That's harder than a normal Monday.

  scutigera: Suction sac + skewer -- two tactics in one combo. A nice change from the usual queen-sac Monday: instead of a man sacrificing a female, a woman sacs a piece of architecture.

  agb2002: White has a bishop for a pawn.

Black threatens Ra1+ followed by the advance of the d-pawn.

The alignment of the black rook and the e-pawn on the a8-h1 diagonal suggests 52.Rxe4+:

A) 52... Kxe4 53.Bf3+ Ke3 54.Bxa8 d3 55.Bf3 + - [B].

B) 52... Kg3 53.Rg4#.

C) 52... Kf5 53.Rxd4 + - [B+P].

  perfidious: As <Lambda> noted, there are some finer points than usual for a Monday POTD than the typically straightforward solutions.
Jun-28-21  stacase: Took more than a few seconds to see it.

  Oxspawn: This was my Monday morning
52. Rxe4+ Kxe4 53. Bf3+ Ke3 54. Bxa8 d3 55. Bf3 d2 56. Kh2 Kf2 57. Bg4 Ke1 58. Kg3 d1=Q 59. Bxd1 Kxd1 60. Kg4 Ke2 61. Kxg5 Kf2 62. g4 Kg3 63. h4 and that point even I could not mess it up any more so black resigned.

  OhioChessFan: <Brenin: With moves like 48 ... Ke5? (Re8) >

I'm reasonably sure Re8 isn't better.

Jun-28-21  awfulhangover: This is a good Monday puzzle. Very easy, and not the typical Monday sac sac mate.
Jun-28-21  TheaN: On this less than usual Monday, the key move is obvious. <52.Rxe4+> leaves White with a won game in any variation. Main point is 52....Kxe4 53.Bf3+ +-, worst being 52....Kg3 53.Rg4#. Best is <52....Kf5 53.Rxd4 +-> given it allows some vague possibility to convert R+B vs R; of course no real practical way but it's Black's only chance.

There seems to be some question about the triviality of 52....Kxe4 53.Bf3+, but there's a ground rule here; White can retreat her bishop to f3 to prevent promotion, and because this leads to White being a pawn up there's no question as to how won this is: 53....Ke3 54.Bxa8 d3 55.Bf3 1-0 and Black's in the impossible choice of pushing d with a lost pawn endgame or sticking to g losing the piece down endgame.

Jun-28-21  saturn2: Additional thought for the free d pawn.
and that after Kg3 there is a mate threat.
Both rubbish.

They have ditched Stockfish and are making repairs to User: crafty.
Jun-28-21  goodevans: <Brenin: With moves like 48 ... Ke5? (Re8) and 51 ... Ra8?? (d3), Black threw away a win...>

You may be right about 49...Re8 [apart from the move no that is! ;o) ] but I don't think <51...d3> is any good. The trouble is that <52.Kf2> threatens 53.f3+ Kf5 54.Bg4#.

Black can only stop this by giving away another pawn after which the d-pawn is easily stopped.

I think Foisor was on the right lines trying to do some harassment with her R. If only she'd chosen 51...Rb8 rather than 51...Ra8.

  gawain: It's obvious that after 52 Rxe4+ Black cannot take the rook because of 53 Bf3+ leading to a won endgame. Nothing else gives Black any chance either. For a moment it looks like Black can try a mating swindle with 52...Kg3 53 Rxd4 Ra1+ but White has 54 Rxd1! and the rook is protected by the marvelous bishop. But wait. Black does not even get to try that: because after 52...Kg3 53 Rg4 is checkmate!

Crafty? Never heard of it. I thought Stockfish was the gold standard chess engine. Presumably they have some good reason for ditching a working feature of this site without putting in place its replacement. Wonderful web work there </sarcasm>

Jun-28-21  Nullifidian: 52. ♖xe4+ eliminates one of black's connected passed pawns, and if the rook is taken then 53. ♗f3+ king moves 54. ♗xa8 picks up the black rook and moving the bishop back with 55. ♗f3 will then control the d1 square.

If the rook isn't taken (52... ♔f5 is the only other viable move, since ♔g3?? ♖g4#), then the simple 53. ♖xd4 eliminates black's counterplay.

You can assume a </satire> tag at the end of <offramp>'s post.

Jun-28-21  DrWeevil: A few moments of confusion looking around for the queen...then it became obvious. A pleasing combination.

Woosh! You see, there is nothing so absurd that I wouldn't put it past chessgames.com to implement!
