 | | al wazir: 44. Kh1. Now what?
If 44...Rh7, then 45. Be1 Rh3 46. Rbb2. Black is a ♙ up and the white ♔ is in a rather drafty corner, but that's all. |

 | | al wazir: <Gregor Samsa Mendel: I think after 44 Kh1 Rfg7 45 Be1 Rg2 it's all over.> Well, it's not quite all over, but I agree that it's resignable.: 44. Kh1 Rfg7 45. Qc1 Rg2 (45...Rh3 46. Bf4 exf4 47. Qxf4) 46. Rxg2 Rxg2 (46...fxg2+ 47. Kg1) 47. Bf4 exf4 48. Qxf4 Rg4. Thanks. |
|
Apr-20-21 | | Refused: 43...Rxg3+ is lights out.
a) 44.fxg3 Rh7 curtains
b) 44.Kh1 Rfg7 is curtains.
to answer al's question
sample line.
44.Kh1 Rfg7 45.Qc1 Rg2 46.Rxg2 Rxg2 47.Bf4 Qg4 and rien ne va plus the main threat is Rxh2+ Qg2# if white tries to plug the g-file with Bg3 simply Rxg3 and in case of 48.Rb2 f2 looks good enough. |
|
Apr-20-21 | | saturn2: There is a slower win by 43...e4
A. after bishop moves black gets an impressive pawn chain 44. Bc1 e3 45. Ra2 f2+ 46. Kg2 Qf3 B. 44. dxe4 Ne5 followed by Ng4 and f2 |

 | | drollere: 43. .. Rxg3+, 44. hxg3 Rh7, 45. Bh6 Rxh6 leaves white no way to prevent mate. |
|
Apr-20-21 | | Brenin: 43 Kg1 is a blunder, leading to the obvious sac 43 ... Rxg3+, and time trouble seems to be no excuse. Then both 44 hxg3 Rh7 and 44 Kh1 Rfg7, threatening Rg2, are hopeless for White. Playing 43 Qg1 would have allowed White to survive a little longer, though 43 ... e4 makes life very uncomfortable for him. |
|
Apr-20-21 | | Walter Glattke: 44.Bf1 Rg2 45.Rbb2 found no mate, stockfish, where are you now, when everything goes wrong somehow.? (seems I am chessblind this morning) |
|
Apr-20-21 | | Walter Glattke: Ah, Qxh2# |
|
Apr-20-21 | | goodevans: Black sac's a R so can White save the game by giving up his? I got as far as 43...Rxg3+ 44.hxg3 Rh7 45.Rg2 Qh1+ 46.Kf2 fxg2 47.Qg1 Rf7+ 48.Ke2 Qh5+ 49.Ke1 Rf1+ before deciding that that was it for White. Seven moves deep is quite tough for a Tuesday. |

Apr-20-21 | | mel gibson: The first ply was obvious but
I couldn't see a quick checkmate.
That is correct as Stockfish 13 says:
43... Rxg3+

 | | agb2002: Black has a knight for a bishop.
The pawn on h2 blocks Qh1# after Rh7. This suggests 43... Rxg3+: A) 44.hxg3 Rh7
A.1) 45.Rg2 Qh1+ 46.Kf2 fxg2
A.1.a) 47.Qxg2 Rf7+ 48.Bf4 (48.Ke2 Qxg2+ wins) 48... Qxb1 wins decisive material. A.1.b) 47.Qg1 Rf4+ 48.Bf4 (48.Ke2 Qh5+ 49.Ke1 Rf1+ wins decisive material) 48... exf4 wins a piece. A.2) 45.Re2 Qh1+ 46.Kf2 Rh2+ 47.Ke1 Rxe2+ wins.
A.3) 45.Rxf3 Qh2#.
B) 44.Kh1 Rfg7, with the threat Rg2, looks winning. |

Apr-20-21 | | stacase: Very straight forward and very easy. |
|
Apr-20-21 | | AlicesKnight: I found the gameline and the main points after 44.Kh1 Rfg7. Major piece crush..... |
|
Apr-20-21 | | TheaN: Takes some time to see whether White has an escape, but <43....Rxg3+> is clear. White's best off to not play 44.hxg3 given 44....Rh7 and White has no escape. Sample lines are 45.Rxf3? Qh2#, 45.Re2 Qh1+ 46.Kf2 Rh2+. I will say I missed the potential of 45.Rg2 (giving back what we were given) but 45....Qh1+ 46.Kf2 fxg2 -+ kind of follows the ideas of Re2. <44.Kh1 Rfg7 -+> and it's done, as Rg2 will inevitably follow with a undefendable threat on h2. |

Apr-20-21 | | 1g1yy: <stacase: Very straight forward and very easy.> Agreed, with a caveat. I"m still new to getting back into the game. Even a month ago there were days on a puzzle as easy as this, after I saw the solution, I'd think holy cow was that easy (but I didn't see it, or got a move sequence wrong). So even after only a short time studying basics and tactics puzzles, I'm seeing things like this much faster. I had this in seconds, not that that's anything to a stronger player, but at my level it's encouraging being able to quantify my progress. Especially when I can see it in my rating and puzzle scores increasing rapidly. I don't get em all yet, but after seeing my own progress even in a month or two, I see the value in studying these situations, often. |

 | | Jimfromprovidence: The puzzle gets tricky after 43...Rxg3+ 44. hxg3 Rh7 45. Bh6 Rxh6 46 Rfb2, below. click for larger view 46...f2+ 47 Kxf2 Rf6+ wins, but there are way better moves out there for those interested in looking for them. |
|
Apr-20-21 | | Brenin: In <Jimfromprovidence>'s position above, 47 Rxb7 is an empty threat in view of 47 ... Qh2#, so why not let Black's Ps and/or N join the attack with 46 ... e4? If 47 dxe then 47 ... Ne5 stops 48 Qc4+ and threatens 48 ... Ng4 followed by 49 ... f2+. White can try to run with 48 Kf2 but then 48 ... Qg4 and 49 ... Qxe4 looks very strong for Black. OTB, though, I would probably have taken the more obvious route 46 ... f2+ 47 Kxf2 Rf6+. |
