Kibitzer's Corner
Dec-12-22  Brenin: 33 Rxe6 Rxe6 34 c5 wins a piece, with the Black Q tied to protecting against mate on g7.
Dec-12-22  jrredfield: I see this combination as winning the Black Q:

33 Rxe6 Rxe6 34 c5 Nf8 35 Qg5+ Kf7 36 Qg7+ Ke8 37 Qxc7.

According to the engine, 33 Rxe6 results in a mate in 15 with perfect play by White.

This is a Monday puzzle? Maybe it's me - perhaps I need to hit some chess 101 courses some more LOL.

Dec-12-22  sudoplatov: I came up with 36Rc6 followed by either Rxb6 or Rxe6. It wins but not as nicely.
Dec-12-22  Mayankk: I wanted to play c5 first, a potential line being 33 c5 Bxb3 34 Rxg6+ hxg6 35 Qh8+ Kf7 36 Qg7+ Ke6 37 Qxc7 with White up a Queen against Rook.

The idea for 33 c5 was that moving the e6 Bishop allows Rxg6 attack while saving the Bishop is not possible since Black Queen will get overloaded defending both the g7 square as well as this Bishop.

But as the game line is different, not sure if 33 c5 works.

Dec-12-22  Cheapo by the Dozen: This puzzle did a couple of headfakes.

First, it looked like there would be a quick mate.

Then, when that didn't work out, I found a way to perhaps win material.

And that only works because the Black queen becomes overloaded by ... a mate threat!

What's really tricky, by Monday puzzle standards, is that Black's queen doesn't start out having anything to do with e6.

And actually, I didn't realize until writing this post that there's yet another line -- 34 ... Kf7 defends against everything mentioned above, but fails to the skewer/x-ray of Black's queen via 35 Qxh7+.

Dec-12-22  goodevans: <Mayankk: I wanted to play c5 first... But as the game line is different, not sure if 33 c5 works.>

33.c5 was my choice too and SF confirms it's completely winning.

Got to admit I found this slightly harder than yesterday's Sunday 'insane' puzzle.

Dec-12-22  mel gibson: I chose 33. c5.

Stockfish 15 followed the game move:

33. Rxe6

(33. Rxe6 (♖d6xe6 ♖e8xe6 c4-c5 ♘g6-f4 c5xb6 ♕c7-d7 ♕h6xf4 ♔g8-f8 ♕f4xf5+ ♔f8-e8 b6-b7 ♖e6-b6 ♕f5-e5+ ♔e8-d8 b7-b8♕+ ♖b6xb8 ♗c3-a5+ ♖b8-b6 ♗a5xb6+ ♔d8-c8 ♕e5-c5+ ♔c8-b7 ♗b3-d5+ ♔b7-b8 ♕c5-f8+ ♕d7-c8 ♕f8-d6+ ♕c8-c7 ♕d6xc7+) +M15/52 38)

White wins _ mate in 15.

When I force SF to play my move the result is the same _ White wins mate in 15.

33. c5

(33. c5 Bxb3 (♗e6xb3 ♖d6xg6+ h7xg6 ♕h6-h8+ ♔g8-f7 ♕h8-g7+ ♔f7-e6 ♕g7xc7 b6xc5 ♕c7-c6+ ♔e6-e7 ♗c3-e5 ♖e8-a8 ♕c6-c7+ ♔e7-e6 ♕c7-d6+ ♔e6-f7 ♕d6-d7+ ♔f7-f8 a2xb3 ♖a8-d8 ♕d7xd8+ ♔f8-f7 ♕d8-d7+ ♔f7-f8 ♗e5-f6 e4-e3 ♕d7-e7+ ♔f8-g8 ♕e7-g7+) -M15/72 135)

White wins _ mate in 15.

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

The bishop on b3 x-rays the black king. This suggests 33.Rxe6 Rxe6 34.c5:

A) 34... Nf8 35.Bxe6+ Nxe6 36.Qxe6+ wins a piece.

B) 34... Qd(e,f)7 35.Bxe6 Qxe6 36.Qg7#.

C) 34... Kf7 35.Qxh7+ and 36.Qxc7 wins decisive material.

Dec-12-22  saturn2: 33 c5. and whatever black does with the Be6 - Bxb3 or move it to c8 or protect it by Qf7 o protect it by Nf8 he is lost

Many lines to look at though. Not very easy. 33.c5 Nf8 34.Qg5+ Kf7 (Ng6 35.Rxe6) 35.Qg7

  perfidious: Unlike others, gave no consideration to 33.c5; saw the forcing line actually played, which admits of no antidote.
Dec-12-22  sfm: Two bishops contemplating to point towards an open king with an open center. Time to worry as we have seen so many times. The path gets narrow for the defender.

Black earlier missed the tactical finesse 19.-,Ne5! (20.dxN??,Qc5+) 20.Qe2,Nxc4! 21.QxN,Rc8 22,Qb3,Bd5, giving him a slightly better game 19.-,e5 instead was still OK, though, but as it comes White has it easier.

23.-,gxR? supporting the center and giving a marchable f-pawn was still the wrong idea. Black can not stop Bb3 from becoming nasty as the c4-pawn can not be blocked. Such primitive arguments often needs sophisticated counters. Not there, or not found? Game over.

Those long enough in the game will know

Dec-12-22  sfm: White to move. At a glance it looks ok for Black, doesn't it?

Good establishment in the center, well-supported pieces. Maybe even good attacking chances, with f5-f4-f3 and e4-e3 also ready to go.

Nope. Surprising that it is so much over over already.

1) +4.52 (26 ply) 27.Rd1 Qc5+ 28.Bd4 Qe7 29.Bb3...

  Yogi Darwin: Seemed hard for Monday but, surprisingly, I got it anyway!
Dec-12-22  Refused: saw 33.Rxe6 instantly.

But since it's Monday I thought there had to be a fairly obvious quick mate somewhere, which I was missing.

Thus I spent another minute toying around with other moves, but since I didn't find anything better I went with

33.Rxe6 Rxe6 34.c5 +-

Premium Chessgames Member
  sjunto: Mate in 15. My move, 33. c5 , is mate in 16, according to Stockfish 12. Sometimes I hate these puzzles. At 61 ply Stockfish 12 calls 33. Rxe6 mate in 14. I fell asleep.)

I see what you're saying and, yes, to a patzer like me at first glance Black's central pawns look quite menacing. I guess that's what Black had in mind with <23...gxf6> and <26...f5> but a second look and the airiness around Black's K starts to look worrisome. Then when <27.Bb3> sees both of White's Bs aiming at that exposed monarch it becomes clear why White is so much better.

When you denude your K in such fashion you've got to be pretty certain that your own attacking chances are better than those you've just handed your opponent. In hindsight Black's 23rd and 26th were dreadful errors of judgement.

  scormus: I hope 33 Rxe6 Rxe6 34 c5 is good enough. It was enough for B, anyway. I wouldn't want to have to find the M15 to get full credit ;)
Dec-12-22  TheaN: <33.Rxe6 Rxe6 34.c5 +-> is curtains because Black has no way to prevent losing the rook via Bxe6+ (if the queen defends mate on g7 follows, and if the knight defends we can just hit on e6 twice), so goes a piece down at least. Apparently it's #15 with best play, but it wins.
Dec-12-22  AlicesKnight: Saw the Rxe6 - Rxe6; c5 succession (as others above) winning enough material to ensure the game. The bishop-pair is to the fore.
