May-26-17  Walter Glattke: Ah, the finesse here is 31.Rh3, so 30.-Kg7 would win with all other moves, 31.Qg5+ Kh8 32.Bg6 Rg7 etc.
May-26-17  morfishine: got the first two moves

Black threatens Qxc2.

White can take advantage of the weak light squares around the black king with 29.Rxf5+:

A) 29... exf5 30.Qxf5+

A.1) 30... Ke7 31.Qf7+ Kd8 32.Qxg8+ Kd7 (32... Ke7 33.Qf7+ Kd8 34.Qe8#) 33.Bg4+ Kc6 34.Bxc8 + - [R+2P].

A.2) 30... Kg7 31.Rh3

A.2.a) 31... Qxc2 32.Qf7+ Kh6 (32... Kh8 33.Bg6#) 33.Bd1+ Kg5 34.Rh5#.

A.2.b) 31... Rc(g)f8 32.Qg6+ Kh8 33.Be2+ Qh7 34.Q(R)xh7#.

A.2.c) 31... Qc3 32.Qg6+ Kh8 (32... Kf8 33..Qf7#) 33.Bd3#.

A.2.d) 31... Rgd8 32.Qg6+ Kf8 33.Rf3+ and mate in three.

B) 29... Ke7 30.Rf7+ Kd8 (30... Ke8 31.Rxc7+ wins) 31.Qh4+ and mate soon.

C) 29... Kg7 30.Rxe5 (probably better than 30.Rf7+ Qxf7 31.Bxf7 Rxc2)

C.1) 30... dxe5 31.Qxe6 (with the double threat Rd7+ and Rg3+)

C.1.a) 31... Qxc2 32.Rd7+ and mate in two.

C.1.b) 31... Rcd8 32.Rg3+

C.1.b.i) 32... Kf8 33.Rxg8#.

C.1.b.ii) 32... Kh7 33.Bg6+ and mate soon (33... Kg7 34.Bf7+; 33... Kh6 44.Rh3+ Kg7 45.Rh7+ Kf8 46.Rf7+).

C.1.b.iii) 32... Kh8 33.Qf6+ Rg7 (33... Kh7 34.Bg6+ and mate in three) 34.Rxg7 Qxg7 (34... Rd1+ 35.Bxd1) 35.Qxd8+ wins.

C.2) 30... Qxc2 31.Rg3+ Kf8 (31... Kf6 32.Q(R)xe6#) 32.Rxg8+ Kxg8 33.Rg5+ Kf8 34.Qf3+ Qf5 (34... Ke7 35.Rg7+ Kd8 36.Qf8#) 35.Rxf5+ wins.

May-26-17  Iwer Sonsch: 29.Rxf5+ exf5 (what else?) 30.Qxf5+ Ke7 (30...Kg7 31.Qg6+ Kf8 32.Rf3+ Ke7 is no better) 31.Qf7+ Kd8 32.Qxg8+ wins back the rook.


May-26-17  Iwer Sonsch: Oh, I missed that 30...Kg7 31.Qg6+?? Kh8 32.Qh6+ was not mate.

  Richard Taylor: Good attack by White. I missed 30. ... Kg7 but my excuse is I was a bit drowsy after a big dinner (and of course, OTB, coffeed up, I would have found everything, given I had enough time...well, I would have found "everything" in a correspondence game, in the old days,...well...I would have found it all with a computer...) and I then found (without a machine), on going back for a rethink the Rh3 idea. Which was the key move. Very clever play by White.

A ferocious attack by White...a typical Najdorf with both players trying to attack each other....White threw everything at Black and perhaps Black had defence somewhere...but entertaining chess...!

May-26-17  malt: 29.R:f5+ ef5 30.Q:f5+ Ke7 31.Qf7+ Kd8 32.Q:g8+ Kd7 33.Bg4+ Kc6 34.Q:c8 or 34.B:c8
May-26-17  et1: Rh3 was the trick
May-26-17  thegoodanarchist: <rodchuck: Hoo Phlung Dung?>

LOL, that was hilarious!

Premium Chessgames Member
  kevin86: White's offense is there, black's defense is not!
Premium Chessgames Member
  kevin86: Hippo game is highly ineffective for black.
May-26-17  whiteshark: Black missed the hedgehog spirit

  ChessHigherCat: 25. Nd5 was some dung well flung! I guess if exd5 Qxf5, with thum heavy thit an nguyen
May-26-17  Chesstorian72: Took me a minute to find every move, I'm better than everyone here!!
May-26-17  swclark25: got first two moves like <morfishine>, but then looked at 31)Rg3+

following game line, would Black have been better with 31)...Rcf8 to move White Queen and threaten Rf1+ ?

Looking closer looks like ..Rcf8 would have closed f8 as an escape from Qg6+, so nevermind.

May-26-17  Walter Glattke: Looking into the game, 25.Nd5 wins by threatening Rf7 later, 14.-Nb4! 14.-Na5?? is the Chinese Snooker here, so as one kibitzer ask for.
May-26-17  morfishine: <swclark25> A subtle finesse nuance, very nice, almost like a full fledged waiting move


May-26-17  RandomVisitor: After 28...dxe5

<0.00/49 29.Rfd1 Ke7 30.Qe3 e4> 31.Qc5+ Qxc5 32.Rd7+ Kf8 33.Rf7+ Ke8 34.Rg7+ Kf8 35.Rf7+

May-27-17  patzer2: Since (29. ?) is supposed to be a fairly difficult Friday puzzle, it wasn't hard to guess the first couple of moves 29. Rxf5! exf5 30. Qxf5+.

However, after 30...Kg7 finding the paralyzing follow-up 31. Rh3!! was the difficult part of this puzzle.

The threatening but non-checking, non-capturing 31. Rh3!! is the kind of move one of my favorite posters, <Once>, calls a Goot (Get out of that) move. For me, "Goots" are generally the most difficult moves to find in a combination, especially when one is a piece down.

After 31. Rh3!!, it's rather easy for White to find 31...d5 32. Qg6+ Kf8 33. Rf3+ Bf4 34. Qf6+ Qf7 35. Qxf7#.

Black's game starts to falter after 26...Ne5 27. dxe5 to (+0.60 @ 27 depth, Stockfish 8.)

Instead, Black can hold it level with 26...Rh8! when strong play might continue 27. c4 Rh7 28. dxe6 fxe5 29. Bxf6 Nxf6 30. Qe3! Nxh5 31. Qxe6 Re8 32. Rxf5+ Rf7 33. Rxf7+ Qxf7 34. Qxd6+ = + (0.00 @ 34 depth, Stockfish 8.)

May-29-17  Nova: <patzer2> and <Once> is there a GOOT game collection (perhaps put together from POTDs)? If not someone should start one!
May-30-17  patzer2: <Nova> I took your suggestion and started a GOOT game collection with this game's 31. Rh3!! being the first entry.
