Kibitzer's Corner
Dec-28-18  Walter Glattke: No escape, Nh7+ is the key, totally breakdown, 29.-Ke8 30.Qxg6+ Ke7 31.Qe6#, 29.-Ke7 30.Qxg6 Rd6 31.Rxe5+ Kd8 32.Qe8#
Dec-28-18  Mayankk: I thought it was pretty simple and the answer was Qxg6 as fxg6, Nxg6 is a pretty mate.

Unfortunately Black doesn’t have to accept the sacrifice. Talk about misplaced illusions...

Dec-28-18  ChessHigherCat: 28. Nxg6+ fxg6 29. Nh7+ Ke7 30. Qxg6 Bd5
leads to this position by force, where it's a challenge to find a move that doesn't win for white:

Dec-28-18  devere: Nice combination, but pretty easy to see. The only wrinkle is to avoid 28.Qxg6?! Ra6!, and Black stands better! "When you see a good move, look for a better one." Lasker

Instead of 30...Qxc5 Black can try Rd5 (to try to save both King and Queen), but then might follow 30...Rd5 31. Qxg7+ Kd8 32. Qf8+ Kd7 33. Nf6+ Kc6 34. Qxh6 Kxc5 35. Ne4+ Kxc4 36. Rc1+ and White wins the Black Queen anyway.

Dec-28-18  AlicesKnight: I found the key first three moves; it seems ....Qc6 is no help after 31.Qxg7+ Ke8; 32.Nf6+ winning the Q, so Benko plays a help-mate.
Dec-28-18  mel gibson: It looked pretty easy.
I saw the first 3 moves.

Stockfish 10 says mate in 32.
That's the longest sequence I've seen for a while. I'm using a hashtable of 8 Gigabytes.

Chessgames, why don't we forget using symbols for pieces! Letters are better.

I just copy & paste it directly from
an Arena interface file put into "Notepad".
It's this website that turns the letters into symbols of pieces.

Yes - I would prefer that it was written in a long list of each numbered move but no one would pay me to do that.

Every move is actually there.

  agb2002: White has a bishop and a knight for the bishop pair and a pawn.

Black threatens Nxc2 and Bxf6.

White has Nxg6+ and Qxc6.

In the case of 28.Nxg6+ fxg6 29.Nh7+ (29.Qxg6 Nd5 looks unclear) 29... Ke7 (29... Ke8 30.Qxg6+ and mate next) 30.Qxg6:

A) 30... Rf8 31.Qxg7+ Kd8 32.Qxf8+ wins.

B) 30... Kd7 31.Qe6#.

C) 30... Re8 31.Qe6+ Kd8 32.Rxd4+ B(N)d5 (32... exd4 33.Qxe8#) 33.Rxd5+ N(B)xd5 34.Qxd5+ Kc8 (34... Ke7 35.Qe6+ Kd8 36.Rd1+ and mate soon) 35.Qxa8+ Kd7 (35... Qb8 36.Qc6+ Kd8 37.Rd1+ wins) 36.Qd5+ Kc8 (36... Ke7 37.Qe6+ Kd8 38.Rd1+ wins) 37.Ra1 or 37.Ba6+ wins.

D) 30... Bd5 31.Qxg7+ Ke6 (31... Ke8 32.Nf6#) 32.Qxc7 wins.

E) 30... Nd5 31.Qxg7+ Ke6 32.Qxc7 wins (the knight is pinned, or 32.Bxd5+ and 33.Qxc7).

F) 30... Rd5 31.Qxg7+ Kd8 32.Qxc7+ Kxc7 33.Bxd7 B(N)xd5 34.Rxe5 + - [R+2P vs B].


In the case of 28.Qxg6:

A) 28... fxg6 29.Nxg6#.

B) 28... Bxf6 29.Qxf6

B.1) 29... Nc6 30.Ng6+ Ke8 (30... Kg8 31.Qh8#) 31.Nxe5 looks crushing.

B.2) 29... Nd5 30.Ng6+ Ke8 31.Rxe5+ wins.

B.3) 29... e4 30.Be6 (threatens 31.Ng6+ and mate next)

B.3.a) 30... Ke8 31.Ng6 fxg6 (31... fxe6 32.Qxe6+ Qe7 33.Qxe7#; 31... Qxc5 32.Qh8+ Qf8 33.Qxf8#) 32.Qxg6+ Kf8 (32... Ke7 33.Qf7#) 33.Qg8+ Kf7 34.Qf7#.

B.3.b) 30... Kg8 31.Ng6 fxe6 32.Qh8+ Kf7 33.Qh7+ Kf6 34.Qxc7 wins decisive material (34... Kxg6 35.Qxb7).

B.4) 29... Bd5 30.Ng6+ Ke8 31.Rxe5+ Be6 (31... Kd7 32.Re7+ wins) 32.Rxe6+ wins (32... fxe6 33.Qxe6+ Qe7 34.Qxe7#).

C) 28... Nd5 29.Bxd5 Bxd5 (29... fxg6 30.Nxg6#; 29... Rxd5 30.Nxd5 fxg6 31.Nxc7 wins a rook) unclear.


I think I'd play 28.Nxg6+.

Premium Chessgames Member
  Jimfromprovidence: Beside avoiding 28 Qxg6 as <devere> noted, white also has to avoid 29 Qxg6, below, as well.

The threat is 30 Nh7+ with mate next move but here black gains a tempo and can interpose with 29...Nd5, below.

Now 30 Nh7+ is no good because black's king has an escape square on g8. Also 30 Bxd5 is met by 30...Bxd5 or 30...Rxd5 so that is no help to white.
