Jan-06-11		Calar: The threat is Rh1 + Rh8#, I assume?

Jul-11-23		Brenin: 46 Rxg6 fxg6 47 Kxg6, and 48 Rh1, 49 Rh8+ are lethal (47 ... Kg8 48 f7+)

Jul-11-23		jrredfield: 46 Rxg6 was pretty obvious, but how to proceed? If 46 ... fxg6, then 47 Kxg6 Kg8 48 f7+ Kf8 49 Kf6 Ne8+ and mate soon for White. So Black appears to have ways to stall the inevitable mate as long as possible. Perhaps 46 ... Rd8 or 46 ... Ne8, but all roads lead to disaster for Black, so it doesn't seem to matter. I think OTB as Black, I would resign.

Jul-11-23		PawnSac: Right. Here's the full line... 46. Rxg6 fxg6 47. Kxg6 Kg8 48. f7+ Kf8 49. Kf6! and if Ne8+ (not 50.fxe8=Q but..) 50. Nxe8 Rxe8 51. Rg1

Jul-11-23		PawnSac: keep the K in the mating net

Jul-11-23		Mayankk: For a change, I saw the main line of 46 Rxg6 fxg6 47 Kxg6 almost immediately. It took a while to realise how helpless Black is, although White needs 2 moves to activate its remaining Rook via 48 Rh1 and 49 Rh8#. One potential line I played out was A) 47 ... Kg8 48 Rh1 A.1) 48 ... Rf8 49 Nf5 Rf7 (to prevent Ne7#) 50 Nh6+ picking up the Rook A.2) 48 ... Ne8 49 f7+ Kf8 50 Rh8+ Ke7 51 f8=Q+ A.3) 48 ... Rd8 49 f7+ Kf8 50 Rh8+ Ke7 51 Nf5+ Kd7 52 Rxd8+ and 53 f8=Q+

Jul-11-23		takebackok: Good puz, once you see the a1 rook going to h1 and the black king traped!

Jul-11-23		An Englishman: Good Evening: My word, the Black King becomes astonishingly helpless, doesn't he?

Jul-11-23		Refused: 46.Rxg6 fxg6 47.Kxg6 and it's dead. Black has no defense against 48.Rh1

Jul-11-23		King.Arthur.Brazil: This is the only thing I see (then, many will do the same): 46. Rxg6 fxg6 47. Kxg6 Ne8 48. Ne6+ Kg8 49. f7+ Kh8 50. f8=R# Other way is: 47... Rc8 48. Ra7 Rb8 49. f7 Ke7 50. Nf5+ Ke6 51. Rxb7 Rxb7 52. f8=Q Nb5 53. Qe8+ Re7 54. Qxe7#. If 51... Rc8 52. Rxc7 (Black captures, then f8=Q). Also 49... Ke7 50. Nf5+ Kd7 51. Rxb7 Rf8 52. Kg7 and Black is lost.

Jul-11-23		PawnSac: < jrredfield: So Black appears to have ways to stall the inevitable.. Perhaps 46...Rd8 or 46...Ne8, > well, yea, but it's all an exercise in futility. It's like watching stockfish work out the best defense all the way to checkmate when down a queen! lol OK think of it this way.. click for larger view This is the position with white to move. White is up the exchange. Well, black has a knight and pawn for the rook. Now.. white plays Rxg6 assuming ..fxg6 Kxg6 and we have this.. click for larger view white has returned the material advantage; given back the R for N+P in order to gain a choke-hold on the black K. This is the whole point of the puzzle. Could black forestall the inevitable? Of course, as can the loser in many of the puzzle positions, but it's just a matter of technique. For example: < perhaps 46...Rd8 > After 46...Rd8 47.Rg2 we have this.. click for larger view and now black is down a whole rook with no compensation. It's game over, no analysis necessary. A 2300 player could beat a super-GM at classical time control with the white pieces. It's just a matter of technique. So load this position, or ones like it, in SF and give yourself an hour, and beat the engine! Learn the technique.

Jul-11-23		mel gibson: I could see that Black was busted. White needed to get a Rook to Black's back rank. 46. Rxg6 was one way. Stockfish 16 says: 46. Rxg6 (46. Rxg6 (Rg2xg6 Rb8-d8 Rg6-g1 Rd8-d6 Ng7-h5 Kf8-e8 Rg1-g8+ Ke8-d7 Rg8-f8 Kd7-e6 Ra1-f1 Nc7-a6 Nh5-g7+ Ke6-d7 Rf8xf7+ Kd7-c8 Rf7-f8+ Kc8-d7 Kh6-h7 Kd7-c7 Ng7-e8+ Kc7-b6 Ne8xd6 Kb6-a5 Rf8-f7 Ka5-b4 Rf7xb7+ Kb4-c3 Nd6-f5 c6-c5 d4xc5 Kc3-d2 b3-b4 d5-d4 e3xd4 e4-e3 f6-f7 e3-e2 Rf1-a1 Kd2-d3 c5-c6 Kd3-c4 b4-b5 Na6-b4 Rb7-b8 Kc4-d3 c6-c7 Nb4-c2 Ra1-c1 Kd3-d2 Rc1xc2+ Kd2xc2) +16.45/40 641) score for White +16.45 depth 40. When Black resigns it's mate in 6: 47. Kxg6 Kg8 (Kf8-g8 f6-f7+ Kg8-f8 Kg6-f6 Nc7-e8+ Ng7xe8 Rb8xe8 Ra1-g1 Re8-e6+ Kf6xe6 c6-c5 Rg1-g8+) -M6/221

Jul-11-23		agb2002: White has a rook for a knight and a pawn. White can attack the black king, starting with 46.Rxg6 fxg6 47.Kxg6 followed by Rh1: A) 47... Ne8 48.Rh1 A.1) 48... Nxg7 49.Rh8#. A.2) 48... Kg8 49.f7+ Kf8 (49... Kh8 50.Rh8#) 50.Rh8+ wins. A.3) 48... Nxf6 49.Kxf6 wins decisive material. B) 47... Rd8 48.Rh1 Kg8 49.f7+ Kf8 50.Rh8+ Ke7 51.Rxd8 Kxd8 52.f8=Q+ wins. C) 47... Ra8 48.Ne6+ Kg8 (48... Nxe6 49.Rxa8+ Nd8 50.Rxd8#; 48... Ke8 49.Nxc7+) 49.f7+ Kh8 50.Rh1#.

Jul-11-23		AlicesKnight: The gameline was not too hard to see with the threat of Rh1 in some form to come.

Jul-11-23		Teyss: Not so obvious for a Tuesday because of Black's potential defences: look at the lengths of our favourite kibitzers' posts. After a not-so-obvious Monday, this will be a long week.

Jul-11-23		perfidious: Another out of the ordinary early week POTD, with Black being curiously helpless after 46.Rxg6 fxg6 47.Kxg6 in the face of Rh1 and Rh8.

Jul-11-23		NM JRousselle: 46 Rh1 also does the trick. If 46... Nh8 then 47 Kh7 wins easily.

Jul-11-23		Lambda: I found a very pretty move in my main line: 46.Rxg6 fxg6 47.Kxg6 Kg8 48.f7+ Kf8 49.Kf6 Rd8 click for larger view 50.Ne6+! Nxe6 51.Rh1
