Mar-14-07  Eurotrash: quite easy puzzle, but would be hard for me to see OTB I think.
Mar-14-07  uuft: Found it immediately.

Pretty hard to miss imho, considering black's attacking powder is nowhere, and anything but Rf5+ (except Rh5+) is not forcefull enough, coz it's wednesday. What's more: we had not had a rook sac for a day, too! lol

Mar-14-07  Rubenus: Beautiful mate but a bit too easy for Wednesday, more like Tuesday.
Mar-14-07  mkrk17: Happy i got it..although i took around 3-4 minutes to get it..

Anyway..nice puzzle...and good going by Barua

Mar-14-07  zb2cr: I didn't see the correct follow-up to the Rook sacrifice. After some 3 minutes I gave up. Very tricky mating pattern with the Knight and the Rook; didn't see it as I'm most familiar with the Knight supporting the Rook mate in a corner.
Mar-14-07  tatarch: This ending must have left black a little shell-shocked--sure it's easy enough to find when posted as puzzle of the day, but OTB this would catch most players with their pants down.

  playground player: For those who still don't see the finish: 32. Rf5+, gxf5 33. Rg7+, Kh6 34. Nxf5#, ta-dah! It's all forced, so Black has to resign.
Mar-14-07  YouRang: I got it, and I'm quite pleased with myself! :-)

The black king was so confined, that there had to be some trick to force mate. A knight often comes in handy to deliver mate in confined situations, but the knight was not in checking range, it it was busy guarding the pawn on g4.

The Rf3 was the only piece that didn't seem to have a role to play in confining the king, so I got the idea of sacrificing it with 32. Rf5+ to force open the g-file for the other rook. After the forced 32...gxf5, we have 33. Rg7+, which gives us what we need: while guarding Pg4, it also forces the king to be confined on a different square (33...h6), where 34. Nxf5 guards the rook and delivers mate.

Very nice coordination of pieces!

Mar-14-07  Ashram64: Rf5+.. looking for mating attack is easy.
Mar-14-07  kevin86: It's funny: I found the key move with the idea that after 32... gxf5 33 ♖g7+ ♔h6 34 ♘f5+ followed by ♘xd6 forking the rooks-I overlooked the fact the ♘f5 was checkmate!

Instead of a brilliant series of forks-we have something better:a brilliant checkmate!

Mar-14-07  pggarner: Took me a while to see the check on g7; kept looking at giving check with Rh5 or Rf5 after sacrificing the other rook, but then the knight couldn't give the final check.
Mar-14-07  NakoSonorense: The first move that came to mind was Rh5+, but after I could not see any winning combination, I looked at Rf5+ and voila!
Mar-14-07  Themofro: Got it, seemed to just be staring me in the face, although i initially checked Rh5+ first.
Mar-14-07  Happypuppet: What is it called when in a checkmate every square is controlled by one piece? A perfect mate? Here's one.
Mar-14-07  Dagobert2: I saw 32. Rf5+ and the rest of the attack immediately. I think I'll call it a week while I'm ahead.
Mar-14-07  simsan: I also got this one. I saw the same potential fork that kevin86 described, but - when evaluating where the king would go after 34 Nf5+ - realized that it was in fact 34 Nf5# ;-)
Mar-14-07  libertyblues: I finally got one. Instantly, even.
32. Rf5+ gxf5 33. Rg7+ Kh6 34. Nxf5#
beautifully forced
Mar-14-07  YouRang: <Happypuppet: What is it called when in a checkmate every square is controlled by one piece? A perfect mate? Here's one.> I've never heard the term "perfect mate", but it's an interesting idea.

But is this really an example if it? It seems that two squares are controlled by the knight: (1) h6 (attacking the king) and (2), g7 (guarding the rook).

Mar-14-07  chesstoplay: Easy as a puzzle,

but over the board, I don't know...

If I was way up on time, maybe.

Mar-14-07  beginner64: Missed it by miles.

OTB I would be whimpering for a draw in this position that I wouldn't even consider a rook sac.

I guess I will turn in for the week :-)

Mar-14-07  sanyas: <YouRang> Not "every piece controls one square" but "every square is controlled by one piece". The squares adjacent to the Black king are h7 (rook), g7 (knight), g6 (rook), g5 (rook), and h5 (pawn). Of course the h6 square counts too; there is only one piece checking the Black king: a knight. So it is a perfect mate. I think it's problem terminology. Another good example of a perfect mate is the final position in Nimzowitsch vs Tarrasch, 1914.
Mar-15-07  YouRang: <sanyas> Thank you -- I see now that I misunderstood the meaning. So then, even something like this would be a perfect mate:

Mar-17-07  Happypuppet: Found where I learned of it. It's called a clean mate as spoken of on this page: A Steinkuehler vs Blackburne, 1863
Mar-19-07  zb2cr: <Happypuppet>,

That's funny--I had heard problem composers called this kind of position--where each square is controlled by one piece--a "pure" mate.

Jun-09-20  Arjan S: At move 31 Barua missed a mate in 4: 31.Rf5+ Kh6 32.Rh5+ gxh5 33.Nf5+ and 34.Rg7#
