  sneaky pete: Some websites and the ChessCafe quiz masters erroneously claim this game is the subject of Méry's poem "Une revanche de Waterloo". It is not.

What inspired Méry was

A weak white pawn easily overlooked
At his square in front of the king's knight;
...
With a double step, jumping forward from his corner,
He cries to the black king: you won't go far!

That's about 29.g4# in the 17th game of the (first) match La Bourdonnais vs MacDonnell, 1834.

  notyetagm: Position after 28 ♖g5-h5+!:


click for larger view

A lovely example of <SQUARE CLEARANCE>. White would be able to play ♕e5-g5# if only his White g5-rook was not already on this square.

<<<Note that Black is doing -nothing(!)- to stop this threat; -only- the White g5-rook being in the way is preventing the <SNAP MATE>.>>>

So White simply moves his White g5-rook off of the g5-square with a <FORCING MOVE>, 28 ♖g5-h5+!, and Black is powerless to stop the mate next move with 29 ♕e5-g5#.

Result of vacating g5-square for White e5-queen:

De La Bourdonnais 2 mistakes:

27...Bg4 #2 (27...Rf5 7.87)

Feb-01-12  Knight13: Makes me wonder if Black's mucho-ducho opening of the Kingside was brave or stupid. Very likely the latter.
Oct-04-21  Brenin: If the White Q could capture its own piece, then 28 Qxg5 would be mate. It can't, but White can remove the R with 28 Rh5+, and then (after 28 ... Bxh5 or Kg6) 29 Qg5 mate.

  Cheapo by the Dozen: It's a Monday puzzle, and a heavy piece is being sacrificed on the h-file.

That said, this is a somewhat unusual form of a pure clearance sacrifice.

Oct-04-21  Brenin: Alternative puzzle (a little harder than Monday standard): suppose that Black had played 27 ... Rf6 instead of Bg4. Find the win for White.
Oct-04-21  stacase: Spent a little time on searching for a Queen sacrifice - Monday you know, and then I looked at the Rook. Ha! Forced mate in two (-:
Oct-04-21  Steve.Patzer: Even I could see that.

  Gregor Samsa Mendel: Probably one of those positions where McDonnell said, "I don't like it muchy."

  agb2002: White has an extra pawn.

The rook on g5 avoids Qg5#. Hence, 28.Rh5+ and mate next.

  drollere: doesn't get simpler than that. <27 ... Rf6 instead of Bg4.> 28. Bxf4 <nimh (27.Bxf4 #6)> 27. Bxf4 Rxf4, 28. Rxe6+ Qxe6, 29. Qg7#

  Dionysius1: I prefer 28.Rg8 instead of <drollere>'s 28.Bf4 as solution to <Brenin'>'s alternative puzzle. There are more juicy ways forward. E.g. 28...Rxg8 29.Qxf6 Rg6 30. Bf4 Kh5 31.Re5+, then Black throws away pieces blocking on f5 and White mates on h3

Oct-04-21  Brenin: <drollere>:After 27 ... Rf6 instead of Bg4, did you mean 28 Bxf4 Rxf4 29 Qxe6+ (Rxe6+ is impossible)? Then 29 ... Qxe6+ 30 Rxe6+ R(either)f6 avoids mate. White is 2P up, but still has work to do. There is a better solution after 28 Bxf4 Rxf4.
Oct-04-21  goodevans: Very nice game by the guy with the long name.

  Messiah: Nice! Thank you for this puzzle!
Oct-04-21  TheTamale: A rule I use to solve Monday puzzles is to look for the move you'd like to play, and that's often it. Then you figure out how to make it work.

  drollere: i was thinking more 27. .. Rf6, 28. Bxf4 Rxf4, 29. Rh5+ Kg6, 30. Qg5+ Kf7, 31. Qxf4+ . although Rg8 is exceedingly sexy.

  raymondhow: It's a nice Monday puzzle. McDonnell's bio here claims he was "of GM strength". Is that for real, or was that some enthusiastic Irishman's opinion?
