  James D Flynn: I believe there is a mate after 18.Qxd8+ Nxd8 19.Rxd8+ Bf8 20.Rxf8+ Kg7 21.Rf7+ Kh1 22.Bg7+ Kg8 23.Rxe7# or 21…..Kg8 22.Bh6 and the only defense to 23.Rf8# is 22…..Be6 after 23.Bxe6 there is no longer a defense to Rf8#

  Memethecat: 17...Rd8??? Nice way to deal with the Sicilian, not seen it before. Just checked Opening Explorer & there's only 74 games in DB at 4.cxd4, with 73% wins for white.
Apr-16-12  VincentL: "Very Easy".

I see this instantly.

18 Qd8+ mates (almost !)

The full line is 18. Qd8+ Nxd8 19. Rxd8+ .

Now 19.....Ng8 20. Rxg8#

Or 19....Bf8 20. Rxf8+ Kg7 (Ng8 21. Rxg8# as above). 21. Rcxc8+. Now Nxc8 22. Rg8#. So 21....Qc8 (otherwise 22. Rg8#) 22. Nx8 Rxc8 23. Rf7+ Kh8 24. Red7 and white has a material advantage of 2B + N.

This last line is way beyond Monday level.

Let´s see if I missed something easier.

  WinKing: Another queen valiantly sacrifices herself.

18.Qxd8+ Nxd8
19.Rxd8+ Bf8 <(19...Ng8 20.Rxg8#)>

20.Bh6 <(or 20.Rxf8+ or 20.Rcxc8 or 20.Nxa8)>

Choose the flavor you like they all lead to victory.

Apr-16-12  desiobu: Maybe black was frustrated and wanted to take the initiative somehow?
Apr-16-12  Oxspawn: Too easy?
18. Qxd8+ Nxd8
19. Rxd8+ Ng8
20. Rxg8++

Nothing much to think about. Down the road; turn right and carry on until you meet a naked king.

  dzechiel: White to move (18?). Material even. "Very Easy."

So..., it looks like

18 Qxd8+ Nxd8 19 Rxd8+ Bf8

is in order. White can pick up additional material with

20 Rxf8+ Kg7

giving white a rook and two minor pieces for the queen. I don't see a checkmate beyond that, but it might be hiding in there somewhere.

Time to check the kibitzing.

Apr-16-12  Oxspawn: O Good, there is something to think about:
18. Qxd8+ Nxd8
19. Rxd8+ Bf8
gives the King an escape square.

20. Bh6 B(c8)e6
21. Rxf8+ Qxf8
22. Bxf8 Rxf8
23. Bxe6

and white has a rook a bishop and two knights left against a rook and a knight, and is threatening Rc8. Did I get lost there somewhere?

Apr-16-12  hugogomes: White ends up 2 rooks and 2 knights ahead! This could be a friday puzzle to find the best continuation. 20. Rxf8, Kg7 (only move)
21. Rf7+, Kh8 (only move)
22. Bh6!, Be6 (only move)
23. Bg7+, Kg8 (only move)
24. Bxe6, Qd6 (only move)
25. Rxe7+, Qxe6 (only move)
26. Rxe6, Kxg7
27. Rc7+, Kh6
28. Nxa8 and black can now MAYBE think of resigning

  kevin86: Not as easy as usual for a Monday-true,white wins,but it does take a few extra moves.
Apr-16-12  abuzic: <James D Flynn: I believe there is a mate after 18.Qxd8+ Nxd8 19.Rxd8+ Bf8 20.Rxf8+ Kg7 21.Rf7+ Kh1 22.Bg7+ Kg8 23.Rxe7#>

You mean <21...Kh8>, but even then, there must some missing moves in this line because 22.Bg7+ is not possible, and this is the position after <21...Kh8>:

But you are right about mate after
18.Qxd8+ Nxd8
19.Rxd8+ Bf8
20.Rxf8+ Kg7
21.Rf7+ Kh8 <21...Kg8 22.Bh6 Be6 23.Bxe6 Kh8 24.Bg7+ Kg8 25.Rxe7#.>

22.Bh6 Be6
23.Bxe6 Qd6 <(23...Qf8 delays mate one move)>

24.Nxa8 Nc6 <24...Qxe6 25.Rxe7 Qg8 26.Nb6 fxe4 27.Rc8 Qxc8 28.Nxc8 Kh8 29.Nd6 black moves 30.Re8#>

25.Bb3 Qb4
26.Rc7 Qf8 <26...Qe7 27.R1xc6 bxc6 28.Rc8+ Qf8 29.Rxf8#>

27.Bxf8 h5
28.Bd6 fxe4
29.R1xc6 bxc6
30.Bxe5#.

Apr-16-12  stst: Miss yesterday, got Monday..Q-sac again!!
18.QxR+ NxQ
19.RxN+ Ng8
20.RxN# (supported by B)
Apr-16-12  stst: <Mondays? Moi non plus> always some mystery, saw that B-interpose, but Black couldn't defend any longer if W goes Bh6 first.

  SuperPatzer77: White to play and win - see diagram below:


click for larger view

18. Qxd8+! Nxd8, 19. Rxd8+ Bf8, 20. Rxf8+ Kg7, 21. Rf7+ Kh8, 22. Bh6! Be6, 23. Bg7+ Kg8, 24. Bxe6 (with the idea Rxe7#) Qd6 only move, 25. Rxe7+ (discovered check) Qxe6, 26. Rxe6 (White has great material advantage with two knights, one bishop and two rooks)

Apr-16-12  dragon player: It's monday, which means a queen sac:

18.Qxd8+ Nxd8
19.Rxd8+ Bf8
20.Rxf8+ Kg7
21.Rf7+ Kh8
22.Rxe7

Winning a lot of material for the queen, and the c8-bisshop is lost either.

Time to check.

-------------

Indeed right. Maybe there's a mate, but this is winning.

1/1

  gawain: I was certainly too hasty in proclaiming a back rank mate. But Black has to give up too much material to stave off the mate. 17...Rd8 still merits a Yikes!

  StevieB: Easiest puzzle yet.
Apr-16-12  cyclon: 18. Qxd8+ Nxd8 19. Rxd8+ Bf8 ( -Ng8 20. Rxg8X ) 20. Bh6 Bd7/e6 21. Rxf8+ ( this move first ) and White wins just too much material. What day is it today?
Apr-16-12  cyclon: < VincentL: Or 19....Bf8 20. Rxf8+ Kg7 (Ng8 21. Rxg8# as above). 21. Rcxc8+. Now Nxc8 22. Rg8# > 22. -Kf6.

  LIFE Master AJ: 18.Qxd8+. Not much of a POTD, IMO.

  David2009: T Dowden vs W Petch, 1982 White 18?

18. Qxd8+ wins the house. Time to check:

As expected. Rewind to move 17 just before the disaster:

Afeer 17...Nb6 Black can struggle on with 17...fxe4 giving up the exchange with faint counter-chances against f2. Crafty Endgame Trainer link to practice winning by converting the material advantage: http://www.chessvideos.tv/endgame-t... Enjoy finding the win!
