 | | al wazir: 41. Rxf6+ Kxf6 42. Kd5 was obvious.
What to play after 42...bf4 was not. What happens after 45...d3 46. Nxd3 Kd4 ? 43. Nxc5 Bxd2 (43...Rxc5+ 44. Kxc5 Bxd2 45. Kxd4 a5 46. a3) 44. Ne4+ Ke7 45. Kxc6 Bc3 looks tempting. |

 | | agb2002: The white king is under check.
The lack of movement of the defenseless black rook suggests 41.Rxf6+ Kxf6 42.Kd5 Bf4 (42... Rc8 43.Kxd6 followed by either Kxc5 or Bxc5) 43.Kxc6 Bxd2 44.Nxc5 (44.Kxc5 Be3 seems to give Black some chances): A) 44... Ke5 45.b4 followed by b5 looks winning (45... Bxb4 46.Nd3+ and 47.Nxb4). B) 44... Bb4 45.Nd3 a5 46.Kd5 Bc3 47.a3 followed by b4 is winning. |

Sep-19-19 | | Walter Glattke: Only option was 42.-Rc8 43.Kd6 Re8 44.Nxc5 Re2 45.Bb4 Rxa2 46.Kd5 Rh2
but white should win either. |

Sep-19-19 | | patzer2: For today's Thursday puzzle, I found the first four moves of the combination 41. Rxf6+! Kxf6 42. Kd5 Bf4 43. Kxc6 Bxd2 44. Nxc5 +-. However, after 44...Ke5 I didn't see anything better than 45. Nxa6 +-. Stronger and more clever is the game move 45. b4!, creating a passed pawn on the b-file by threatening a decisive Knight fork. P.S.: Black's decisive mistake was 40...Nf6+? allowing 41. Rxf6+! +- (+5.04 @ 30 ply, Stockfish 10). Instead, 40...Bf8 41. Kd3 Rd8 42. Bc1 Bd6 43. Ke4 a5 = (0.00 @ 36 ply, Stockfish 10) holds it level. |

Sep-19-19 | | 1stboard: Rubean Fine -- The King us a strong piece , use it ! And white did to win .....
Nice ending with a poison pawn to win. |
|
Sep-19-19 | | 1stboard: If white plays 43 Bxf4 instead of the text move does it win ? B+N vs R What does Stockfish say on this ? |
|
Sep-19-19 | | charlesdecharemboul: I agree whit WorstPlayerEver. Not so easy. |

Sep-19-19 | | mel gibson: Black's Rook is trapped as the Black King is overloaded
by the text move.

You don't have to do all that lookahead if, instead of your 45...d3 46. b5, you simply play 45...d3 <46. Nxd3+> Kd4. 47. Nc5 Bxb4 48. Nxa6 with two pawns up and what looks like a technically simple win. click for larger viewAm I wrong? |

Sep-19-19 | | TheaN: It's basically comparing winning concepts here in either a +B, N+BvR or NvB endgame. After <41.Rxf6+! Kxf6> (here Black really has no alternative or go the bishop down) <42.Kd5>. Black can solve this kingfork in two ways: move the rook on the c-file or play Bf4: other bishop moves make no sense on account of Kxc6. After 42....Rc8 43.Kxd5 +- White has to be wary of the d-pawn but the rook has no easy access and the queen side pawns go fast after N/Kxc5. If instead <42....Bf4> White has a choice. I guess the risk-free endgame <43.Kxc6 Bxd2 44.Nxc5 +-> is the safest for White with no chances of losing. However, 43.Bxf4 wins too, as 43....gxf4 +- the f-pawn's dangerous but stoppable, after 43....Re6!? White has to be a bit careful but 44.Nxc5! +- decides. |
