  al wazir: Easy.
Feb-19-20  landshark: Miffed on this one.
Feb-19-20  Boerboel Guy: Simple.
Feb-19-20  ASchultz: Interesting and pleasing mating pattern. It seems like the knight on d6 has to do SOMETHING, but it can't do anything immediate.

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

White can attack the black king with four pieces, starting with 36.Rxg7+ Rxg7 (36... Ka8 37.Rb8+ Ka7 38.Nc6#) 37.Nc6+ Ka8 38.Nc7+ Rxc7 39.Rb8#.

  boringplayer: Very nice. I missed it, but very nice.
Feb-19-20  Walter Glattke: Arabic mate also possible with 36.Rxg3 hxg3 37.c6 Bxd4+ 38.Nxd4 wins, if 38.-bxc6, then 39.Nxc6+ Ka8 40.Rb8# 36.Rxb7+ Forces that.
Feb-19-20  Damenlaeuferbauer: After long pondering, my old French friend Igor finally found the mate in 4 moves and sacrificed first a rook for a pawn and then a whole knight with 36.Rxb7+!,Rxb7 (36.-,Ka8 37.Rb8+,Ka7 38.Nc6#) 37.Nc6+,Ka8 38.Nc7+!,Rxc7 39.Rb8#. He played the best game of his entire career 2 years earlier against the British GM John Nunn, a Sicilian Kalashnikov Maroczy Bind with the black pieces, which got the brilliancy price from the Informator.
Feb-19-20  malt: Have 36.R:b7+ R:b7

(36...Ka8 37.Rb8+ Ka7 38.Nc6# )

37.Nc6+ Ka8 38.Nc7+! R:c7 39.Rb8#

Feb-19-20  TheaN: As I just posted on yesterday's puzzle, the Tuesday and Wednesday this week don't compare at all and a swap would have been appropriate. CG, try to uphold that standard.

<36.Rb7+ Rxb7 (Ka8 37.Rb8+ Ka7 38.Nc6#) 37.Nc6+ Ka8 38.Nc7+ Rxc7 39.Rb8#>. Nothing less, but definitely nothing more either.

Feb-19-20  TheaN: Actually I do have something more: in the case of 36....Ka8, what's the boredom in mating in two, if you can let this pleasing mate arise:

36.Rxb7+ Ka8 37.Nc7+ Rxc7 38.Rb8+ Ka7 39.R1b7+ Rxb7 40.Nc6#

Feb-19-20  Cheapo by the Dozen: I was so focused on queening pawns I missed the outright mate. :(
Feb-19-20  griga262: This was much easier than yesterday. At least, I hit the winning line right away. Maybe, just lucky to look in the right place first.

Feb-19-20  takchess: It's fun when you have a lot of material to throw away to reach checkmate.
