|Feb-21-12|| ||Kinghunt: After 7. e5 Bc7 8. Bxh7+ Kxh7 9. Ng5+ Kg6 (the only move offering any defensive chances), I would want to play 10. h4, threatening 11. h5+ and 12. Nxe6+. As far as I can see, there's no defense short of simply playing 10...Qe8 to not need to lose the queen. But that still loses to 11. h5+ Kh6 12. Nxe6+ Kh7 13. Nxc7 and white will be at least a rook up. I think this may be a bit cleaner than Pillsbury's solution.|
|Feb-21-12|| ||rilkefan: I only calculated to 11.Qg3, before checking that it wasn't Wednesday night or later.|
<newzild>, I'm looking at 9... Kg8 10. Qh5 Re8 11. Qh7+ Kf8 12. Qh8+ Ng8 13. Nh7+ Ke7 14. Bg5+ in your line and not seeing black surviving.

I think White needs to take a different tack than usual and avoid 11.Qxf7+, which eventually frees up the f7-square for Black's king. Instead, <11.Qh7+ Kf8 12.Qh8+ Ng8 13.Nh7+ Ke7>
click for larger view
And now <14.Bg5+>. 14...f6 allows 15.Qxg7#, so Black must return the piece with <14...Nf6>. I like 15.Qxg7 at that point, getting the queen out of attack and winning a second pawn before recapturing the knight. White's attack looks overpowering, even if not immediately fatal.
|Feb-21-12|| ||rilkefan: And <Kinghunt> pawns Pillsbury.|
|Feb-21-12|| ||sevenseaman: Still all on board. I am no expert on opening theory but Black's development looks a bit funny to me.|
First off I feel like advancing e4 to e5.
7. e5 dxc4 8. Bc2 Bc7 9. Ng5 are my thoughts. 'Easy' could well mean some other tactical trick but this looks simple enough.
Black has choices at 7;
Bc7(see my line), Bb4 (Qc2) or dxc4 (Bc2 or even Bxh7+). I'll go with the most sensible looking < 7...Bc7>.
<7. e5 Bc7 8. Bxh7> (retains tempo) <8...Kxh7 9. Ng5+ Kg6> (better than Kg8) <10. Qg4 f5>
(and decision time; e.p. or let it be? Let it be and keep the enemy forces unmobilized; Q and the f8R.)
<11. Qg3> (not 11. Qf4 keeping N lift in hand till Black commits himself to Qd7 or Rh8)
<11...Qd7 12. Qh4> 1-0 with mate from h7 staring, with only a spite move for reaction.
I expect plenty of debate today. I wonder if NNs were kept? (You know what I mean)?
It looks a tough week ahead.
Parting shot: A man crazy for planning had this slogan painted on a board hung on his office door;
'Always plan ahe-
I wish I could make it look like a board which finished and did not take 'ahead' in the same line.
|Feb-21-12|| ||scormus: <'Always plan ahe-
Right, that's exactly the lesson I need to learn!
|Feb-21-12|| ||gprice: < sambo: <12... f4 13.Qh7+ Kxg5 14.h4+ Kg4 15.f3+ Kg3 16.Ne2# and even white king helps to checkmate.>
Actually, black still has a move after this, so it isn't checkmate; but after 16...Kxg2 17. Rg1+ Kh2 18. Bxhf4+ Rxf4 19. Qxg7, black is finally toast.>
Actually just 15. Qxg7+ and mate next:
15... Ng6 16. Qg6#
15... Kh5 16. Qg5#
|Feb-21-12|| ||NewLine: WOW! 12 ply non-forced variation (and infinite number of side-lines). Unless your brain's made of silicon (or carlson), I don't think you'd call that "Easy".|
|Feb-21-12|| ||Limpin Kt: Tricky puzzle. The attack here, i rather think is instinctive and it is also correct, but black is not all lost as i thought in my first post. The absence of protective knight at f6 the knight being misplaced at e7 seriously compromises black's defences. 1.e5 Bb4 2.Bh7 Kh7 3.Ng5. Now
3... Kg6!? 4.h4! Qa5 5.Qd3 f5 6.h5 kh6 7.Ne6 kh7 8.Nf8 kg8 9.Ng6 and black has no hopes. But 3.... Kg8 4.Qh5 Re8 5.Qh7 kf8 6.Qh8 in this line <phonybenoni> seems to be correct, white wins the piece back and captures a pawn and has a powerful attack but the position is unclear. I'm stil working on it.|
|Feb-21-12|| ||gofer: This seems a little "hard" for a Tuesday, but still only took a couple of seconds.|
<7 e5 Bb4>
<8 Bxh7+ Kxh7>
<9 Ng5+ Kg8>
<10 Qh3> mating
The problem for me is that neither Kxh7 nor Kg8 is forced. There are other options for black
and none are as bad as those given above.
Time to check...
Okay black didn't play Kg8 and played the better Kg6, but still should have tried to survive a little longer by playing 10 ... Nf5, which loses the queen but avoids mate for at least a while!
Obviously, the real question is whether <8 ... Kh8> survives much
longer, but that is way above a Tuesday level puzzle and work is calling...
|Feb-21-12|| ||RookFile: Just another very interesting Pillsbury game. Haven't seen a boring one yet from him.|
|Feb-21-12|| ||Once: C-3PO: Sir, the possibility of successfully navigating an asteroid field is approximately 3,720 to 1.|
Han Solo: Never tell me the odds.
Continuing our star wars theme, today we have a classic choice - are you C3-PO or Han Solo?
On the face of it, that doesn't sound like the hardest decision you have ever been asked to make. On the one hand we have a mincing cowardly robot, and on the other we have Indiana Jones, the president of the Yooonited States and John Book all rolled into one.
But these two actually represent a difference of approach. C3-PO needs to calculate the percentages, assess every line, know everything that is knowable. So in today's position, we need to know what would have happened if black didn't play 7...Bc7 and tried something like 7...Bb4 instead.
And Herr Fritz (second cousin to C3PO) points out that 10. Ne2 or 10. h4 would have been stronger than 10. Qg4, because of the messy line 10. Qg4 f5 11. Qg3 f4. Sure, white is still winning, but it's not silicon precise.
And then we have the other king retreat with 9...Kg8. Are we certain that we can winkle him out? We play Qh5 and Qxf7+ but then we need to bring some more pieces into the attack. The trouble is that both black and white have a lot of choices.
But then who wants to play like a robot? C3PO spends at least a part of every star wars film disassembled - he is naked for the whole of episode 1 and his memory is wiped for the duration of episodes 4, 5 and 6 which is probably a blessing as he doesn't remember the awful acting of 1, 2 and 3.
Or there's Han Solo. He doesn't calculate. He doesn't want to know the odds. He doesn't even believe in the force. All he needs is a good blaster on his hip and a wookie by his side. Mind you, is he going to be mightily upset in the (as yet unfilmed) episode seven when he learns that the emporer was his father...
In Han Solo mode, all we need to know is that e5-Bxh7+ has just gotta be the right way to go. We are running through death star corridors waving our blaster at the stormtroopers. We are zapping Darth Vader's tie fighter in the falcon. We don't know the odds, we don't need to know the odds and we haven't even told our momma when we are going to be home for supper.
But it sure as hell looks like fun.
And let's not forget that the Jedi also believe in trusting your judgement, believing that the Force will guide them. Let's give the last word to Qui-Gon on the eve of the pod race...
Amidala(as Padme): "You Jedi are far too reckless. The Queen is not-"
Qui-Gon: "The Queen trusts my judgement, young handmaiden. You should too."
Amidala: "You assume too much."
|Feb-21-12|| ||SamAtoms1980: I followed moves 7-10 but then diverged with 11.exf6 e.p., can I still say that I got this?|
|Feb-21-12|| ||sevenseaman: Kinghunts>'s idea of 10. h4 is a powerful one. Seems to win in all situations.|
I tried an essay against Crafty. It gives up its DSB first off taking e5. I tried only once but did not not succeed. I forgot Crafty does not recognize castling that I planned for. Here is the link. Crafty is moody and a bit erratic at times.
|Feb-21-12|| ||lost in space: After solving today's puzzle I was asking myself why to play 7.e5. Isn't 7. exd5 as good?|
7. exd5 exd5! (not cxd5)
8. Bxh7+ Kxh7 9. Ng5+ Kg8! 10. Qh5 with mate threat on h7
10...Bf5! and it is Black who is winning.

|Feb-21-12|| ||RookFile: Regarding Han Solo, what choice did the guy have? If he doesn't go to the asteriod field, he'd dead. Better to have a slim chance than none at all.|
|Feb-21-12|| ||morfishine: <7.e5> poses a double-problem for Black: His DSB is attacked while the devastating <8.Bxh7+> is looming.|
From a pure chess standpoint, Black must let the Bishop go and play <7...g6>. After all, the security of one's own King takes precedence over a mere Bishop.
Will it save the game? No
But at least the Black King will have a chance to prepare his will. :)
|Feb-21-12|| ||Memethecat: I've always like it when my opponent puts his KS N somewhere other than f6, but its just hit home, really hit home, what an important role it plays in defense, as well as being well placed to enter the fray.|
<7e5 Bc7 8Bxh7+ Kxh7 9Ng5+ Kg8 10Qh5>mate next.
<7e5 Bc7 8Bxh7+ Kh8 9Ng5 f6 10Qh5 fxg5 11Bg6+>mate next.
<7e5 Bc7 8Bxh7+ Kxh7 9Ng5+ Kg6 10h4 Nf5 11h5+ Kh6 12Nxf7+> wins the Q at the very least.
Missed the Qg4 line, but I'm still happy with my effort.
|Feb-21-12|| ||gofer: <<Phony Benoni> <newzild> In your line after <7.e5 Bb4 8.Bxh7+ Kxh7 9.Ng5+ Kg8 10.Qh5 Re8>:>|
Why not play
<11 Qxf7+ Kh8>
<12 g4 ...>

This releases Rh1 to come to the attack via g1, g3 and h3, but more importantly stops
black's only good defensive move Nf5!
I see no good moves for black.
12 ... Rf8 13 Qh5+ mating
12 ... Rg8 13 Qh5#
12 ... Ng6 13 Qxg6 Kg8 14 Qh7+ Kf8 15 Qh8+ Ke7 16 Qxg7#
12 ... Nd7 13 Nxd6 winning the queen
12 ... Ng8 13 Qg6 winning the queen
Crafty comes unstuck very quickly
<12 ... Qd7>
<13 Rg1 dxc4>
<14 Rg3 Nf5>
<15 Rh3+ Nh6>
<16 Qg6 Kg8>
<17 Rxh6 Kf8>
<18 Rh7!! ...>
The black king is stuck as any defense leads to a quick
mate. So all black can do is look for other moves that do
not involve his King, Queen or Rook!
All white has to do is push the f pawn to complete the attack!
|Feb-21-12|| ||OhioChessFan: Seems more like an attack you'd find in a French, not a Semi-Slav, with the Bxh7 sac after Black castles into the attack. I was with the 10. h4 crowd, though the odd looking 10. Ne2 is also strong.|
|Feb-21-12|| ||Once: <RookFile> My friend, there are always choices...|
Instead of venturing into the asteriod field, he could have allowed the Millennium Falcon to be tractor-beamed into the other ship's hold. Meanwhile everybody hides in secret compartments hidden under the floorboards until the coast is clear. Always assuming that the empire doesn't have any scanners that can detect life signs.
Then he entices two storm troopers into the falcon, beats them up and steals their clothes.
Then he sneaks around the other ship until he finds a way to turn the tractor beam off.
Then he sneaks back on board the falcon using nothing more futuristic than the old ploy of wearing the enemy's uniform.
Then blast off out of the other ship's hold whlist not being shot to bits by the laser gun turrety things which he had not been able to turn off cos they're on a different circuit board to the tractor beam.
On second thoughts, nah, you're right. That's too far-fetched even for star wars.

|Feb-21-12|| ||zb2cr: 7. e5 opens the diagonal for the White Bishop to h7. Black can play 7. ... Bb4 or 7. ... Bc7. Neither does anything to prevent White from playing 8. Bxh7+, Kxh7; 9. Ng5+ with a winning attack.|
|Feb-21-12|| ||agb2002: The material is even.
White can start a quick attack against the black castle with 7.e5:
A) 7... Bb4 8.Bxh7+ Kxh7 (else lose a pawn and White still has an attack: 8... Kh8 9.Ng5 g6 10.Qg4 and 11.Qh4) 9.Ng5+
A.1) 9... Kh8 10.Qh5+ Kg8 11.Qh7#.
A.2) 9... Kh6 10.Nxe6+ and 11.Nxd8 + - [Q+2P vs B+N].
A.3) 9... Kg8 10.Qh5 Re8 11.Qh7+ (11.Qxf7+ allows the black king to escape to f7) 11... Kf8 12.Qh8+ Ng8 13.Nh7+ Ke7 14.Bg5+ Nf6 (14... f6 15.Qxg7#; 14... Kd7 15.Bxd8) 15.exf6+
A.3.a) 15... gxf6 16.Qxf6+ Kd7 (16... Kd6 17.Qe5+ and 18.Bxd8) 17.Qxf7+ Be7 18.Nf6+ + - [N+2P vs B].
A.3.b) 15... Kd7 16.Qxg7 + - [N+2P vs B].
A.4) 9... Kg6 10.h4
A.4.a) 10... Rh8 11.h5+ Rxh5 (11... Kh6 12.Nxf7+; 11... Kf5 12.Qf3#) 12.Qxh5+ Kf5 13.Qf3+ Kg6 14.Qxf7#.
A.4.b) 10... Qc(d)7 11.h5+ Kh6 12.Nxe6+ g5 (12... Kh7 13.Nxf8+ and 14.Nxd7) 13.hxg6+ Kxg6 14.Qg4#.
A.4.c) 10... Qe8 11.Qg4
A.4.c.i) 11... f5 12.h5+ Kh6 13.Nxe6+ and mate in two.
A.4.c.ii) 11... f6 12.h5+ Kh6 13.Nxe6+ g5 13.hxg6#.
A.4.c.iii) 11... Nf5 12.h5+ Kh6 13.Ne4+ Kh7 14.h6 g6 15.Nf6+ and 16.Nxe8 + -.
B) 7... Bc7 8.Bxh7+ is similar to A, except that 15.Qxg7 looks stronger instead of 15.exf6+ in A.3.
|Feb-21-12|| ||Memethecat: <newzild 9...Kg8 10. Qh5 Re8> |
11Qxf7+ Kh8 12h4 Nf5 13Qh5+ Kg8 14Qh7+ Kg8 15Qg6 Qd7 16Nh7+ Ke7 17Bg5#
(16...Kg8 17Nf6+) forks K & Q
This works, but I could be missing something. Its definitely a puzzle with more than 1 right answer.
