Aug-25-15  tanu123: I like that 15.Bh6 sacrifice very much.Amazing game,wonderful attack but only players are unknown.
Aug-25-15  zb2cr: 29. Rg7+! does it. If 29. ... Bxg7; 30. Qe6#. If 29. ... Ke8; 30. Qg6+, Rf7; 31. Qxf7#.
Aug-25-15  roentgenium: Like other people who have posted, I did eventually find and correctly evaluate Rg7+, but only after considering other moves such as Qg6+, Qh7+, Qh5+, and even ideas of bringing a Rook onto the e-file (I even considered whether the knockout blow might be Kf2 or Kd2). In a real game, I would probably need at least several minutes on my clock to find this mate.
Aug-25-15  dfcx: with the current position, it would be mate if the white queen were on e6. This suggest the first move:

29.Rg7+! Ke8 (Bxg7, 30.Qe6#) 30. Qg6+ Rf7 31.Qxf7#

  offramp: Today's winning move is 29. Rg7+.

After 29...Bxg7 then 30.Qe6 is a typical <offramp mate>.

After 29...Bxg7 then 30.Qe6 is a typical <offramp mate>.>

No offense to you, since you thought up a fantastic name for this mate, but IMO it should be called "The Trident Mate".

My justification is that the Queen controls 3 lines: the rank, the file and the diagaonal, that are available for the King' movement.

Like the 3 prongs of a trident, the Queen's power stabs at the enemy King along all 3 lines.

Aug-25-15  CHESSTTCAMPS: The most brutal form of a dovetail mate is Cozio's Mate, found in the article:

The winning side is down a pawn, with both pieces placed on squares close to lowest possible mobility. The kind of ending where intuition and general principles can lead you to - defeat.

Aug-25-15  kevin86: If the bishop takes, white has an epaulette mate at e6 with the queen.
Aug-25-15  Alex56171: <Moonwalker: Got it. However, would one of the more capable kibitzers please help me understand where black went catastrophically wrong? Was it 14...h6 ?>

By Stockfish, 14....f5 would equalize.
After 15.Bxh6 Qb6 16.Ra3, it sees white better (+0.84 depth=36).

  offramp: <thegoodanarchist> Trident mate sounds much better than dovetail mate.

In any case, there certainly deserves to <be> a trident mate.

Aug-25-15  starry2013: I don't know the pattern so I suppose the lesson on this puzzle is just sacrifice a piece (the queen sac not available here) and see what option is there. I was going for more normal checks with the queen, but not forcing enough apparently as I saw no route to win easily.

  offramp: I think it should be called a Good Anarchist mate.

It actually makes sense!

Aug-25-15  BOSTER: <Moonwalker: where black went wrong?>

Certainly move 14...h6 is a <lapse>.

But after 16.Qxh6 black should play 16...e4-it is always a good idea to lure the opponent's piece where it can be attacked.

After 17.Bxe4 Nf6-defence h7 square and attack the bishop e4.

Now white has to spend 4 tempo to chase the knight f6 playing g4-g5, take away the bishop e4,and take away the king from open file.

So, black has enough time to defend his king playing Re8,Bf8,Nbd7 and so on.

Aug-25-15  Nullifidian: 29. ♖g7+ ♗xg7 (♔e8 30. ♕g6+ ♖f7 31. ♕xf7#) 30. ♕g6+ ♔e7/8 31. ♕e6#
Aug-25-15 It took me a bit of time to solve it, but I made it. A good visualization exercise, in that if the B vacates f6, it clears the way for Qe6 mate.

Aug-25-15  lost in space: 30. Rg7+ and game ends here
Aug-25-15  Moonwalker: Thanks <M.Hassan>, <Alex56171> and <BOSTER>. I guess the take away message is that black's under development (no pieces below the 7th rank) and lost tempos may be more problematic than any single move.

  eternaloptimist: It took me a little while to figure it out but once I saw 29.♖g7+, I saw that the ♕ can deliver checkmate quickly after that.
Aug-26-15  thegoodanarchist: <offramp: I think it should be called a Good Anarchist mate.

Well, far be it from me to contradict your towering intellect!

Using the adjective at the beginning allows us to taylor the name of the mate to the player.

He or She who delivers the mate will call it the <Good> Anarchist mate.

The player on the receiving end will substitute another adjective for <Good>.

This should be readily apparent to the user.

Aug-26-15  thegoodanarchist: And adding to my previous post, the player on the receiving end might substitute an adjective that begins with <effing>.

Don't worry, I have hear them all before :)

May-07-19  KingMJA: Aww..a true Tuesday level puzzle. Rg7+!
Ke8...Qg6+ and mate next.
May-07-19  NBZ: Took me several minutes to see Rg7+! None of the "normal" ways to proceed, such as Qh5+, Qg6+, Qh7+ seem to work as Black inconveniently gets in Be7/Be5 (though I'd hazard White is better in all of those lines).
