  fredthebear: This leads to Mayet's Mate pattern, but it is also called Anderssen's Mate pretty much anytime a rook in the corner is protected from behind along the diagonal. Various classic chess book sources give one name or the other.

Jan-02-23  jrredfield: Truly a beginner's puzzle. 39 Qh8+ Bxh8 40 Rxh8 mate.
Jan-02-23  jrredfield: How Black missed 34 ... Bxe5 I can't understand. Was it a rapid game? 34 ... Bxe5 and Black is well ahead. 34 ... Re8 simply leads to an even game.
Jan-02-23  Messiah: Way too easy!

<fredthebear> beware of the approaching <stone dumb or die>/<idiotissimus> think tank for referencing Mayet's mate.

Jan-02-23  Mayankk: Queen sac Mondays are back. Black King is stuck in a corner with few escape squares. So 39 Qh8+ Bxh8 40 Rxh8#.

White's response to 32 Nd5 was instructive. Instead of moving the endangered e5 Rook, it offers another piece via 33 Nxe6. And then mates in 7 more moves.

Jan-02-23  Cheapo by the Dozen: Heavy piece sacrifice on the h-file for a quick mate.

Now THAT'S a Monday puzzle!

Jan-02-23  Brenin: 30 ... Nc3 or 30 ... Bxe5 31 Rxe5 Nc3 would have given Black a winning position. Later, Black needed to play 36 ... e5 or 37 ... e5 to stay in the game. A marginally less trivial puzzle would be White's 38 Qh7+, with mate to follow.
Jan-02-23  Mayankk: Another pretty mating pattern on the same theme arises if Black plays 37 ... e5 and the game goes on like

37 ... e5 38 Bxe5 Nf6 39 Bxf6 Rxe2 (Black takes offered Rook) 40 Qh7+ Kf8 41 Qh8+ Bxh8 42 Rxh8#.

  takebackok: No think no look queen sac Monday...and its good!
Jan-02-23  stacase: 39.Bxd7+ was nonproductive. The usual Monday Queen sacrifice did the trick, cute mate.
Jan-02-23  mel gibson: That's too easy even for beginners.
Jan-02-23  Allderdice83: After 33 Nxe6, how about 33 ... Bxe5 34 Qxe5 f6? Stockfish 15 gives this position as +1.39 for White. However, the continuation I thought of, 35. Qe4 Rh7 36. Qxg6+ Kh8 with the idea of generating Black's own mate threats, fails to several possible responses, the best and most spectacular of which is 37 Nd8!! (blocking the Black rook and threatening Re8+) and if 37 ... Rxd8, then 38 Bxf6+ Nxf6 39 Qxf6+ winning the rook on d8 and setting up a mating pattern. Instead, Black should play 35 ... Ne7, and then 36 Qh4 f5 37 Qxf6 Rh7 38 Qxg6+ Ng7 39 Re4 Qxb3.
Jan-02-23  AlicesKnight: Monday and Q-sac time. It works because the b2 B guards the g7 square while the Black castle walls keep the K in. So Qh8+ followed by Rxh8#
Jan-02-23  Vermit: He who blunders next to last wins

  perfidious: As Tartakower wrote so long ago, the winner of the game is the player who makes the last but one mistake.
Jan-02-23  agb2002: White has two pawns for a knight.

Black is about to play Ke8.

The bishop controls g7. Therefore, 39.Qh8+ Bxh8 40.Rxh8#.

Jan-02-23  Damenlaeuferbauer: After long thinking, the strong English GM and Sicilian (dragon) specialist Gawein Jones finally found the mate in 2 moves with the nice queen sacrifice 39.Qh8+!,Bxh8 40.Rxh8#. I wish every true chess player out there a happy new year 2023, especially a lot of health and success in the royal game!
Jan-02-23  TheaN: <39.Qh8+ Bxh8 40.Rxh8#>. Interestingly, the fianchetto'd bishop is normally a huge thorn in the king side attack: biggest issue is that after an eventual h-file break, the bishop's covering h8 and the king can usually escape to f8 after a check on h7. Key to that is though, do not block off e7...

White was playing optimistic but faulty: focused too much on the attack. Before Black delayed fianchetto'd he had a chance to deliver a killing blow with 30....Nc3!, discovering on d4 with the idea 31.Bxc3 Bxe5 -+ and White's forced between two evils (take on e5 and lose c3 or the opposite). Not an easy combo to see to be honest. 30....Nf6? = was okay defensively: 32....Nh7! ∓ would have been the better discover, Nd5 allowing Nxe6 with complications. 34....Re8? throwing away another win (just Bxe5! -+).

The finale is probably even worse from both sides: 36....Qb6?? throws the game due to 37.Qh7+ Kf8 38.Bxg7+ Rxg7 39.Rf5+! +- (again, not easy to see). White lets Black back with 37.Re2, after which 37....Ree7 38.Qh7+ #2 seals the game's fate.

Tl;dr: Black created the strong defensive bishop, had the chances to diffuse the attack a couple of times but didn't. End result, mate in 3 from White.

Jan-02-23  TheaN: <jrredfield> Looking at it myself, I can understand Carlsson avoiding 34....Bxe5 35.Rxe5:

Requiring 35....Kf8! 36.Qxg6 Rh7! ∓ to -+ a rook up is risky. Having said that, if you are being offered an exchange a piece up, worth to consider if the additional rook can assist in defending the position. This is defendable, so this should have been Black's choice.

Jan-02-23  Dohboy: Literally took one second to solve.

Jan-02-23  jrredfield: <TheaN> Good thoughts. I checked with SF which shows 34 ...Bxe5 as gaining at least a +3 advantage whereas the text move left Black with only drawish possibilities. That was a big swing in the game when Black definitely would have had winning chances.

Jan-02-23  King.Arthur.Brazil: Truly Monday: 39. ♕h8+ ♗xh8 40. ♖xh8#. The King recommends 37...Nf6. Time to <Brenin> says something... HNY to him too.
