< Earlier Kibitzing · PAGE 3 OF 3 · Later Kibitzing>
Dec-20-14		Edeltalent: I thought I had it completely figured out, while I in fact completely missed 28...Ke7 (presumably because this square was still covered by the Queen on the previous move. Although 29.Re1 then looks obvious and crushing, this is sloppy calculation.

Dec-20-14		Moszkowski012273: Nice analysis <TheaN>......

Dec-20-14		kevin86: The black bishop prevents the easy mate in three by queen sac, but a king hunt will give white the victory. The sacrifices are smaller but no less rewarding.

Dec-20-14		agb2002: White has the bishop pair for a bishop, a knight and a pawn. The first idea that comes to mind is 24.Bxg6 fxg6 (24... hxg6 25.Qh8#; 24... f6 25.Bf7+ Kh8 26.Rg8#) 25.Rxg6+ hxg6 (25... Kf7 26.Qxh7+ Bg7 27.Qxg7#; 25... Bg7 26.Rxg7+ Qxg7 27.Bxg7 + - [Q+P vs R+N]) 26.Qh8+ Kf7 27.Qh7+ Ke6 28.Qxg6+ Ke7 29.Re1 (threatens 30.Bd6#) but I'm not sure if this wins for White. I don't have time for more today.

Dec-20-14		TheaN: Just for the record, for people that don't want to read through all my analysis, <28....Ke7=> is a draw by repetition. All of white's tries go astray, of which <29.Re1 Qxa4!> is the most prominent. I still see people talk about a win after 29.Re1, but it is not.

Dec-20-14		Yopo: What's wrong with 24 Qxh7+ Kxh7 25 Rh5+ Kg8 26 Rh8checkmate?

Dec-20-14		Gregor Samsa Mendel: <Yopo>--24 Qxh7+ Kh7 25 Rh5+ Bh6.

Dec-20-14		Richard Taylor: Good combo / attack which I failed to find. Should have been fairly obvious but thought it might start with f4 as the Q sac didn't work. I rejected the Bxg6 without reconsidering it. I think OTB it is easier as you are attacking and have a plan leading up to an assault on the King. It helps to have 2400 odd rating points of course...

Dec-20-14		Richard Taylor: It just shows you can win a brilliant game from what is reputed to be a boring opening. It proves that you can win no matter what you play in the opening. As black or white....

Dec-20-14		Richard Taylor: Well my "engine" finds a draw or equality for black with the right defence. Hard perhaps to find over the board though I suppose. After 28. ... Ke7 Black seems to hold the position. Here's the proof that white won by a swindle: After 24. Bxg6 (the best move) fxg6 25. Rxg6+ hxg6 26. Qh8+ Kf7 27. Qh7+ Ke6 28. Qxg6+ Ke7 29. Re1 Qxa4 30. Qh7+ Ke6 31. Bc7+ Ne3 32. Rxe3+ Kd5 33. Qh5+ Kc6 34. Rxe8 Qa1+ 35. Kh2 Rxe8 36. Qxe8+ Kxc7 37. Qxf8 Qxd4 The position is clearly equal. 28. ... Nf6 was an error leading to black's loss of the game.

Dec-20-14		Jimfromprovidence: <TheaN> <All of white's tries go astray, of which <29.Re1 Qxa4!> is the most prominent. I still see people talk about a win after 29.Re1, but it is not.> True, but there is a more game left after 30 Qh7+ Ke6 Bf4+!?. click for larger view Black's knight saves him with 31...Ne3, creating a safe square at d5. click for larger view For those interested, the question is how white salvages the position from this point onward.

Dec-20-14		Richard Taylor: < Jimfromprovidence: <TheaN> <All of white's tries go astray, of which <29.Re1 Qxa4!> is the most prominent. I still see people talk about a win after 29.Re1, but it is not.>> It is true after the fact, but in a real game most players would probably fold, or might well do so under pressure from white's attack. This is in a sense what we might call a 'true' sacrifice by black. A mix of calculation and intuition and a desire to win. It worked. Such is chess.

Dec-20-14		Cheapo by the Dozen: Well, like many folks I saw the first five moves but not the win after those. I'm glad to see the analysis indicating there wasn't actually a win to miss.

Dec-21-14		al wazir: <Abdel Irada: <31...Qc6. Now what?> I suppose 32. Bg3+, Kd7 33. Qf5+, Re6 34. d5 should suffice.<<>>> Yes, that works. Thanks.

Dec-21-14		CHESSTTCAMPS: Black's king-side is weakened on the dark squares and white has mobilized substantially in that region to exploit that weakness, expending a pawn in the process. Looking at forcing breakthroughs, 24.Qxh7+?? Kxh7 25.Rh5+ Kg8?? 26.Rh8# works beautifully, but 25... Bh6 leaves white with no good continuation. Next to examine is the pawn-shelter clearing 24.Bxg6!!. It isn't hard to see that black's bunched major pieces do not defend the king from checks from the right. It is easy to foresee at least a draw, but working out a win is much more effort. Here goes! 24.Bxg6!! fxg6 (hxg6? 25.Qh8#; or h6 25.Bf7+ Kh7 26.Qg6#) 25.Rxg6+! hxg6 26.Qh8+ (Qg6+?? Bg7) Kf7 27.Qh7+ and now: A) 27... Ke6 28.Qxg6+ Ke7 29.Re1! (threatening Bd6#) Qe6 30.Qh7+ Qf7 31.Bc7+ Kd7 32.Qxf7+ wins A.1) 28... Nf6 29.Qxf6+ Kd5 30.Qf3+ Ke6 31.Re1! (Threatening 32.Bc7#. The draw 31.Qf6+ is available if white is not confident of the advantage) and now: A.1.1 31... Qe7\|f7\|g7\|h7 32.Bb8+ Kd7 33.Qxg7# A.1.2 31... Qd5 32.Bb8+ Kd7 33.Qxd5+ Kc8 34.Rxe8 wins A.1.3 31... Qd6 32.Bxd6+ wins A.1.4 31... Qc6 33.d5+! Rxd5 (Qxd5 34.Bg3+ Kd7 35.Qxd5+ wins) 34.Bg3+ Kd7 35.Qf7+ wins A.1.5 31... Qc8 32.Bg3+ Kd7 33.Qf5+ Kc6 34.Qb5# B) 28... Bg7 29.Qxg7+ Ke6 30.Qg6+ Ke7 31.Re1 Kf8 32.Bd6+! Ne7 (Qxd6 33.Rxd8+ Rxd8 34.Qxd6+) 33.Qf6+ Kg8 34.Bxe7 Qxd4 (Re8 35.Qg6+ Kh8 36.Bf6+ wins) 35.Qg6+ Qg7 36.Qxg7+ Kxg7 37.Bxd8 wins B.1 31... Rmoves 32.Bd6# OK, I know there's more, but I think that covers much of the solution. Time to post and review.

Dec-24-14		Yopo: <Gregor Samsa Mendel> Thank you. Now, I can see.

Dec-10-19		FSR: Blame it on Rio.

Mar-14-25		Granny O Doul: Somehow my eyes were drawn right to 29. Qxf6+. It has that certain "something" that's hard to put into words.

Mar-14-25		chrisowen: Catch my fire x

Mar-14-25		King.Arthur.Brazil: The king line seems simple: 29. Qxf6+ Kd5 30. Qf3+ Ke6 31. Re1 Qc6 32. Bg3+ Kd7 33. Qf7+ Be7 34. d5 Qc5 35. d6 Kc8 36. dxe7... Other moves different from Qc6 seems worst for B.

Mar-15-25		Breunor: White has a win up until the last move: Stockfish gives: 1) +8.78 (27 ply) 32.Re2 Qc6 33. Bg3+ Kd7 34. Qf5+ Re6 35. d5 Re8 36. dxc6+ bxc6 37. Kh2 c3 38. h5 Bd6 39. Bxd6 Kxd6 40. Rxe6+ Rxe6 41. Qd3+ Kc5 42. Qxc3+ Kd5 43. f4 c5 44. Kg3 c4 45. Kg4 Kc5 46. Kg5 Re8 47. h6 Rg8+ 48. Kf5 Rf8+ 49. Kg4 Rg8+ 50. Kf3 a6 51. h7 Ra8 52. Kg4 Ra7 2) +8.62 (26 ply) 32.Qf6+ Kd5 33. Qf3+ Ke6 34. Re2 Qc6 35. Bg3+ Kd7 36. Qf5+ Qe6 37. Rxe6 Rxe6 38. d5 Re8 39. dxe6+ Rxe6 40. Qb5+ Kd8 41. Qxb4 a6 42. Qxc4 Ke7 43. Kh2 b5 44. Qc5+ Kf7 45. Qf5+ Ke7 46. a5 Rc6 47. Qh5 but after d5+ it gives: 32...Qxd5 33.Bc3+ Kd6 34.Rd1 Qxd1+ 35.Qxd1+ Kc7 36.Qg4 Bxc3 37.Qxc4+ = +0.31 (11 ply)1-0 So Black had gotten back essentially to equality when he resigned (or ran out of time?)

Mar-15-25		mel gibson: That was all forced. Stockfish 17 says: 29. Qxf6+ (29. Qxf6+ (1.Qxf6+ Kd5 2.Qf3+ Ke6 3.Re1 Bb4 4.Re2 Qc6 5.Bg3+ Kd7 6.Qf5+ Re6 7.d5 Rde8 8.dxc6+ bxc6 9.Kh2 a5 10.f3 R8e7 11.h5 Re8 12.Re4 Bc3) +30.40 38 754) score for White +30.40 depth 38.

Mar-15-25		Walter Glattke: 29.Bxf6 Rc8 30.Bd5+ also wins

Mar-15-25		mel gibson: <Walter Glattke: 29.Bxf6 Rc8 30.Bd5+ also wins> No it doesn't - that's a draw according to SF17.

Mar-16-25		Hercdon: White did find the winning move but then slipped into Draw City on move 32 unnecessarily. Not sure how they won the drawn ending - time trouble?
