
Feb-24-06  Bigfatpatzer: I thought 37. Rc8 Rf8, followed by the finesse 38. Rcc7, which means that the knight is immune. So, if for instance, 38...Rf4, then 39. Rxg7 etc.
Feb-24-06  Mating Net: I didn't get 38.Nh7! To me, it is a super sharp move. It combines two tactical themes. Thedeflection of the Black King, and if the King doesn't capture the beast, an intermezzo via 39.Nxf6+. Pretty cool.
Feb-24-06  JustAFish: I followed Starkidaway's line as well... Rg6 was hard to see, though.
Feb-24-06  pwrstick: Hello again all,

Would someone kindly suggest the final end game sequence? I'm having difficulty seeing why black resigned (other than being down a rook).

  tpstar: <pwrstick> After 44. g4 Black's endgame is very hard to hold, like 44 ... Nd8 45. Rd7 Nb7 (45 ... Nc6?? 46. Rd6+; 45 ... Ne6?? 46. Rd6) 46. Rff7 and the Pg7 falls. But 44 ... Rb2?? was fatal due to 45. Ra6 winning the Ne6 next move.
Feb-24-06  pwrstick: I suppose Ra6 to threaten the knight is rather devastating as it pins it to the king. And there's no way to defend its eventual capture...
Feb-24-06  VinnyRoo2002: To answer Life Master AJ's question, I found an alternative solution with 38. Ne6 Rxc8 39. Rc8 Kh7 40. Nf8+ Kg8 41. Nd7+ winning the exchange also. Not sure if this end position is superior or inferior to the one in the game though.
Feb-24-06  VinnyRoo2002: Sorry, I overlooked 39... Kf7 when white doesn't win any material. I did see the Nh7 line though.
Feb-24-06  c o r e: I soved today's puzzle on intuition alone- then spent five times as long trying to disprove it. I kept thinking to myself 'I must have missed something in this line...'

I find that I all too often underestimate my opponent's counterplay in these situations, but today's puzzle position would have had me nearly throwing the win away if controls were at 40.

Feb-26-06  LIFE Master AJ: My alternate solution involved 37.Rcc7, Rg6; 38.Ne6, which I originally thought won ... and better than the game. (But apprently not.)
