| Feb-02-12 | | KingV93: ah ha! ♗f7! very sneaky back door assassin type move. brilliant. missed it. |
|

 | | piltdown man: Saw it all, except the last brilliant move. |
|
| Feb-02-12 | | Memethecat: My 1st line <18Rxf6 Rxf6 19Bxf6 Qc7> wins a piece but I wondered if there was anything better, it came in a flash <18Rxf6 Rxf6 19Bxh6> & black would be unable to stop the discovered mate <20Bg5# or 20Bf4#> I punched the key with total confidence. There's blind spots & there's BLIND SPOTS, how did I miss <19...gxh6>? |
|
| Feb-02-12 | | sevenseaman: One wishes the white Rs were doubled on the 'f' file for a walk in the park. Still White wins by repeated hammering of f6. He is one hit short but the LSB is nicely placed for a timely jump into the fray. He must start with the R.
<18. Rxf6 Rxf6 19. Bxf6 gxf6 20. Qxf6 Qc7 21. Bf7> 1-0 1 |
|
| Feb-02-12 | | Memethecat: In fact <19...Qf2> is the shot that really scuppers my disasterous <19Bxh6>. Pixie lyrics "where is my mind" are lodged in my scull on auto-repeat. |
|
| Feb-02-12 | | Oxnard: 18. Rxf6! Rxf6 (18. ... gxf6 19. Qxh6#) 19. Bxf6 gxf6 20. Qxf6. Now to defend against Qf7+ Kh8 Qg8# it seems black only has 20. ... Qc7. But now, 21. Bf7, and it seems the only defense black has against mate is to sacrifice his queen. |

 | | OhioChessFan: One of my worst efforts on a Thursday. Completely missed 21. Bf7 so I discarded that line and gave up. |
|
| Feb-02-12 | | Patriot: Material is even.
I looked at several candidates:
18.Qxh6+ gxh6 and 19.Bg8+, 19.Rxf6 Rxf6 20.Bxf6, or 19.Bxf6 look to be losing. 18.Bxf6 Rxf6 19.Rxf6 gxf6 20.Qxf6 is interesting.
18.Bxh6 gxh6 19.Rxf6 looks similar to above but 19...Be7 looks complicated. 18.Rxf6 Rxf6 19.Bxh6 gxh6 20.Qxf6 is nice. Another twist is 18...Be7. This is too complex for me this morning and a lot of permutations. I've run out of time. |

| Feb-02-12 | | LoveThatJoker: Alright. So this puzzle looks pretty straightforward, although the position has a cleverness about it which is instructive. I'm liking 18. Rxf6! (much better than 18. Bxf6? gxf6 19. Rxf6 Bd7 where White wins a pawn, but Black extricates himself from the positional bind) 18...Rxf6 (18...gxf6 19. Qxh6#) 19. Bxf6 gxf6 20. Qxf6 Position after 20. Qxf6
(Black's LSB is completely paralyzed!)
click for larger view20...Qc7 21. Rf1 Rb8 (21...b6 22. Qh4  ; 21...h6 22. Qg5 ; 21...Qg7 22. Qd8 Be7 23. Qe8! ) 22. Qh4! Kg7 (22...g5 23. Qh5) 23. Rf7+ Qxf7 24. Bxf7 Kxf7 25. Qxh6 wins LTJ
PS. I decided to include a diagram today so as to emphasize the plight of Black's LSB. Of course, I had to write it out by hand (piece by piece, line by line). But I hope it helps anyone who reads my post for today to see the predicament of that piece! |
|
| Feb-02-12 | | srag: I solved it, so this POTD is too easy for a Thursday. |
|
| Feb-02-12 | | LoveThatJoker: Well, I could very well fire up stockfish to see if there is a refutation to 20...Qc7 21. Rf1!?, but I would rather let one of my fellow kibitzers here tell me if there is. This line I've presented seems totally winning so I can give myself the full point today. Any feedback on my line would be much appreciated.
Sincerely,
LTJ |

| Feb-02-12 | | James D Flynn: 18.Rxf6 Rxf6 19.Bxf5 and the bishop cannot be taken because mate follows: g7xf6 19.Qxf6 Qc7 20.Bf7 (threat mate in 2 Qxg6 and then Qxh6 mate) Qd6 21.Bxg6+ Kg8 22.Qf7+ Kh8 23.Qh7+ |
|
| Feb-02-12 | | CHESSTTCAMPS: In this middle-game position, material is even, but white has a lead in development, sounder pawn structure, and strong pressure on the king-side. Black would like to play 18... Bd7, connecting the rooks and protecting the back rank. The h7 pawn is pinned and the g7 pawn is doing double duty, protecting the Nf6 and the h6 pawn. This suggests 18.Rxf6! (much stronger than Bxf6) Rxf6 (gxf6 19.Qxh6#) 19.Bxf6 gxf6 (g5 20.Bxg5 or 19...c5 20.Bxe5 keeps the extra piece) 20.Qxf6 and now the threat of mate in 2 leaves no good option: A) 20... Qc7 21.Bf7 and black must give up the Q to stop 22.Qxg6+ Kh8 23.Qxh6# B) 20... h5 (best) 21.Qf7+ Kh6 22.Rf1! and the threat of Rf6 decides quickly. C) 20... Bd7 21.Qf7+ wins a piece.
D) 20... c5, Bxc3 and others 21.Qf7+ Kh8 22.Qg8#.
Time for review... |
|
| Feb-02-12 | | sopuli: <Sastre> Thanks! I completely missed 22 Bxg6+. |
|
Feb-02-12
 | | Penguincw: Jackpot! As usual, I don't calculate too far (unless it's a checkmate). |
|
| Feb-02-12 | | James D Flynn: Looking at the other posts I see that I missed the important defensive try 19....h5 instead of 19....Qc7. Now 20.Bf7 doesn't work c5 21,Bxg6+ Kh6 and both f8 and f4 are covered by Black so no Q checks. However I think 20.Bg8+ wins Kxg8 21.Qxg6+ Kh8 22.Qe8+ Kg7 23.Rf1 |
|
| Feb-02-12 | | 5hrsolver: The reason why 18.Bxf6 fails is
18.Bxf6 gxf6 19.Rxf6 Be7
pinning the rook |
|
| Feb-02-12 | | reztap: Must be too easy. I solved it right away. |
|
| Feb-02-12 | | David2009: K Treybal vs K Moll, 1907 White 18? Exchange twice on f6 starting with 18.Rxf6 (the most forcing continuation): 18.Rxf6 Rxf6 19.Bxf6 gxf6 20.Qxf6. What have I missed?- time to
check:

OK I didn't analyse furher - I didn't feel the need to.I would have expected Black to develop the Bishop somewhere, but I see it can't be done without losing it, which leaves only 19...h5 losing as pointed out (for example) by <CHESSTTCAMPS>. Come back Crafty EGT all is forgiven - you are sorely missed. |
|
Feb-02-12
 | | LIFE Master AJ: 18.RxN/f6! if pawn takes, then QxP/h6#.
(Don't forget the LSB@b3.)
Looks like 18...RxR/f6▢; 19.BxR/f6, PxB/f6; 20.QxP/f6, and Black is busted. (20...Qc7; 21.Bf7, and now Black might have to give up the Queen to prevent mate.) |
|
Feb-02-12
| | LIFE Master AJ: <David2009> Is the Crafty EGT thing broken? |
|
| Feb-02-12 | | LoveThatJoker: I've confirmed with Stockfish what would happen after 20...Qc7 21. Rf1 and it says that White is winning by at least 4 pawns in all variations! That's certainly a winning solution.

| Feb-02-12 | | jackalope: Thanks <morfishine> for taking a look. As pointed out by you and <CHESSTTCAMP>, White's Rf1 makes Black's game life miserable. After "pushing wood" around, I see that Black can only prolong his agony: <18. Rxf6 Rxf6 19. Bxf6 gxf6 20. Qxf6 h5 21. Rf1! Qc7 22. Qg5 Be6 23. Rf6 Qg7 24. Rxe6 Rf8 25. Kh2> White now enjoys QRBN+p vs qrb and a much better position. 1-0 |
|
Feb-02-12
 | | whittaker: <James D Flynn> I assume you meant 20 ... h5 as a defensive try. White can just play 21 Qxe5 and be two pawns up and continue the K attack with Rf1, etc. |
|
| Feb-02-12 | | kevin86: The final bishop move blocks out the queen and sets the stage for a mate at h6 or g8,with the queen,aided by the bishop. |
