| Dec-22-15 | | CliftonJ: I thought of
16. Bh7+ Kh8
17. Bg8
Only 17. ... g6 prevents immediate mate, but after 18. Qxg6, it's over. |
|
| Dec-22-15 | | gofer: I looked at Bh7+ for far too long as I realised that Bf5 put a spanner in the works, but after managing to finally disregard that, the rest was easy! For those with time to kill and in the festive mood. If found this Christmas Tree game a couple of years ago at NoradSanta, but they don't have it there anymore... But I found it somewhere else... ...be warned, its a little addictive... http://www.primarygames.com/holiday... |

 | | Phony Benoni: <CliftonJ> 16.Bh7+ Kh8 17.Bg8 Qxg8! <jith1207> You may be on to something here. Of course, after <16.Ra1 Qxa1> [forced; the queen is trapped] <17.Qc4+ Kh8 18.Nf7+> 
click for larger view18...Kg8 walks into the standard smothered mate, as the White' ♗e4 covers h7. So Black would have to go in for <18...Rxf7 19.Qxf7>. Black is actually a piece ahead, but I don't know if he can defend against White's threats. But I've already talked too much tonight, so let somebody else figure it out. |
|
| Dec-22-15 | | moodini: It seems that certain Englishmen think alike. Too much port and stilton the night before? I also saw Ra1 winning the queen for a piece or forcing mate after Qxa1 Bh7+ and Bg8. It wins, but why not just mate in two? Ah no, it loses, Phony Benoni killed our line!
Back to the port it is then. |

| Dec-22-15 | | patzer2: Took me a while to find today's 16. Bd5+! solution because, starting with 16. Bh7+?!, I was trying too hard to exploit the potential for trapping Black's Queen or Rook. After finding those possibilities didn't work, and knowing this is supposed to be an "easy Tuesday," I finally realized if I could get my Bishop out of the way I could mate on h2 with the Queen. However I still made it hard on myself because I first looked at 16. Bh7+ Kh8 17. Bg8 but 17...Bf5 spoiled the party. After practically all else failed, I finally hit upon the idea of 16. Bd5+! which combines the clearance, decoy, double attack (Bishop Fork) and mate threat tactics in one simple but, at least for me today, not so obvious move. |

| Dec-22-15 | | Willem Wallekers: I love Tuesdays. |

| Dec-22-15 | | patzer2: Deep Fritz 14 indicates Black's decisive mistake was 10...exd5?, allowing 11. Nxd5!  (+1.78 @ 20 depth) which threatens 11...cxd5 12. Qxc8+ .Instead, 10...Nxc3 would have kept Black in the game as Deep Fritz 14 indicates play might continue 11. Bg5 Qc7 12. Qxc3 cxd5 13. Qxc7 Bxc7 14. Rfc1 Kd7 15. b4 a6  (=0.59 @ 22 depth). Early in the opening, 7...b6?!, which is the only move in the OE data base with this try, looks suspect. Better IMO is active development with the popular move 7...0-0 = as in Onischuk vs Radjabov, 2015. |

I tried that first too... but it's 17...QxBg8 that really spoils the party, 17...Bf5 is complicated
i.e. 17. Bg8 Bf5 18. Qxf5, if RxQf5, then 19.BxQa2 and White is still in business.

| Dec-22-15 | | whiteshark: I wonder if black didn't see the # coming? |
|
| Dec-22-15 | | Sniffles: It's similar to the old saying, 'You're foot will never get well as long as the horse is standing on it'. = Your checkmate won't happen until you send that bishop off to commit suicide. |

| Dec-22-15 | | Sularus: I'm with the Bh7+ then Bg8 group on this one. |
|
| Dec-22-15 | | patzer2: <jith1207: Would not the line for 16.Ra1 be: 16..Qxa1 17. Qc4+ ...> Deep Fritz 14 gives the win 16. Ra1 Qxa1 17. Bd5+! Rf7 18. Qg6 Be6 19. Bxe6 hxg5 20. Qxf7+ Kh7 21. Qh5#. |
|
| Dec-22-15 | | zb2cr: The Bishop needs to step out of the Queen's way with gain of tempo. Fortunately, such a move is available with 16. Bd5+. No matter whether Black captures the Bishop with Queen or Pawn, or plays 16. ... Kh8 to get out of check, 17. Qh7# follows. Easier than yesterday's puzzle. Now, why don't such lines come up in my games? |
|
| Dec-22-15 | | jith1207: <Phony Benoni>: Thnak you, That's exactly the line I was looking at and if Rxf7, I see a quick mate as well. I don't see any good defenses for Black to escape the inevitable as far as I could see. There are no checks available for Black even to force something different,and first of all, White seems to have a forcing line in hand till mate. I will look into this later if I don't see anyone updating about this line here. |
|
| Dec-22-15 | | jith1207: Thank you <patzer2>, I love that line too. But for some reason, I was going for smothered & discovered mate / checks, as the sadist in me seems to prefer that when available. |
|
| Dec-22-15 | | dfcx: most people assume this is a mate in 2, however black can delay mate with 16.Bd5+ Rf7 17.Bxa2 Nd7 (hxg5 18.Qg3 mates sooner) 18. Qh7+ Kf8 19. Nxf7 wins both queen and rook for white. |
|
| Dec-22-15 | | thegoodanarchist: I got Sunday but missed Tuesday? Oh, man, Christmas is ruined... I saw 16.Bh7+ Kh8 17.Bg8? will set up Qh7, and the two protectors of the queen, the knight and bishop, cannot be captured in 1 move. But of course, the Black queen can play 17...Qxg8 and now the h7 mate is thwarted. I rushed it and didn't check Black's replies, and now Christmas is ruined. Actually, though, I will just count Kwanzaa as ruined and Christmas is still going to be great. I don't celebrate Kwanzaa anyhow, I don't like any holiday that needs two vowels to make the same sound as only one of those vowels can make. |
|
| Dec-22-15 | | kevin86: White has a mate, if only he could get that darn bishop out of the way. So what's a better move than to use that bishop to attack the black queen. Black's grim choice: either lose the queen or be mated 9probably mated anyway) |
|
| Dec-22-15 | | AvidChessMan: My thought process for this puzzle: move the e4 bishop out of the way to open up the mating diagonal for the white queen - to a spot the causes the most trouble for black. D5 looks pretty good to me! |
|
| Dec-22-15 | | stst: <thought that the black pawn -- rather than the queen -- would capture the bishop.> Really doesn't matter, the point of Bd5+ is to make way/room for Qh7# The only delay is to raise the R: Rf7, but then immediately BxQ and as said, the R is till pinned! |
|
| Dec-22-15 | | stst: <I'm with the Bh7+ ...> Sometimes, actually often, chess is a beauty contest... In this case, thought that the majority will vote for Bd5+ to harass the Q as well as making way for Qh7# is far more beautiful!?! (the ? maybe superfluous!!) |
|
| Dec-22-15 | | stst: <...too stupid ..>
I was "trained" not to use that word in any occasion. "lazy" maybe better?! (not advocating it either!!) |
|
| Dec-22-15 | | stst: < Deep Fritz 14 gives the win 16. Ra1 Qxa1 17. Bd5+! Rf7 18. Qg6 Be6 19. Bxe6 hxg5 20. Qxf7+ Kh7 21. Qh5#.> These machines are too expensive for me, but good to learn, quite a sequence to win. BUT, that's excatly the difference between engines and humans ==> the asethetic factor! Still think 16.Bd5+ is more beutiful, even though the Rf7 may lead to a longer winning sequence. |
