  Once: <JG27Pyth> Now that is one weird position! Thanks for finding it; it made me smile.
Feb-06-09  YouRang: Well, I got the general idea. Not seeing any good immediate attack, I decided that I needed to get my queen involved, and I saw a good way to do that forcefully with <20.Nxh7!>, after which I assume <20...Kxh7>.

For my knight, I've eaten a key defensive pawn and exposed black's king.

Now my queen comes in *with check*: <21.Qh3+ Kg8>. Here I went with the fairly obvious <22.Qh6> putting a lot of heat on Pg7.

What can black do? 22...Rff7 looks losing (23.Nxf7 Kxf7 24.Rxf7+ Ke8 25.Rg8+ Nf8 26.Qxf7 ~#), so I think he needs to sac a knight back to remove an attacker: <22...Nxf2+ 23.Rxf2>.

At this point, I've recovered my material, and I have a tremendous attack underway, so already I'm pleased with 20.Nxh7.

It's not perfectly clear what black should do. I'm threating to either bring my rook back from f2 to g2, or bring a rook to the h-file (e.g. Rf3 & Rh3). So, I think he better exchange off another attacker via <23...Nxe5 24.fxe5>, which also clears the 7th rank for black's queen to help out defensively.

Now what? ...Board vision fading...

I'm guessing <24...Qc7> (support Pg7) <25.Rf3> (threat: Rh3 to support Q down h-file). But who cares, I'm happy with the position and I'm pretty sure I'm winning. :-)

  Ladolcevita: Its hard to say why i cant watch the game from the eternal "Java Icon".....But i feel whether i miss it or not,i'm a stupid patzer in the endless world of chess.
Feb-06-09  fouard: 20 Nxe6 seems promising. Black can't just let the pawn go, nor ignore White's threats, so I believe 20...Rxe6 has to be played. To this White responds 21 Rxg7+, forcing 21...Kh8. Now comes 22 Rxd7. Black can't keep White's other rook out of g7, and if he tries 22...Rh6 or Nf6, White wins an exchange with Nf7+. White is up enough material to win, even if Qh3 weren't looming at this point.

I get the same problem from time to time, even having the latest version of Java installed. I find it helps if I quit IE and come back again. Sometimes.

  benveniste: Puzzles like this one prove to me once again why I'm a wood pusher. I convinced myself that 20. ♘xh7 followed by 21. ♕h3 was the right answer, but I couldn't visualize the whole sequence.
Feb-06-09  Patriot: <fouard: 20 Nxe6 seems promising. Black can't just let the pawn go, nor ignore White's threats, so I believe 20...Rxe6 has to be played.>

I also wanted to play 20.Nxe6 at first, but saw that black has the zwischenzug 20...Nxf2+ 21.Rxf2 Rxe6.

But if your line occurred, it's enough to see that 22.Rxd7 is good for white even though 22.Rg8+ Rxg8 23.Nf7 is mate. At first I didn't see the mate in that line and just decided that 22.Rxd7 is convincing enough and stopped analyzing, but then noticed 20...Nxf2+ refutes everything from the start.

Feb-06-09  fouard: Patriot: Good point. A nasty rebuttal Nxf2+ is. Thanx!
Feb-06-09  Primoman: chris1clark - After 2...hxg6 3.Qh3,nef6 and white is neutralized and down a piece.

Feb-06-09  SamAtoms1980: Darn. I weighed the two knight sacrifice candidates and finally went with 20 Nxe6 with a view to 20 ... Rxe6 21 Rxg7+ Kh8 22 Qh3 and the roller is on. Stupid zwischenzugs. I turned down 20 Nxh7 because after 20 ... Kxh7 21 Qh3+ Kg8 22 Ng6 Kf7 23 Qh5 Ndf6 and the bomb defuses (24 Nxe7+ Nxh5), missing the fact that 21 Ng6 attacks an undefended rook. That allows White to gain a move and keeps the Black king from running away.

On these problems with two attractive starting move candidates, I may have to get out my lucky dime.

Feb-06-09  SamAtoms1980: <richard littlewood: doesnt 20 ... Nxe5 save black? then 21 f xe5 K x h7
22 Q h3+ K g8
and black is a knight up>

I fixed the move numbers because I presume that's what you mean. After 20 Nxh7 Nxe5 21 Nxf8! and Black has lost the exchange for nada. If 21 ... Qxf8 22 fxe5.

Black's hanging knight does have one target and he can try to keep things interesting and extend its brief term as a desperado with: 21 ... Ng4 22 Ng6 Nexf2+ 23 Rxf2 Nxf2+ 24 Kg2 - - but now the rebel knight is lost - - because White threatens 25 Nxe7+ forking King and Queen.

Feb-06-09  eatitorbeatit: Even though my tactics were sloppish finally after half an hour (it seemed like) the white king was captured by the queen which had been left with nothing to do. Qh6+,Kgh!

How about 23.Nxe7 instead? White gets at least 2 pawns and the exchange for a knight. For instance, 23.Nxe7 Kxe7 24.Rxg7+ and if the king moves then white moves the queen to avoid a royal fork. Otherwise, 24...Rf7 25.Rxf7+ Kxf7 26.Qh7+ with decisive effect.

Feb-06-09  richard littlewood: < SamAtoms1980: <richard littlewood: doesnt 20 ... Nxe5 save black? then 21 f xe5 K x h7 22 Q h3+ K g8 and black is a knight up>

you are right on the first part, but black can still pursue the f2 square after: 20 Nxh7 Nxe5 21 Nxf8 Ng4 Ng6 now black can retreat his rook to e8 and still have time to attack f2 so 22 ...Re8 white cannot defend f2
if 23 Rf1 black forks the rook and queen with 23 ... Nd2 and if Qf3 black can force the queen away with 23 ... Nd2

so he can force a draw or recover the exchange

  johnlspouge: Friday (Difficult):

J Levitt vs J D Tisdall, 1990 (20.?)

White to play and win.

Material: Even. The Black Kg8 has 1 legal move. White has a battery Rg1 and Rg2 facing Kg8 on the g-file, obscured by the White Ng5 and Black Pg7, suggesting clearance of Ng5. The White outpost Ne5 and Ng5 control light squares in the Black K-position, while the White Qb3 can move along the open 3-rd rank to, e.g., the semi-open h-file, and is on the same diagonal as Kg8, obscured by Pd5 and Pe6. The White Kh1 is open to checks Nxf7+ or Ng6+, but is otherwise snug in the corner.

Candidates (20.): Nxe6, Nxh7, Qh3, Nxd7

After the two obvious candidates 20.Nxe6 and 20.Nxh7, I could not find a winning response against 20…Nxf7+, which deflects Rg2. I timed out. Toga confirms 20.Nxh7 as a winner, so I will have to see what I missed.

  johnlspouge: I exhausted myself on 20.Nxe6: the eventual Ne5-g6 winning the exchange handles Black if he gives back the material immediately.
Feb-06-09  WhiteRook48: thinking Nxh7 but again I overlooked the follow-up
Feb-06-09  SamAtoms1980: <richard littlewood: < SamAtoms1980: <richard littlewood: doesnt 20 ...

Nd2 and if Qf3 black can force the queen away with 23 ... Nd2

so he can force a draw or recover the exchange>

23 Qf3 Nd2 24 Qh3! and White can swing into position with the threat on f2 at bay.

If 24 ... Ne4 25 Qh8+ Kf7 26 Ne5+ Ke7 (26 ... Nxe5 27 Qxg7 mate) 27 Qxg7+ Kd8 28 Nf7+ Kc7 29 Nd6+ Qd7 30 Qxd7+ Kxd7 31 Nxe8 and White has it all made.

This site needs tighter parental controls. As God is my witness, she is managing to do this entirely on her own.

Excuse me while I talk to my second daughter...

Feb-06-09  TheBish: J Levitt vs J D Tisdall, 1990

White to play (20.?) "Difficult" (3 stars)

My first serious candidate move was 20. Nxe6!?, with the idea of 20...Rxe6 21. Rxg7+ Kh8 22. Nxd7 Nxf2+ 23. Kg2 Kxg7 24. Kxf2+ Rg6 25. Rxg6+ hxg6 26. Nxf8 Qxf8, which only nets a pawn, but there is another problem with this line: Black can simply play 20...Nxf2+!, forcing 21. Rxf2 Rxe6, and there is no follow-up.

A much better plan of attack is 20. Nxh7!, which does several things: 1) weakens the Black king position; 2) clears the g-file for the rook brigade and 3) gains a critical tempo for the white queen to enter the theater of attack.

After 20. Nxh7! Kxh7 (or Nxe5 21. Nxf8 winning an exchange, since 21...Ng4 22. Ng6 Ngxf2+ 23. Rxf2 Nxf2+ 24. Kg2 Rf7 25. Kxf2 wins a knight) 21. Qh3+ Kg8 22. Qh6! with an overwhelming attack, e.g. 22...Rff7 23. Nxf7 Nxf2+ (or 23...Rxf7? 24. Rxg7+ Kf8 25. Qh8+, winning the queen, or 23...Kxf7? 24. Rxg7+ Ke8 [Kf8 25. Qh8#] 25. Rg8+) 24. Rxf2 Rxf7 25. Rfg2 Qf8 26. Qxe6, and White cleans up. Time to check!

Feb-06-09  TheBish: Well, in my haste (see my previous note), after 20. Nxh7! Kxh7 21. Qh3+ (for some reason I didn't give much time to 21. Ng6!) Kg8 22. Qh6 Nxf2+! 23. Rxf2, I missed the simple 23...Nxe5 (since one rook was diverted off the g-file, Black now has time to remove an attacker) 24. fxe5, and White has to be better, but not as clearly winning as in the game. That being said, I believe White has a winning plan in Rf2-f3-h3, threatening Qh8+ Kf7 Qxg7+ Ke8 Qxf8+! Kxf8 Rh8+ Kf7 Rxc8, netting a rook. Black will have to run with his king, giving up the g-pawn, which will ultimately win in a king and pawn endgame, should White manage to trade all the pieces off.

The moral is: If you see a good move, look for a better one!
