|Jun-05-12|| ||Patriot: This looks like a classic bishop sacrifice.
11.Bxh7+ Kxh7 12.Qh5+ Kg8 13.Ng5 Re8 14.Qxf7+ Kh8 15.Qh5+ Kg8 16.Qh7+ Kf8 17.Qh8+ Ke7 18.Qxg7#.
Black could throw in 13...Bxf2+ 14.Kd1 and black is still lost. He can also sac the queen with 13...Qxg5 but that's just losing.
|Jun-05-12|| ||Lambda: I was thinking too rigidly of the classic bishop sacrifice, so my second move was Ng5+ and I was trying to find complicated lines after ...Kh6. (I think it still wins, 11.Bxh7+ Kxh7 12. Ng5+? Kh6 13. Qh4+ Kg6 14. Qh7+ Kxg5 15. Qxg7+! cutting off an escape route f4-e5-d6 and white can chase the black king towards white's own pawns, but there's too much to calculate precisely.) If I'd never seen a bishop sacrifice at h7 before, I'd probably work it out easily, but as it is, 12. Qh5+ fell in a blind spot.|
|Jun-05-12|| ||desiobu: Qxf7+ first is the key.|
|Jun-05-12|| ||VincentL: "Easy".
11. Bxh7+ Kxh7 12. Qh5+ Kg8 13. Ng5 Re8 14. Qxh7+ Kf8 15. Qh8+ Ke7 16.
Qxg7 with Qf6# to follow.
Black can give up Q for N with 13......Qxg5.
If black declines the original sacrifica and plays 11.....Kh8 mate will follow after 12. Qh5 and Bg6+
|Jun-05-12|| ||TimothyLucasJaeger: The greek gift 11 Bxh7+ cannot be accepted, since after 11 ... Kxh7, the forcing sequence 12 Qh5+ Kg8 13 Ng5 Re8 (13 ... Bxf2 doesn't help. White should avoid 14 Kxf2 Qb6+ which would allow black's king access to d8 and simply play 14 Kf1) 14 Qxf7+ Kh8 15 Qh5+ Kg8 16 Qh7+ Kf8 17 Qh8+ Ke8 18 Qxg7 is checkmate.|
But after 11 ... Kh8 12 Qh5 Re8 13 Bg6+ (the tempitng 13 Ng5 can be met with 13 ... Nxe5) Kf8 14 Bxf7 white is up two pawns and black's king is exposed.
|Jun-05-12|| ||JohnTal: Duhm Duhm Duhm Duhm DUMB! If this game become a GOTD, this is the pun!|
|Jun-05-12|| ||TimothyLucasJaeger: Looks like i let the black king jump from h8 to f8 in one of my variations. Sorry for any confusion i may have caused.|
|Jun-05-12|| ||Jesspatrick: I've seen this combination on a tactics training problem set.|
|Jun-05-12|| ||kevin86: This problem is part of :Chess Combinations 101-a freshman chess class.|
White gives up bishop to mate with queen and knight. Black's pieces don't help,they just get in the way.
|Jun-05-12|| ||scormus: <sevenseaman> thanks for your flattering comments! Well, I notice many posts look closely at happened earlier that resulted in the puzzle position. Occasionally I try to do the same, like today.|
Thanks for your suggestion - yes, opening redy reckoner for key themes and pitfalls would be an interesting idea, not sure how easy it would be, I think not easy to compile something reliable. I suspect anyone who could do that would be able to make serious money from the game.
However, I'll post on your forum if I have any constructive thoughts.
|Jun-05-12|| ||BOSTER: This is the position after move 8.dxc5 where black play...Nd7 (instead Bxc5).|

The idea not only to attack both black pawns c5 and e5, but what is really most important that after Nxc5 or Nxe5 white bishop d3 has to leave b1-h7 diagonal .
If 9.Qg4 Nxe5 10.Qxg7 Nxd3+ 11.cxd3 Bf6 and black is better.
The idea to exchange the bishop for knight move 5.Bxf6 Bxf6 is very attractive. If I am not wrong, Gulko used the same idea playing against Karpov.
|Jun-05-12|| ||chrisowen: Switching time for flanks yes the dig in dip us h7+ in uncovering blacks defences proved unworthy in dearth of issues in good healthy flood it them in h5 g5 xtra transfer i know main course comes later might Max the spooler have the smoother finish a climbing king whoops heavers a der dummy account levels off ten c6 calculational misrep one.|
|Jun-05-12|| ||drnooo: hey gumbach: Pesta non control,
|Jun-05-12|| ||dzechiel: White to move (11?). Material even. "Easy."
Well, there's "Easy" and there's "Easy".
The bishop sacrifice on h7 is text book, but envisioning the whole combination takes some imagination.
It goes something like...
11 Bxh7+ Kxh7
On 11...Kh8 12 Qh5 ends this quickly.
12 Qh5+ Kg8 13 Ng5
Threatening 14 Qh7#.
This, and 13...Qxg5, are the only moves that prolong the game.
White needs to remove the f-pawn first.
14...Kh8 15 Qh5+ Kg8 16 Qh7+ Kf8 17 Qh8+ Ke7 18 Qxg7#
I've seen easier Thursday positions.
Time to check.
|Jun-05-12|| ||shalgo: It goes to show how much of chess is pattern recognition. I have very poor visualization skills, but saw the whole line to move 18 in less than 30 seconds, because I have studied the Greek Gift sacrifice, and this line is one of the most fundamental bases for that sacrifice.|
|Jun-05-12|| ||Ghuzultyy: Pawn on e5, Knight eyeing g5, Bishop eyeing h7, the queen is close to kingside. A famous pattern.|
<11.Bxh7+ Kxh7 12.Qh5+!>
12.Ng5+? Kh6 would make things harder for white.
<12...Kg8 13.Ng5 Re8>
When you see Re8, you should know that you are winning without calculation here. The trick is pretty easy and works as long as you have that e5 pawn.
<13.Qxf7+! Kh8 14.Qh5+ Kg8 15.Qh7+ Kf8 16.Qh8+ Ke7 17.Qxg7#>
|Jun-05-12|| ||LoveThatJoker: Tuesday, June 5th, 2012
<11. Bxh7+ Kxh7>
(11...Kh8 12. Qh5 mating)
<12. Qh5+ Kg8 13. Ng5 Qxg5>
(13...Re8 14. Qxf7+ Kh8 15. Qh5+ Kg8 16. Qh7+ Kf8 17. Qh8+ Ke7 18. Qxg7#)
|Jun-05-12|| ||agb2002: <zb2cr> Thank you!|
|Jun-05-12|| ||bischopper: the classical mate: attack with bischop h7+ check and this game is finished.|
|Jun-05-12|| ||BlackSheep: "Beware of Trojans they're complete smegheads"|
|Jun-05-12|| ||e4 resigns: Here is a similar game, a bit quicker.
All in all, just silly on black's part.
Greco vs NN, 1620
|Jun-05-12|| ||TheBish: M Pestalozzi vs D Duhm, 1900|
White to play (11.?) "Easy"
This is the standard bishop sacrifice (also known as the "Greek gift") arising from the French Defense, when Black castles prematurely.
11. Bxh7+! Kxh7
Darned if you do, darned if you don't... capture the bishop, that is! If 11...Kh8 12. Qh5 and Black will have to give up major material with 12...Re8 13. Bg6+ Kg8 14. Bxf7+ Kf8 15. Bxe8.
12. Qh5+ Kg8 13. Ng5 Re8
Black gets mated after this, but the alternative wouldn't be much fun to play: 13...Qxg5 14. Qxg5 and the attack would rage on, ahead a queen and pawn for two minor pieces.
14. Qxf7+! Kh8 15. Qh5+ Kg8 16. Qh7+ Kf8 17. Qh8+ Ke7 18. Qxg7#.
|Jun-05-12|| ||stst: Only one way to initiate a check-series:
13.Ng5 and no defense to Qh7#
12.Qh5 and no defense to Bg6 dis+ #
|Jun-06-12|| ||cjgone: Took me a very long time to notice the mate.|
|Jun-06-12|| ||dragon player: 11.Bxh7+ is tempting, but this pattern has been used as a spoiler before.
However, I don't see any problems, so why not:
If 11...Kh8 12.Qh5, threathening 13.Bg6+ and 14.Qh7#
Time to check.
Exactly the same.
