Jan-09-06  ColoradoHamster: Yeah, Mondays are good for the ego. Even I saw this one pretty fast :-)
Jan-09-06  erimiro1: Back to Monday...ahhh..Immediately after 34.Qh8+! Black could stop the clock. 33.-Kh7?? was a blunder. Correct was 33.-Qf8! that leaves white with a clear advantage and black with minor hopes.
Jan-09-06  Endgame: wow, that was pretty simple. Alot easier than yesterdays
Jan-09-06  blingice: Easy.

<Endgame> Puzzles are hardest on Sundays, easiest on Mondays.

Jan-09-06  thathwamasi: Pretty Petrosianesque....IN my opinion Qh8+ was the greatest move made in championship history..I mean, the petrosian vs spassky 1966 round ten.

  dzechiel: I spent quite a bit of time trying to decide between 34 Qh8+ and 34 Nxf7 (because I noticed that the discovered check with the black knight isn't a real threat). When I started looking for flight squares for the black queen, I then noticed 34...Qd2+ and that made me choose 34 Qh8+ as the only viable line of play.

  patzer2: For today's puzzle solution, White initiates a Knight Fork with 34. Qh8+! which serves as both an offensive and defensive move. It is defensive in the sense that other moves, such as 34. Nxf7?? Qd2+ , turn the tables and allow Black to win. It is offensive because it simplifies to a won ending.

IMO Black's initial error in losing this game is 24...Rc8?!, offering to simplify to an ending favorable to White. Better was 24...h6, maintaining the tension with near equality in the position.

  yoozum: About as easy as Monday puzzles get.
Jan-09-06  prinsallan: Yep, setting up a fork that becomes the clencher.
Saw it all the way from now til doomsday ^^

  Dim Weasel: Got the correct solution right away, but I must admit that I still spent some time looking for a mate or queen win (instead of won endgame) because it is Monday.

  melianis: 37. b3 gets white a 3 pawn advantage, which in this case is enough for a win ;-).

  cu8sfan: For a Monday puzzle I found this exceptionally hard. I found the solution all right but then I thought "Heck, this can't be right. A Monday puzzle whose solution leads to a Knight endgame where you're two pawns up, that's not enough."

  EmperorAtahualpa: 34.Qh8+! I found the move almost instantly, but waited a little longer to see if there was an even better move that would lead to a bigger advantage than two or three pawns.

This puzzle is just right for a Monday!

Jan-09-06  Parteepants: I found the queen move almost immediately, but spent a little time looking for something that might be more conclusive. As we all know, sometimes the most obvious move isn't the best move...that is, unless it is a Monday at Chessgames.com. And since I couldn't find anything better, I settled on Qh8+.
Jan-09-06  Father Karras: Reminds me of a game between Alekhine and Euwe where both players missed a similar Queen sac for several moves.
Jan-09-06  eaglewing: While the combination should give a winning position considering the two pawn advantage, I think 36....Nd3 was a bad choice.

I would think with 36. ... a4 37. Nc4 (or b5?) Nd3 38. Kg2 Kf7 39. Kf1 Kf6 40. Ke2 Nc5 there could be at least some fighting chances. Or could you outline an easy and secure winning continuation (or variation) following the a4-line?

Jan-09-06  rishi: Mondays...

Although i wouldn't consider this a Q sacriface...if you know u r getting a Q back the next move, is it still called a sacriface? may be till u play the next move!

Jan-09-06  Hudson Hawk: I'm with <Dim Weasel> I saw the pawn winning move fairly quickly but I kept thinking their must be some mate forcing move.

  patzer2: As an early equalizing try, Fritz 8's suggestion 15...b5! 16.Nb1 a5 = to looks interesting, since it appears to take away some of the strong Queenside initiative White enjoyed in this game.
Jan-09-06  Antipholous: <rishi> It's still a sacrifice. A sacrifice is giving up material to gain a position where you can gain even better material and position.

If we're not giving up material to gain something else in return, we call that a blunder.

find (36...?) Black's strongest winning move.

3. After 34. Nxf7?? Qd2+ 35. Kg3 Ne2+ 36. Kf2 (diagram below),

find (36...?) Black's winning move(s).

Jan-09-06  Caro.K.4.me: <patzer2> That's OK. I can't do mate in two's very good yet. I'm working on openings, I already memorized two openings in CAro-Kann one's called Fantasy, and another is called the Great Panovbot, or something. Besides I'm finishing a book by Fischer where he's teaching me chess and after I finish doing the puzzles in this one I'm gonna read The Art of Attack, and then I'll be ready for mate-in-two's. But thanks anyways!!! :)

  beenthere240: The challenge inherent in the position for white is to get the queens off the board, after which the pawn majority on the queen side is an easy win. The win of the f pawn is inconsequential.

  LIFE Master AJ: Qh8+ followed by grabbing the f7-pawn. This Knight fork regains the Queen and leaves White several Pawns ahead.
