  FSR: I tried to submit <Good Knight> for this game, but someone beat me to it.
Dec-21-18  nalinw: Seemed easier than the previous two days ....
Dec-21-18  mel gibson: That was easy.

  agb2002: White has two pawns for a knight.

Black threatens Rxe2 and Bxe1.

The obvious maneuver is 20.Qc4+ Kf6 21.Re6+ Kxf5 (21... Kf7 22.Rxc6+ Re6 23.Qxe6#; 21... Rxe6 22.Qxe6#) 22.d5:

A) 22... Rxe6 (or 22... Nf6) 23.Qf4#.

B) 22... Qc7 (or 22... g5, 22... Bd2, 22... Bd6) 23.Qe(g)4#.

C) 22... cxd5 23.Qg4#.

Dec-21-18  ACMEKINGKRUSHER: WOW,
Not BAD for a 451 Point Rating Difference! Just by chance I happened to look it up! Congrats to SIMON!! AKK
Dec-21-18  Mayankk: I got the first two moves in a jiffy but struggled to spot 22 d5.

I wonder what is it with the simple pawn moves that I forget to evaluate them in the midst of tactical fights.

Dec-21-18  areknames: Definitely not Friday standard.
Dec-21-18  latebishop: Mayankk-Yes seeing 22.d5 is the challenging part in visualising the mate I think.
Dec-21-18  areknames: Unusual to see a GM murdered like this by an untitled player.
Dec-21-18  ChessHigherCat: Took me a little while but I think this works:

20. Qc4+ Kf6 21. Re6+ Kxf5 22. Rxe8 Rxe8 23. Qf7+ Ke4 24. Qxe8+ Kf3 (Kxd4 is kamikaze-ville) 25. Qe3#

Dec-21-18  ChessHigherCat: Whoops, missed the defense 23...Nf6. <Mayankk> I looked at d5 but didn't see the follow-up.
Dec-21-18  Eduardo Leon: Not that difficult.

<20.♕c4+ ♔f6 21.♖e6+ ♔xf5>

21...♖xe6 22.♕xe6#

<22.d5!>

Black cannot simultaneously stop both threats 23.♕f4# and 23.♕e4#.

Dec-21-18  stacase: <<Mayankk: I got the first two moves in a jiffy but struggled to spot 22 d5.> latebishop: Mayankk-Yes seeing 22.d5 is the challenging part in visualising the mate I think.>

Same here I spent the most time on 22.d5 But then you had to make that first move, 20.Qc4+, in the puzzle correctly as 20.Pxg6+ was quicker to spot. But as one of those little tips you see when you post says, <"When you see a good move look for a better one">, definitely applied in this case.

Too easy for a Friday? Yeah, I thought so but then at my level Chess is sometimes just plain dumb luck and you stumble on coming up with the best move (-:

  Richard Taylor: I found the moves. I forgot though that Qf4 was mate and calculated Qg4 which also wins. But I saw Qf4 mate in all other lines or Qg4 mate.

Reasonably straightforward. Quite a beautiful attack by White.

Dec-21-18  Walter Glattke: Prolongue mate possible with e.g. 22.-Qxf2+ 23.Kxf2 Bc5+ 24.Kg2 Bd4 25.Qd3#
Dec-21-18  Walter Glattke: 22.d5 threatens 4 mates: Qe4/f4/g4/d3
Dec-21-18  siggemannen: 17...Kf8 seems better

  malt: Have 20.Qc4+ Kf6 21.Re6+ K:f5 22.d5 cd5
23.Q:d5+ Ne5 24.Q:e5#

Noticed 23.Qg4# later.

Dec-21-18  gofer: 20 Qc4+ Kf6 (Re6 Qxe6#) 21 Re6+ Kxf5 (Rxe6 Qxe6#)

At this point, there are probably lots of solutions. But one grabbing lots of bits seems to be...

22 Rxe8 (threatening Qf7#) Rxe8
23 Qf7+ Ke4
24 Qxe8+ Kf4/Kd4 (Kxd4 Be3+!)
25 Qxd7+ +-

Black escapes for a few more moves, but is a whole rook down and its probably time to resign...

~~~

<Doh!> 22 d5 is much cleaner!!!

Dec-21-18  Walter Glattke: gofer: 23.-Nf6

  thegoodanarchist: Simon says "checkmate!"
Dec-21-18  eyalbd: Qc4+ and Re6 are obvious. The key move is d5! with deadly threats on the 4th rank. Not too difficult to find.

  Breunor: Also missed d5! I think I would have made the first two moves instinctively, maybe I would then have found d5 but I didn't see it from the beginning.
