Oct-19-22 | | Brenin: Black is going to find Qe4 and Qh4 mate hard to stop, except by Nxf5, so eliminate the N with 36 Rxe3 Bxe3 (otherwise Black is N+2P down) 37 Qe4 Bg5 (what else?) 38 Nxg5 Kxg5 39 Qh4+ Kxf5 40 Bh3+ Ke4 41 Qf4+ Kd5 42 Bg2+ with mate to follow. |

Oct-19-22 | | catlover: I guess a likely finish is: 37...Qd1+ 38. Rxd1 Rxd1+ 39. Bf1 Rxf1+ 40. Kg2 Rf2+ 41. Kh3 Rxf5 42. Qxe3+ Kh5 43. g4# |

Oct-19-22 | | mel gibson: I chose a different move.
36. Qc1
which still wins but not as strong - see below.

|
Oct-19-22 | | jrredfield: <mel gibson> I also chose 36 Qc1. I failed to see that with the position resulting from 36 Rxe3 Bxe3 37 Qe4 threatening Qh4 that the Black King was seriously limited in mobility and had to sac the Bishop. But Qc1 still wins as does 36 g4 and 36 Qe4. |
|
Oct-19-22 | | Cheapo by the Dozen: I found this pretty quickly. I also considered reversing the move order, but the calculations got hairy. The engine agrees that the game move was best, even though the reversed order also wins big. |
|
Oct-19-22 | | saturn2: I had the two game moves. Then black can cause some scare on the backrank but white will prevail.with plus material. 37...Qd1+ 38.Rxd1 Rxd1+ 39.Bf1 Rxf1+ 40.Kg2 g5 41.Kxf1 |
|
Oct-19-22 | | King.Arthur.Brazil: The king doesn't see the immediate reason to resign. Some lines: A) 37...g5 38. ♕xe3 ♖g8 39. h4 ♕e7 40. hxg5+ ♖xg5 41. ♕xg5+ ♕xg5 42. ♘xg5 ♔xg5 43. ♖f1 ♖d2 44. ♗xb7 ♖xb2 45. ♗xa6 ♔f6 46. ♗b5 ♖b3 47. ♖f3 ♔e5 48. ♔g2 or B) 37...♗g5 38. ♕g4 ♕e7 39. ♕h3+ ♗h4 40. ♕xh4+ ♕xh4 41. gxh4 gxf5 42. ♘d4. Yes, white has material but still a long way to win. |
|
Oct-19-22 | | King.Arthur.Brazil: The wining line is: 37...♗g5 38. ♘xg5 ♔xg5 39. ♕h4+ ♔xf5 40. ♗h3+ ♔e5 41. ♖e1+ etc. If Black doesn't capture g5, 37...♗g5 38. ♘xg5 gxf5 39. ♕xf5 ♖f8 40. ♕g4, I guess white has a winning attack here. Good night folks. |

 | | beatgiant: <King.Arthur.Brazil>
A) 37...g5 <38. Qg4> and how to stop 39. Qh3# next? B) 37...Bg5 38. Qg4 Qe7 39. Qh3+ Bh4 <40. gxh4> gxf5 41. Qe3+ Kg6 42. Bf3 leaves White with both material and a huge king hunt. |
|
Oct-19-22 | | boringplayer: I went with 36.Qe4 straight away. Missed 36...Nf5. No credit today :( |
|
Oct-19-22 | | raymondhow: I picked 36 g4, saw that mate would follow if Q taken. |
|
Oct-19-22
 | | scormus: 36 Rxe3 Bxe3 looked obvious to me.
Then I wanted 37 Qe4 to set up the finish.
But wait, better look at ... Qd1+ 38 Rxd1 Rxd1+ 39 Bf1 Rxf1+ 40 Kg2 Rg1+ or Rf2+ Is that a problem? No, 41 Kh3.
37 Qe4 it is.
Oh, I see B then resigned anyway |
|
Oct-19-22 | | Refused: 36.Rxe3 Bxe3 37.Qe4 curtains (double threat of Qh4# and Qxe3 is a bit too much). 37...Bg5 38.Nxg5 Kxg5 runs into 39.Qh4+ Kf5 40.Rf1+ (of 40. Bh3+ also works) Ke6 41.Bh3+ Kd5 (Ke5 42.Qg+) 42.Rd1+ is probably the line White should be able to calculate. |
|
Oct-19-22 | | saturn2: <boringplayer: I went with 36.Qe4 straight away.issed 36...Nf5. No credit today :> You found a good move.
37.Bh3 yields the win. |

Oct-19-22 | | TheaN: <raymondhow: I picked 36 g4, saw that mate would follow if Q taken.> I'm with <raymond> on this one, and I'd say it's a solve, albeit it's a bit of a sophisticated line: <36.g4!?> definitely wins but requires more work from White than at first glance. Obviously, the point is 36....Nxc2? 37.g5+ Kh5 38.Bf3+ Kh4 39.Re4+ Qf4 40.Rxf4+ Kh3 41.Bg2#. So Black will have to find an alternative: <36....g5>. Now, White no longer has Rxe3 with Qe4 as the g-file's blocked. Pile on for the mate: <37.h4!>, still: 37....gxh4? 38.g5+ Kh5 39.Bf3+ Ng4 40.Bxg4+ (I had Rg2 here initially, still mates, but I'd reconsider in a game) Kxg4 41.Qe4+ Qf4 42.Qxf4+ Kh5 43.Qf3#. However, after <37....Rg8>:

The attack seems to grind to a halt. Only now did <38.Qe4> seem like a good move to me and it wins, though slowly, after <38....Qg3 39.hxg5+ Rxg5 40.Nxg5 Kxg5 41.Qf3 +-> and Black can't really prevent material trades and the endgame is easily won. Still, quite a tough line for a Wednesday, but I like it. |
|
Oct-19-22 | | Brenin: Like <raymondhow> and <TheaN> I was also initially tempted by 36 g4, in view of the rather pretty mate after 36 ... Nxc2. However, I rejected it on account of 36 ... Nxg4, not seeing that 37 Bf3 wins. |
|
Oct-19-22 | | TheaN: 36.g4 Nxg4 is indeed a bit of an issue that I underestimated, mainly the direct mate threat on h2. 37.Bf3 wins, where 37.Qc1+? seems like a trap it still holds for White. 37....Be3, obviously, as Black's threatening mate on h2, 38.Qxe3+ Nxe3 39.Rxe3 and White's threatening mate: 39....gxf5 40.Rg1!
 click for larger view
And all of a sudden the White pieces are stronger than the Black queen, requiring the otherwise insane 40....Kg6!, allowing White to force 41.Bd5+ Kf6 42.Nf4 threatening Nh5# and Re6+: 42....Qxd5+! 43.Nxd5 Rxd5 44.b3 = and Black has a minimal plus in the endgame. |

Oct-19-22 | | agb2002: White is two pawns up.
Black threatens Nxc2 and Nxf5.
These threats and the airy position of the black king suggest Rxe3 and g4. In the case of 36.Rxe3 Bxe3 37.Qe4:
A) 37... Bg5 38.Qg4 Qe7 39.Qh3+ Bh4 40.gxh4 wins decisive material. B) 37... g5 38.Qg4 wins.
C) 37... Qd1+ 38.Rxd1 Rxd1+ 39.Bf1 Rxf1+ 40.Kg2 Rg1+ 41.Kf3 wins. -----
The alternative 36.g4 is interesting (36... Nxc2 37.g5+ Kh5 38.Bf3+ Kh4 39.Re4+ Kh3 40.Bg2#) but after 36... g5 matters become more complicated than in the case of 36.Rxe3. |

|
Oct-19-22 | | Cheapo by the Dozen: So basically White loaded up against e6, and Black didn't see the danger. E.g., Stockfish thinks 27 ... Rd6 could have kept Black's position playable. |
|
Oct-19-22 | | Halldor: I went for 36 Rxe3 (since Qc1 seemed too slow for my nerves). 36 Rxe3 Bxe3 37 Qe4 Bg5 38 NxB KxN 39 Qh4† Kxf5 40 Rf1†. Here, a ghost of the Rook that I sacrified on the e-file at start was still there in my mind, it happens sometimes, but anyway — without that ghost Rook on the e-file mate is still imminent. |
