Sep-17-07   pawnofdoom: Great for a Monday puzzle. I could actaully solve it.
Sep-17-07   Ercan: I can not open the game. It's there a (java?) problem.

  willyfly: <Ercan> I had that problem with ChessTutor a few days ago so I switched my selection to MyChess(default) and later switched to ChessTutor again and then it worked fine
Sep-17-07   Ercan: willyfly, Thanks your advice but the problem is solved by itself...

  Peligroso Patzer: <Breunor: Why [6] Nde2? I looked it up in the database, there are some 10 games or so with this move, but why play it? >

I assume the idea is to prevent 6. ... d5 (by unblocking the d-file), but 6. Bc4 seems like a more logical way to deal with this "threat". I frankly doubt that Black should play ... d5 before castling, but the following line (treating the position BEFORE 6.Nde2 as if it were Black to play) seems to favor Black slightly: 6. ... d5 7.exd5 Nxd5 8.Bb5+ c6 9.Nxc6 bxc6 10.Qxd5 Qxd5 11.Nxd5 cxb5 12.Nc7+ Kd7 13.Nxa8 since the Knight on a8 will be captured.

  Peligroso Patzer: Congratulations, <stanleys>, on finding 2. ... Qxg2+ in time pressure (after 1. ... Bxc3! 2. Qxc3?? from the position in the diagram you posted). Your 1. ... Bxc3 appears to have been best, but your opponent obviously should have played 2. Qe2 or 2. Qc2 and tried to hold the pawn-down position. Having overlooked the fact that his c3-pawn was not actually defended, in time pressure he played the natural but fatal (to his own position) response to your 1. ... Bxc3!
Sep-17-07   zb2cr: Okay, Black has two threats of mate on the move. For White to win, his move must give check--and there it is, 40. Qxg7+, Bxg7 (forced); 41. Rxe8+, Bf8; 42. Rxf8#.

Very simple to see, took me under 5 seconds.

Sep-17-07   Alphastar: <Breunor> Like <Peligroso Patzer> says, it is to prevent black from freeing his position with 6. ..d5. If white would move 6. g3 directly, black could get in that 6. ..d5 move.

6. Bc4 allows black easy equality though: ..O-O 7. O-O Nxe4 8. Nxe4 d5 =

  kevin86: Great Monday puzzle! White must act quickly as he is threatened with two mates on the move. An immediate Rxe8 loses as it sucuumbs to Qxg2#. The rook capture must be with check-and it is after the queen sac opens the gate. The bishop can then reclose the gate,but the rook bursts through on the third move to mate.

Just think:a queen is sacrificed to move one piece just one square,but the move is so strong that the game is decided in just three moves!

  playground player: So my computer crashed and burned, out for the whole weekend, missed the end of "The Battle of the Brains" (I presume my team lost), missed the Fri-Sat-Sun puzzles... I guess if you gotta go through all that, it's best to come back on a Monday. Sometimes the Monday puzzle is just what a body needs. (Yes, of course I solved it!)

  Crowaholic: <stanleys>: Thanks for the example. The most interesting part is that the queen sac deflects _and_ pins the white rook, allowing a swift mate on the now wide open back rank.

  fm avari viraf: In Chess, one must have a hawk-eyed & never be scared of sacrificing pieces to attain the combination. Here, Black's Back Rank is vulnerable & so the Queen sac on g7 was possible.
Sep-17-07   silviochess: As a puzzle a very easy one. It is interesting as an exemple of a very promising, even overwhelming
position leading to disaster due to a hidden and tiny detail, a tempo really.

  patzer2: For today's solution, White has mate in three via the decoy sham sacrifice of the Queen with 40. Qxg7+! See <TheaN>'s post for the followup finish.

  jheiner: <what about the continuation 35....Nxh4 36.Bxh4 Bxg2+ 37. Kg1 Bh1 38. Re2 Nxf4! Black's attack carries itself/...??>

Same continuation: 38... Nxf4?? 39. Qxg7+ Bxg7 40. Rxe8+ Bf8 41. Rxf8#

  jheiner: However, the simple Qc6 covers the backrank mate for Black, solidifies his position and now the f6 Knight can come out and play:

36. ... Nxh4 37. Bxh4 Bxg2+ 38. Kg1 Bh1 39. Re2 Qc6!

Sep-17-07   dmeng: 40. Qxg7+ Bxg7 41. Rxe8 Bf8 42. Rxf8#

Now to see how long I can last this week. My rating isn't very high at all...(like 1200 or so)

39. Qc6? misses a forced mate (Hiarcs-aided): 39. ... Nd4 40. Re4 Qxe4 41. c4 Ne2+ 42. Kf1 Qf3+ 43. Ke1 Nc3+ 44. Kd2 Qd1#

Sep-18-07   stanleys: <Peligroso Patzer:> Thanks!

<Having overlooked the fact that his c3-pawn was not actually defended,>

His problem was that he was only expecting 2...Rxb1
