Oct-13-02  pawntificator: 17...exd4 would have been better for black I think
Oct-13-02  pawntificator: although white can hold on with 18. Rxd8 dxf3 19. Rxa8 (not Rxf8) Rxa8 and 20. Rxc7 winning back the piece ...fxg2 21. Rxe7 and I think white can still win
Oct-13-02  drukenknight: Pawntiff: so do you think black lost it on the 17th? Larry Evans say that was a "?" move and he also claims that white 20th was the winning move.

Does anyone have any more thoughts on what they think happened? WOod pusher you seem to have a lot of time on your hands.

Oct-13-02  pawntificator: did evans say blacks 17th move was a ? or my exd4 was a ?

White's 20th was a stroke of genius, black should have given up!! Not like you druk, you would have played it out til the bitter end! heh heh

Oct-14-02  drukenknight: Evans gave a ? to blacks 17th and recommends PxN which I guess is dxe4 (there is exd4)

He also gives ? to blacks 19th and yes he does give the 20th an !

So you want to try this game out from the 20th move? Just for a little while, till we get sick of it.

PUt this way: have I ever showed you a game that wasn't interesting? I promise this is interesting.

Oct-14-02  pawntificator: oops I did mean dxe4...there is no exd4 on move 17
Oct-14-02  drukenknight: you ready to play this? the Fisher/Benko thingis confusing me at thispt.
Oct-15-02  pferd: P..r seems to have the right line after 17...exd4. Presumably it would continue 17...exd4 18.Rxd8 dxf3 19.Rxa8 Rxa8 20.Rxc7 Nd8 21.Rxe7 Nc6 22.Rc7 Nxe5 Material is even, but White's possesion of 7th rank gives him all the chances.

If Black has seen what was coming, I guess he would have played 17...exd4 but he was understandably reluctant to enter a position where he had no winning chances, and would be fighting for a draw.

I think the only justification for 13...Na5 can be the advance of the c pawn. Since Black never achieved this, that has to be an error.

Oct-15-02  drukenknight: okay I guess all the commments are in, pretty interesting huh?. I will be back later tonight to show you what I come up with. If anybody is around then, we can play it move by move or I can just post my first move then.

Since we've already spotted 17...exd4 as one improvement I'll have to start from later in the game...Hmmmm.

Oct-16-02  drukenknight: From the final position: 21...f6

  Sneaky: 21 ...f6 22. Nxe7+ Qxe7 23. Bxf8 Qxf8 (...Rxf8 Rxc6) 24. Rxd7, and Black is down too much material to try to salvage the game, in my opinion.
Oct-19-02  Danilomagalhaes: Another continuation can be:
21... Bg5, 22.Bxg5, gxf5, 23.Bf6, Qxe5, 24.Rxe5, h6, 25.Qg3+, Kh7, and 26.Qg7++

Anyway, black is lost...

Oct-20-02  drukenknight: It's always hard for anyone to show possible lines of play because I guess we are always convinced that one side is better so we sort of play lack luster, give up moves for that side.

Black obviously cannot simply play into your hands by 24...Qxf8

21 ...f6 22. Nxe7+ Qxe7 23. Bxf8 Kxf8 (no sense of taking the Q away from hitting the e pawn)

I thought of starting w/ 21...Bg5 like Danil but I gave up on it because of the check on e7.

okay back to you guys.

Oct-21-02  drukenknight: no that wont work I dont think. What if he starts like this:

21....Bb4

Oct-21-02  Danilomagalhaes: Drukenknight, 21...Bb4 is a good move. A possible continuation can be:21... Bb4 2. Ng3 f6 3. Bxf8 Bxf8 4. Ne4 Bg7 5. exf6 Qe6 6. Qg4 Qxg4 7.hxg4 Bh6 8. f7+ Kf8 9. g5 Bg7 10. Rd7 Nd8 11. Nd6 Ra8 12. Rc2 c5 13. Re2

(It´s just put a number 2 before, and exchange the 1 for a 3...)

Oct-21-02  drukenknight: Danil are you going to move the R on d5 first?
Nov-02-02  Danilomagalhaes: I didn´t understand. Did you see something wrong with the moves?
Nov-02-02  Danilomagalhaes: Ah, and my nam is DANILO MAGALHĂES, ok?
Nov-19-02  drukenknight: Hello Danilo. I am just getting back to this game. my question was after 21... Bb4 22. Ng3 arent you worried about cxd5?

  Honza Cervenka: 21...Bb4 22.Ng3 cxd5 23.Qf6 Rxc1+ 24.Kh2 etc.
Nov-21-02  drukenknight: 21...Bb4 22. Ng3 Bf5
Nov-21-02  drukenknight: 21...Bb4 22. Ng3 f5
Nov-28-06  littleshiva: 21 ... Bb4 22. Nd6 Qe7 to avoid Qf6 etc ...
Aug-29-10  sevenseaman: I like this thinking game. 19. Nf5 and 20 Rxd5 puts two pieces en prise and neither can be taken. And Ivkov ambles into a win with 21. Bh6 impaling the R. Its a dare.

  wordfunph: "This is the kind of game that I always admire: a new idea in the opening, an excellent conception of the middle game and, finally, a spectacular king-side attack involving some sacrifices."
