| Feb-04-22 | | Brenin: White is down by N for 2P, and has Q and N en prise, sp he is probably going to be happy with a draw. Let's try 42 Rxe3 Qxe3 (43 ... Rxh5 44 Rxe5 leaves White 2P up) 43 Qg6+ Kf8 44 Qf6+ Nf7 (44 ... Rf7 45 Qxh8+, or 44 ... Kg8 45 Qd8+ and 46 Qxc7+, or 44 ... Kd8 45 Rd1 Nf7 46 Bg6) 45 Rf1, with an unclear position, offering White good chances of at least a draw. Unsatisfactory, but that's the best I can do. |

| Feb-04-22 | | Honey Blend: White missed 45. ♕d8+ ♔g7 46. ♕xc7+ ♔h6 47. ♘e2! and black cannot play 47. ... ♕xe2 because of 48. ♕f4!
click for larger viewAmong many threats are ♕f6+ and ♕h4+, Black loses his bishop if it moves, the Knight is pinned and the Rook can't do much. |
|
| Feb-04-22 | | Honey Blend: 45. ♕d8+ ♔g7 46. ♕xc7+ ♘f7 47. ♖f1 ♖f8 48. ♘e4 doesn't help Black much either with ♘d6 and ♕e7 coming. |
|
| Feb-04-22 | | Brenin: After 42 Rxe3 Qxe3 44 Qg6+ Kf8 45 Qf6+ Nf7 46 Rf1 each side's best chance seems to be taking a draw with 46 ... Kg8 47 Qg6+ Kf8 48 Qf6, e.g. bad alternatives for Black include 46 ... Qh6, (threatening Qxh2 mate) 47 Qd8+ and 48 Qxc7, defending h2. A draw seems a fair result, though Black missed a probable win with 41 ... Qf6 instead of 41 ... Rh8, since 42 Rxe3 allows a back-rank mate. |
|
| Feb-04-22 | | BxChess: It is hard to convey my joy at solving this Friday puzzle. For the first time ever I was zero from four this week. I seriously feared some sudden catastrophic mental failure. Instead I can content myself with a more gradual decline. |
|
| Feb-04-22 | | Refused: 1.Rxe3 is forced because of those threats along the h-file
1...Qxe3 (what else) 2.Qg6+ Kf8 3.Qf6+ Kg8 (otherwise Qxh8+) 4.Qd8 Kg7 +- 5.Qxc7+ yeah, that everything drops with a check comes in very handy. |
|
| Feb-04-22 | | FM David H. Levin: <Honey Blend: White missed 45. Qd8+ Kg7 46. Qxc7+ Kh6 47. Ne2! and black cannot play 47. ... Qxe2 because of 48. Qf4!> That's pretty. Perhaps a stiffer defense is 47...Rf8! (renewing the threat of ...Qxe2 and threatening ...Qxc1+), 
click for larger viewbut after 48. h4 Ne4 (48...Rh8 would be defused by 49. Qf4) 49. Bxe4 Qxe4 50. Ng1 Rf4 (50...Qxh4+ 51. Nh3) 51. Rc3, White seems to be consolidating. |

| Feb-04-22 | | mel gibson: I got this one so wrong.
I chose 42. Qg6+ thinking that I could sacrifice a Rook on f1 and go for a win.
However that leads to a bad loss.

 | | scormus: For all the threats W had on the BK, I was surprised to see it come out 1/2-1/2. Which it should do but only if 44 .... Nf7! followed by the interesting tactical exchange <mel gibson> posted. After 44 .... Kg8??, 45 Qc8+ Kg7 46 Qxc7+ Kh6. B has lost a tempo and blocked the h-file. Clear advantage to W but more work to do to win. 45 Qc8+ is so obvious (IMO), I am surprised W didn't play it. Even got a second chance 2 moves later |
|
| Feb-04-22 | | Brenin: <scormus>: I think you mean 45 Qd7+, not Qc7+. I'm sure that Black saw this move (even a beginner would), but rejected it because he saw the obvious continuation 45 ... Kg7 46 Qxc7+ Kh6 47 Ne2 Qxe2, losing a piece, and overlooked the far from obvious refutation 48 Qf4, when the threats of 49 h4 and of 49 Qh4+ and 50 Qxg5 are hard for Black to deal with. |
|
| Feb-04-22 | | parch: Choice of 42.Qg6+ and 42.R:e3
42.Qg6+ Kf8 43.Rf1+ N:f1 44.R:f1+ Rf7 45.R:f7 N:f7 42.R:e3 Q:e3 43.Qg6+ Kf8 44.Qf6+
( stronger than 44.Rf1+ Rf7 )
44...Nf7 45.Rf1 Kg8 46.Bg6 Rh7 looks better for black
(46...R:h2+ 47.K:h2 Qe5+ ) |
|
| Feb-04-22 | | saturn2: First you try 42.Qg6 but it yields nothing because the the Qe5 covers f6 and mate on h2 is the threat.
So try 42.Rxe3 42...Rxh5 loses a piece so
42...Qxe3 43.Qg6+ Kf8 44. Qf6+ Kg8 45. Qd8+ Kg7 46.Qxc7 Kh6 herre I gave up thinking it remains a tie but as shown by <Honey Blend> 47.Ne2 Qxe2
48.Qf4 wins. White can pin the queen later by Bd1 |

 | | Dionysius1: And of course switching order with 42.♕g6+ ♔f8 43.♖xe3 doesn't work because of the threat to h2 |
|
| Feb-04-22 | | King.Arthur.Brazil: I hope you will not crucify me, but I wonder this one is a simply beautiful and easy one. Follow me. White ♕ has no immediate refuge, except 42.♕g6+, but this atack only works if 1) the ♖ enters on f1, while 2) the Black ♕ is desviated from the defense and the immediate threat ...♕xh2#. The only move that comply both mission is 42. ♖xe3 because if Black would answered 42... ♖xh5 43.♖xe5 simply wins a ♘. The answer is forced as the combination continues: ♕xe3 43. ♕g6+ ♔f8 44. ♖f1+ ♔e7 45. ♘d5+. This is the kid! Any ♔ move lose the ♕, so he is forced to capture! Diagram. 45...exd5 
click for larger viewAfter this move, Black is dead!, with 46.♕f6+ ♔e8 47.♗g6+ ♘f7 (or ♖f7, it doesn't matter), 48. ♗xf7+, so now: 1)48... ♖xf7 (or ♘xf7) 49. Qxf7+ Kd8 50. c7#! A very beautiful check-mate!
2) 48... ♔f8 49. ♗g6+ ♔g8 50. ♕f8#
This is a rare case where all tatics is favourable. White must be very proud of this win! |
|
| Feb-04-22 | | King.Arthur.Brazil: The lonely problem, it is that Black would answer 44...♘f7 or 44...♖f7 and without the ♗ in g6, there's no victory of course... That's why the perpetual checks, folks!!! Sorry. |
|
| Feb-04-22 | | agb2002: White has two pawns for a knight.
Black threatens Rxh5 and aims at h2 and c3.
The black queen protects both knights, the dark squares around the king and the rook on h8 if the king moves. This suggests 42.Rxe3: A) 42... Qxe3 43.Qg6+ Kf8 44.Qf6+ (44.Rf1+ Rf7 and White looks lost, but not 44... Ke7 45.Nd5 exd5 46.Qf6+ Ke8 47.Qxh8+ Ke7 48.Qf8+ Ke6 49.Qf6#) A.1) 44... Nf7 45.Rd1 Kg8 (45... Ke8 46.Bg6 looks winning) 46.Qg6+ Kf8 (46... Kh8 47.Qh7#) 47.Qf6 repeats moves at least. A.2) 44... Rf7 45.Qxh8+ Ke7 46.Rd1 looks winning. A.3) 44... Ke8 45.Qxh8+ followed by Rf1 must be winning. A.4) 44... Kg8 45.Qd8+ followed by Qxc7+ is probably winning. B) 42... Rxh5 43.Rxe5 (threatens g4 and Bd1)
B.1) 43... Kf6 44.Rc5 and Black doesn't seem to have a decent defense against Ne4+ (44... Rh4(6) 45.Rf1+). B.2) 43... Kh6 44.Rf1
B.2.a) 44... Nh7 45.Rxh5+ Kxh5 46.Bxh7 wins a piece. B.2.b) 44... Nf7 45.Rxh5+ Kxh5 46.Rxf7 wins a piece. B.2.c) 44... Rh4 45.Rf6+ Kg7 (45... Kh5 46.Bd1+ Rg4 47.Bxg4+ -or 47.h3- 47... Kxg4 48.Rg6 wins) 46.Rg6+ Kf7 47.Rgxg5 Rxg5 48.Rxg5 Rxc6 49.Rg3 wins a piece. B.2.d) 44... Rxc6 45.Rf6+ (45.Rf8 Kg7, unclear) 45... Kg7 46.Rg6+ followed by Re3, unclear. B.3) 43... Rxc6 44.Bd1
B.3.a) 44... Kf6 45.Rxg5 Rxg5 46.Ne4+ Ke5 47.Rxc6 Kxe4 48.Rxc8 Rf5 (or 48... Rb5 49.Rc1) 49.Kg1 wins a piece. B.3.b) 43... Rh4 44.Rxg5+ Kf6 45.Rg3 Rhc4 46.Bb3 wins a piece. |

| | scormus: <Brenin> Thanks! My mistake and not for the first time. I really need 2 screens so I can work out and see the moves on one and type my comments on the other. My brain doesn't have enough RAM/processors to do it with only one screen. What I meant to write was 45 Qd8+ (not Qc8+, Qc7+ or Qd7+) Kg7 46 Qxc7+ Kh6 etc. The sequence wouldn't work for W if, instead of 44 ... Kg8, B played 44 ... Nf7 (e.g. 45 Rf1 Kg8 46 Qd8+ Kg7 47 Qxc7 (not+) Rxh2! which draws I think no mistakes between eye and fingers this time ..... but I won't bet my life on it! |
|
| Feb-04-22 | | AlicesKnight: I could see Rxe3 Qxe3; Qg6+ and nothing conclusive beyond that. Only later, looking again, did I notice that the game was drawn ... must pay attention, must pay attention, must pay attention ... |
