Feb-15-16  agb2002: White is one pawn down.

Black threatens 21... Qd5+.

The pawn on e6 is hanging and the knight is very close to Black's royal family. These details lead to 21.Bh6+:

A) 21... Kxh6 22.Nf7+ Kg7 23.Nxd8 Rhxd8 24.Rxa6, etc.

B) 21... Kg8 22.Qxe6#.

Feb-15-16  jith1207: I love the continuing end game where the White queen picks up the compensation for the sacrificed minor pieces to go one full queen up.

General Rule:

In proximity to the enemy Horse,
Watch out for the filthy Forks!
Damn, it be a Royal,
Y'all end up in Denial.

Feb-15-16  dfcx: Took longer than usual to find the solution for this Monday POTD, because the move is not a usual queen/rook sac.

21.Bh6+ Kxh6 (Kg8? 22.Qxe6#) 22.Nf7+ forks royally.

Feb-15-16  patzer2: Got today's Monday solution basics with 21. Bh6+ Kxh6 22. Nf7+ .

However, I didn't calculate all the way to mate after 22...Kh5 (22... Kg7 23. Nxd8 ) 23. Qf3+ Ng4 24. h3 g5 25. hxg4+ Kg6 26. Ne5+ Kg7 27. Qf7+ Kh6 28. Rh1#.

One of Black's last best chances at improvement might be replacing 11...c6 with 11...Qd5+ 12. Kg1 Be7 = (-0.06 @ 21 depth, Deep Fritz 15).

Feb-15-16  stst: Marvelous config...and B-sac:

21.Bh6+ ....
IF (A) .........KxB, 22.Nf7+ forks Q & R, Q lost
IF (B) .........Kg8 (only flight sq.
22.Qxe6# Nothing in the right place to help.

That's it, no other better choice.

Feb-15-16  stst: <However, I didn't calculate all the way to mate after 22...Kh5 >

No need, only a machine will continue, without the Q, continuing the game is wasting everybody's time!!

<Took longer than usual to find the solution for this Monday POTD, because the move is not a usual queen/rook sac.>

Well... may not even be a sac, sometimes it adds other flavor ... to have some freshness!! But, in this case, CG loves to give another sac, just not a Q, nor a R.

Feb-15-16  stst: <In proximity to the enemy Horse, Watch out for the filthy Forks! >

Yes Sir! That's the privilege of a N, none of Q, R, nor B.... even though any of these is usually ranked higher than a N !!

Feb-15-16  saturn2: Bh6 and Black is lost after Kxh6 or Kg8.
Two pieces against the queen is not always hopeless, here however it is.
Feb-15-16  morfishine: <21.Bh6+> is fatal since (1) 21...Kxh6 22.Nf7+ forks the Queen & (2) 21...Kg8 22.Qxe6 mate

*****

Feb-15-16  Cheapo by the Dozen: Suppose nobody told you this was a puzzle.

Then the first thing you'd look at is probably Qxe6, hoping for Qf7# as a follow-on. That move order doesn't work well. From there you'd quickly get to Bh6+ -- and that turns out to work very well.

What's surprising is that, strictly speaking, Qf7# isn't part of the win.

Feb-15-16  Oxspawn: < stst without the Q, continuing the game is wasting everybody's time!!> You have never played me have you? I saw the royal fork, and then thought, I wonder if I could still mess it up with white? Answer: Yes, even on a Monday.
Feb-15-16  gars: May the Good Lord bless all the Mondays!
Feb-15-16  CHESSTTCAMPS: White, a pawn down, has a powerful duo Q+N attacking light square weaknesses at a6, e6 and f7. Black threatens 21... Qd5+, forcing a queen swap that would sharply reduce pressure and would appear to leave black with a winning endgame. White can put a quick stop to this nonsense:

21.Bh6+! Kxh6 (Kg8 22.Qxe6#) 22.Nf7+ Kg7 23.Nxd8 Rhxd8 24.Rxa6 and the material advantage plus the multiple threats (Rxa8, Qxa8, Qxe6 and Qxb5) are overwhelming.

Feb-15-16  whiteshark: <21.Bh6+>, and that's it.
Feb-15-16  YetAnotherAmateur: 21. Bh6+ wins, with either:

A) 21. ... Kxh6 22. Nf7+ Kmoves 23. Nxd8

B) 21. ... Kg8? 22. Qxf6#

Feb-15-16  LoveThatJoker: 21. Bh6+ Kxh6 (21...Kg8 22. Qxe6#) 22. Nf7+

  gawain: 21 Bh6 gives Black a horrible choice. Take the bishop and allow a royal knight fork or else escape to g8 and be mated. The mate is a nifty one. Black has six pieces in the vicinity--but none of them can help.

Feb-15-16  zb2cr: 21. Bh6+ does it.

If 21. ... Kg8; 22. Qxe6#.

If 21. ... Kxh6; 22. Nf7+ forking King and Queen.

Feb-15-16  Once: Given the escapades of recent POTDs, it's almost an anticlimax that there is a solution.

Examine every check and capture, they say. I wonder what this button does. Oooh, that's exciting!

Feb-15-16  TheFocus: easy peasy. Why not? It's Monday.

Bh6+ wins.

Feb-15-16  dark.horse: Loose K position + an enemy horse on the doorstep can't be good for Black.
Feb-15-16  DarthStapler: Got it easily

  Bubo bubo: 21.Bh6+ Kxh6 22.Nf7+ wins the queen for two minor pieces; Black cannot afford to decline the sac with 21...Kg8 because of 22.Qxe6#
Feb-15-16  King.Arthur.Brazil: Monday puzz is easy! 22.Bh6+ Kxh6, 23.Nf7+ win the Black Q or 22.. kg8 23.Qxe6#. Good combination! I guess would be better to start after 16... cxb5 17.?
