Jul-15-16  morfishine: Remarkable series of moves
Jul-15-16  Doniez: I had only rough idea of the first moves but the development of the game was wonderful
Jul-15-16  JohnBoy: Four things:

1) I missed the lovely 29.ed5

2) Nice catch by whiteshark on 38, although it's not evident that black has better than 37...Rb8

3) Black may be able to hold it together after 29...Qf8 30.Rg4+ Kh8. This does seem to keep material even after either 31.Nf5 or 31.Qf8+ Nf8 32.Nf5 Bd5

4) It seems that 25...d5 was the howler, as it invited the c2 bishop into the fray.

Jul-15-16  cocker: The weekend started early.
Jul-15-16  WorstPlayerEver: First time in months I had to analyse with the computer. Got 26. Nf5 but then lost track. Seems that after 39. d6 Black could have resigned.
Jul-15-16  WorstPlayerEver: PS I promote this game to 'insane' as suggested by others in this thread; take a look at the following line (which was the line I struggled with):

26. Nf5 Nh5 27. g4 Qf6 28. Ng5 d4 29. Qh7 Kf8 30. Qh5 gh5 31. Nh7 Kg8 32. Nf6 Nf6 33. Nd6 Be6 34. Ne8 Re8

Jul-15-16  nalinw: <7he5haman>

30 .... Qf8
31 Nxf5 Qxh6
32 Nxh6+ Kf8
33 Nxg4 Bxd5

White has only a better position - material is equal.

Jul-15-16  catlover: Tough puzzle. I didn't even get the idea, much less the first moves.

  agb2002: White is one pawn down.

The dark squares around the black king are weak and the black queen is not protected. The rook on a3 is ready to incorporate into attack. These details suggest 26.Nf5, clearing g3 with tempo:

A) 26... gxf5 27.Nh4

A.1) 27... Qc5 28.Rg3+ Ng4 (28... Kh8 29.Qg7#) 29.Nxf5 Qf8 30.Rxg4+ Kh8 31.Rg7 wins decisive material.

A.2) 27... Qd6 28.Rg3+ Ng4 29.Qxd6 wins.

A.3) 27... Nf8 28.Nxf5 Ne6 (28... Nh5 29.Qxc6 wins) 29.Rg3+ (or 29.Qxf6 + -) and mate soon.

B) 26... Nh5 27.g4 (27.Ng5 Ndf6 28.Bd1 or 28.Rg3 are interesting)

B.1) 27... gxf5 28.Qxc6 wins.

B.2) 27... Re6 28.Ng5

B.2.a) 28... gxf5 29.Qxh7+ Kf8 30.Qxf7#

B.2.b) 28... Ndf6 29.Nxe6 wins an exchange.

B.3) 27... Ra6 28.Nd4 exd4 29.gxh5 gxf5 (due to 30.Qg7#) 30.Rg3+ wins decisive material.

B.4) 27... Qc5 28.Ng5

B.4.a) 28... Ndf6 29.gxh5 gxf5 (29... Qxa3 30.Qg7#) 30.Rg3 looks winning (30... Kh8 31.Ne6 + -; 30... f4 31.Ne6+ and mate next; 30... Qf8 31.Ne6+, etc.).

B.4.b) 28... Nf8 29.gxh5 gxf5 30.Rg3 is similar to B.4.a.

Jul-15-16  Tiggler: I got the double knight sacrifice, but then I missed the best defense, which is 27. ..Qc5, as played. I expected that the black Q would have to stay on the 6th rank with ..Qb6 or ..Qa6. 28.Nxf5 is then a killer.

Remarkably strong play by white until 38.Qxc4, when my engine confirms the suspicion that 38.Qc7 with Qxf7 to follow would have ended the game faster.

Jul-15-16  Tiggler: <devere> That line after 28. ..Qf8 is a lot better for black than the game. Still should be lost, though.
Jul-15-16  NBZ: I found the double knight sacrifice, but only after first messing up the move order! Nd4 straightaway allows Qc5! going back to f8 to defend. So White must first play Nf5 and only then Nd4, so that the Black queen cannot go back to f8 to defend.

Having said that, I did not find exd5. That is a crazy move to see in the original position, and it's difficult enough even when the position is staring you in the face.

  perfidious: Black could have spared himself the finish after his opponent cut off the king with his 57th move.

  drollere: black is up a pawn and threatens d4, but has no immediate attack on the white king.

white threatens the classic Ng5, which is thwarted by the black N at f6, supported by the N at d7.

the white bishop at c2 is blocked by the pawn at e4. the N at f3 is tied to protecting the R at e1, but the N at g3 has no defensive role and forces capture at f5. the white R at a3 is blocked by the N's, and mate would follow Rg3 if the black pawns were out of the way. so:

26. Nf5 f5
27. Nxd5 Nxd5
28. Rg3 Ng6

and that combination fails, so i don't solve the puzzle.

the game solution, Nd4, works because it does not pull the N at d7 into play.

30. Bxe4 is pretty, since the knight must be captured (31. Nxf5 forces mate; 31. Bxf5 would allow the rook capture on e1, but the white rook cannot be captured because the pawn on f5 is pinned by the bishop).

everything that follows from 34 is improvised around the fact that white has two separate mating threats (g7 and h7).

i thought Rh4+ had potential, and opened up a K flight square ... but what do i know.

Jul-15-16  araodin: May I suggest, respectfully, a pun in portuguese for this game? [Eu] me garanto. Translating: [I] guarantee myself.
Jul-15-16  NBZ: <WorstPlayerEver>

Hmm, after 26. Nf5 Nh5, I wonder if white should play 27. Ng5 right away. Then if 27. ... Nf6/f8 28. g4 wins the knight on h5; if 27. ... Qf6 28. Rf3 and I cannot see a good way for Black to defend against all the threats.

  Jimfromprovidence: I kind of liked 30 Rxe4 instead of the text.

It sets up the mate threat 31 Rxg4+, forcing 30...Rxe4 followed by 31 Bxe4.

White has a very strong position, with black's f5 pawn and g4 knight pinned.

Jul-15-16  NBZ: <Jimfromprovidence> Interesting! Then if Black plays 31. ... Qxd4 (in the last diagram that you posted), 32. Rxg4+ Kh8 33. Bxf5 Qa1+ 34. Kh2 Nf8 is very similar to the game, except the white pawn is on f2 rather than f4.
Jul-15-16  WorstPlayerEver: @NBZ Guess you are right. 26. Nf5 Nh5 27. Ng5 Ndf6 seems pretty aesthetic to me.
Jul-15-16  mel gibson: I never saw this one - it's too hard.
Jul-15-16  RandomVisitor: After 25...d5

Jul-16-16  7he5haman: <nalinw> you missed out the moves in your original post:

<<30. Rxg4+ Kh8

but then?? The White Knight is still hanging and the Queen is attacked.>>

I want to play Nxf5 *after* 30...Kh8, *not* after 29...Qf8, which was clear in my original post, given that I wrote 31.Nxf5 and not 30.Nxf5.
