|Jul-27-14|| ||leow: Sorry, I was mistaken|
|Jul-27-14|| ||trnbg: What if White had played 17.Qb3 (instead of 17.Nxe6)? With Qb3 White gains time to retreat his king to h3, and I can't see a forced win for black.|
|Jul-27-14|| ||Once: Too well known to be a puzzle, but a fun thing to play through all the same.|
As to <Phony>'s castling conundrum. Here's how you castle with your king adjacent to an enemy queen...
First you need to choose a board with narrow edges. The thinnest edges that you can find.
Then, in the course of a game, you capture the enemy queen. You place the captured queen behind your king. Not on the board, but on the imaginary equivalent of squares d0, e0, f0 (white) or d9, e9, f9 (black).
You may then castle as normally, either long or short. And there you have it ... castling whilst your king is adjacent to an enemy queen.
Admittedly, said enemy queen is no longer in play, but no-one said anything about that! ;-)
This same technique also works for pawn, rook, bishop or knight, but I haven't yet figured out a way to do it for an enemy king.
|Jul-27-14|| ||THKVL: If 17) Qb3, then black has Rf4+ and it's mate in 1.|
|Jul-27-14|| ||agb2002: Black has the bishop pair and two pawns for a bishop and a knight.|
White threatens 13.Nxd8, 13.Nxh8 and 13.Qxd5.
The position of the white king invites to play 12... 0-0 to create a mating net:
A) 13.Nxd8 Bf2+ 14.Kh3 (14.Kg4 Ne3+ 15.Kh3 Nxd1 (15... d5+ 16.e6) 16.Rxd1 Rxd8 - + [B+2P vs N]) 14... d6+ 15.e6 (if 15.Qg4 or 15.g4 then 15.. Nf4#) 15... Nf4+ 16.Kg4 Nxe6
A.1) 17.Qb3(d5) Rf4+ 18.Kh3(5) Rh4#.
A.2) 17.Nxe6 Bxe6+ 18.Kg5(h5) Rf5+ 19.Kg4 h5+ 20.Kh3 Rf3#.
B) 13.Qxd5 Rxf7
B.1) 14.Qxc5 Qg5+ 15.Kh3 d6+ and mate in three.
B.2) 14.e6 Bd6+ followed by 15... dxe6 with three extra pawns and attack.
This is all I can do today.
|Jul-27-14|| ||mig55: I found the 0-0 and Bf2, further it was getting too difficult counting for me!|
|Jul-27-14|| ||SimonWebbsTiger: I couldn't help think of the great Reshevsky-Vaganian game the second I saw this position. The White King on g3 is so suggestive!|

after 12...0-0 13.Nxd8 Bf2+ 14.Kh3 d6+ 15.g4 because White threatens a smothered mate or pick up the R on f7. So I had to move the pieces on the Chessgames.com virtual chessboard (to set up the position)

and all becomes clear: after 15.g4 Ne3 16.Qb3+ Kh8 17.Nf7+ Rxf7 18.Qxf7 Bxg4#.
Beautiful game which is new to me. Cue for pun on the Tales of Hoffman theme?
|Jul-27-14|| ||Caissas Clown: Stunning !! Less Giuoco Piano,more Giuoco Rumoroso. We need some Luddites to destroy all the computer programs and return to the romantic era :-).|
|Jul-27-14|| ||RicoChess: David2009 --- after 15.g4 in your variation what should become translucently clear is mate in 1, not 15.Ne3? etc.|
|Jul-27-14|| ||perfidious: Would have been very difficult indeed but for having seen this game, so long ago.|
|Jul-27-14|| ||Penguincw: Just when I thought there would be ideas of taking the knight, getting white into a fork, etc., a queen sacrifice is all that's needed (but not your typical "Monday" puzzle, even though it's Sunday).|
|Jul-27-14|| ||JG27Pyth: 16...Nxe6! Not really an exclam move for a good player, but it's exactly the kind of move I miss -- then play some flabby second best move -- and the opponent wriggles away. |
A really fun game, probably anthologized a zillion times.
<Caissa's Clown <We need some Luddites to destroy all the computer programs and return to the romantic era :-).>>
I'm in. Who's with me?
|Jul-27-14|| ||BOSTER: White had the possibility to return <the gift Nxf2
> at least twice playing 8.Bxf7, or 11
.Bxf7 as the gentleman.

But couldn't find a good reply to
<17 Qd5! ... >
This pin stops Ne6 moving and threatens Qxd6+ which looks pretty okay for
white, (i.e. 17 ... c6? 18 Qxe6 Bxe6 19 Nxe6 leaves white two pawns up but two pieces up!). But it turns out the reply is very simple...
<17 ... Rf5+!>
<18 Kh3/Kh5 Rh4#>
In which case 17 Nxe6 Bxe6+ is forced and the main line all makes perfect sense...

|Jul-27-14|| ||scutigera: I finally register my account, pay my dues, and the very next week I solve my first Sunday puzzle ever! Try it yourselves, kids! It could happen to *you*...|
|Jul-27-14|| ||Cheapo by the Dozen: Black is up 2 pawns, but is poised to lose material, so some kind of combination seems called for.|
Lines that start with Qh4+ and Bf2+, in either order, seem to run afoul of g3.
h5 just seems to leave time for h4, and White's king has a hidey-hole.
Ne6 interferes with Bf2+
But suppose Black just lets the queen go, with 12 ... O-O. The only try I see to decline the queen while still coming out well in material is
13 Qxd5 Rxf7
14 Qxc5 Qg5+
15 Kh3 d6+
Oops. It seems White had better accept the queen. That leads us to
12 ... O-O
13 Nxd8 Bf2+
14 Kh3 Ne3
Black wants to push the d-pawn with discovered check, but he can't do so immediately because of the e6 interposition. White now needs to save his queen, or else get more than just a piece for it; otherwise he'll wind up down a pawn or two.
15 (Q moves generically) Kxd8
16 (Does something or other) d6+
17 g4 h5
leads to Black either mating or gaining material advantage, so White needs to do something with the tempi. But I can't think of anything that works for him.
|Jul-27-14|| ||Cheapo by the Dozen: I missed the Nf4 fork.|

Or 15..Nf4# :)
|Jul-27-14|| ||PJs Studio: At first I thought 12...Bf2+ was the key. Morphshine is right on again though. |
Don't feel bad lost in space - I have never seen this game before either.
|Jul-27-14|| ||TheBish: I got the key move and the rest in a lively round of Guess the Move! (Although I did get some moves wrong on the way to the diagrammed position, but that takes nothing away from a successful completion of a Sunday puzzle.)|
|Jul-27-14|| ||rickycota: <trnbg: What if White had played 17.Qb3 (instead of 17.Nxe6)? With Qb3 White gains time to retreat his king to h3, and I can't see a forced win for black.>|
If white plays 17.Qb3 it comes with Rf4+ and the king has to outs (Kh3 or Kh5) both of which result in mate with Rh4#
|Jul-27-14|| ||M.Hassan: Black to play 12...?
Black is two pawns up.
<if 13.Nxh8 Qg5+ 14.Qg4 Bf2+ 15.Kxf2 Qxg4 and Black Queen is lost>
Apart from astrayed condition of White King, forces seem to be equal
Time to check
would not have ever occured to me!
