It is amusing to read how the author sarcastically praises your book. Note that every single product in that link has been given a very positive review by him, e.g. he claims that 'Play 1.b4' is a very important reference work and that 'Chess for Scoundreds' is a must for every chess player, both of which are incorrect.

It's not sarcastic; as you noticed, Elburg praises every book he "reviews".

Dear Sloughter:

I appreciate your hard work,but please spend more time with your engine to make conclusions:
I did only look at this line:
8.Qf3 Be7 9.Bxc6ch Nxc6 10.Qxc6ch Bd7 11.Qc4 O-O 12.Qe2 Bc6 13.Nf3 e4 14.Ne5 Ba4 15.d3 Qa5 ? Sorry to say,but this reminds me of Patzer sees a check,patzer plays a check.Much more to the point is:

15....Rc8!
and after:
16 Nc4 Bc2!
17 Qc2 ed3
white faces a tough defense for a draw.





Why Ng4 ? You should,by now, know that the optimal square is d5.So 10...Nd5! and if you play 11 Nh3 f5! with the idea of e4, and white is not a happy camper.

Sloughter, what a bad memory: you already gave 8.Qf3 h6 9.Ne4 where I already gave 9..Nd5 where we played some moves and you didn't find anything here. But no, you come back again with a "poor" move for Black with 9..Nxe4.

Then you give 8.Qf3 Rb8 9.Be2 (your new try) where 9..Bg4 should not be very good. I would play 9..Be7 I think. You give 9..h6 too but I don't see Black should mix 8..Tb8 with 9..h6, 8..h6 may be better for that. About 8.Qf3 Bd7 or 8..Qd5 I don't care watching that as Black because it's clearly not the main defense and it may indeed be good for White. 8..cxd5 is known to be doubtful too.

I see you got a new idea here too: 8.Qf3 Be7 9.Bxc6+ Nxc6 10.Qxc6+ Bd7 11.Qc4 0-0 12.Qe2 (almost a new move here), and Black has many moves to equalize. Even 12..Rc8 is still good here (as in the line 12.Nc3 Rc8) where it seems to me that the best move for White is still 13.Nc3 with the transposition (if 13.d3, 13..Bb4+! 14.c3 Bb5! with strong pressure).

Oh and don't forget about our game! It's your turn since a while!

GM:  I am excited to see your ideas!
Student: yes, I think they are really good.
GM:  Wonderful!  That is a nice idea.
Student: Do you think I can get better despite the fact that I am stagnating like 3 day old fish?
GM:  Of course!  I think what you need to do is take more classes with me.  Also, this book I wrote could prove very helpful.
Student: Wow.  Thanks for being so generous to sell me the stuff you have on hand.
GM:  Fresh Fish!

Customer: That does not look fresh,  How old is it?
Fish Monger:  It is fresh, sir!
Customer: But it looks and smells nasty and is rotting!
Fish Monger:  I assure you it is fresh, sir!
Customer: I don't know...looks 3 days old.
Fish Monger:  Nonsense!  No one would buy Fish that is 3 days old.
Customer:  Ok, I'll buy it.

GM Alburt needs to tell this guy some truths and stop being so disingenuous no matter how much he likes those Pastrami sandwiches because there are better and more noble ways to make a buck in America than leading on some poor sap the way a buxom and desirous stripper leads on her pathetic cash cow.

sloughter wrote on 02/10/09 at 12:43:27:
Here is the definitive analysis and practical play in the 8.Nh3 variation. From a book I published in 1999, 

"Theory pretty much ends with the move sequence 5.exd5 Nd4 6.c3 b5 7.Bf1 Nxd5 8.Nh3 although the author and GM Alburt analyzed this variation in detail in EMPIRE CHESS, Winter 1988 p.6. We also recognize the contributions of ICM van der Tak, NM Alon Bochman, FM Craig Mar and the pretty tactical shot pointed out by Pete Tamburro (8...Bg4 9.Qxg4?? (Bb5ch!) Nc2ch 9.Kd1?? Nce3ch! -+), and minor computer-assessed analysis of 8.Nh3 Bxh3 by NM Eric Schiller."

"GM's Alburt's concept, first recognized in the game Alburt-Gulko, USSR Student Cham., Dubna, 1970 is a profound idea that places the onus on Black to equalize. The first point is that White prepares to exhange off a pair of Knights after say Ne6/Nef4. This is obviously not possible in the variation 8.Ne4 Ne6 9.Bxb5ch Bd7 10.Qa4 Nef4 when Black has compensation. We now follow Alburt-Gulko: 8...Ne6 9.Bxb5ch Bd7 10.Bxd7ch; we prefer 10.Qa4 see below: 10...Qd7 11.O-O Be7 12.Qe2 Bf6?! 13.d3 (d4 +/=) O-O 14,Ba3 Rfe8. Black has a variety of alternatives to 8...Ne6 e.g. 8...Nc6 9.Bxb5 +/- or 8...Bg4 9.Bxb5ch Nxb5 10.Qxg4 or 8...Nf5 which leaves the Knight on a peculiar square and, of course, 9.Bxb5ch wins a pawn. This narrows the choices to 8.Nh3 Bxh3!? and 8...Ne6.  If 8...Bxh3 9.cxd4 (gxh3 Qh4! with comp: ICM van der Tak) 9...Bd7 (To defend b5). If now 10.dxe5 +/= GM Alburt. Black only has partial compensation for the pawn, but, NM Eric Schiller maintains that Black is okay after 10...Qh4. This is difficult to accept after 10.Nc3! White hits d5 and bv5; if 11...Nxc3 12.dxc3 Qe4ch 13.Qe2 +/-. and on 11...c6 12.Nxd5 cxd5 13.Be2 Qg5 14.O-O Qxe5? 15.Re1 looks pretty good for White. Other tries like 10...Nb4 or Be7 don't promise Black very much either.

"Thus the stem game, Alburt-Gulko appears to have revealed the main line very early. The key continuation for White appears to be 8.Nh3 Ne6 9.Bxb5ch Bd7 10.Qa4!. White either forces Black to accept an inferior middlegame or an inferior endgame: 10...Nb6 11.Bd7ch Nxd7 12.d4 exd4 13.cxd4 Be7 14.Nc3 O-O 15.d5 +/=. 

"Black avoids an endgame but is not out of the woods yet; with best play, White should win this. There are a host of similar endings Black can achieve a pawn down, with no real compensation for the pawn. Obviously, this is unacceptable to the majority of chess players.

Black can also try 8...Ne6 9.Bxb5ch Bd7 10.Qa4 Nc5 11.Bxd7ch Nxd7 12.O-O Be7 13.d4 +/= Black is shy of equality. The decision to enter an endgame is only marginally better: 8...Ne6 9.Bxb5ch Bd7 10.Qa4 Nc5 11.Bxd7ch Qxd7 12.Qxd7ch Kxd7 13.d4! (Ke2 e4 14.Na3 Nd3 15.Nc2 Nd5f4ch 16.Nxf4 Nxf4ch 17.Ke3 Nd3: and NM Bochman wonders if White can dig out) 13...exd4 14.cxd4 (O-O dxc3 =) 15.Nc3! Nxd4 (Nb4 16.d5 +/- or Nxc3 16.bxc3 +/- Evaluations by GM Alburt) 16.Nxd5 Nc2ch 17.Kd1 Nxa1 18.Bd2! +/= (GM Alburt)

"One final try is 10.Qa4 Bc5 but 11.d3 f5 +/= (GM Alburt)" There doesn't appear to be any simple pathway to equality for Black here.sloughter wrote on 02/08/09 at 21:10:54:
In order to keep the analyzed lines in one place, here is a way to avoid the complicatons of 8.Ne4 Ne6 i.e. 8.Nh3!? Bxh3 (Ne6 9.Bxb5ch Bd7 10.Qa4 & White is better than the 8.Ne4 line because he can oppose Knights when one of them gets to f4) 9.cxd4! Bd7 10.dxe5 +/= (I'll have to check my analysis here; Black may have a draw by repetition in one of the subvariations). So far, not one menber of this post has tried to engage in an analytical battle over even one variation. Since many are controversial e.g. my latest attempt at an advantage against 8.Ne4 Ne6!sloughter wrote on 02/01/09 at 20:00:15:

The video highlights one of several holes in your childish attempt at refutation.


May I suggest that we all remain civil?  Even chilldish, even obnoxious attempts are deserving of respect.  We all love chess.

I think Sloughter has more "cooks" and "innovations" in store for us.

As this is something of an intermission, let's all go to the lobby and ask each other questions like 'How does Black complicate the position to generate winning chances after e4 e5 Nf3 Nc6 Bb5 a6 Ba4 Nf6 0-0 b5 Bb3 Bc5 d3?' and 'did you read Moody's first? It got a rave review from the fellow who wrote that dreadful pamphlet on the Marshall Attack'.

 Curtain is going up, time to retake our seats.

'This guy is for real?'

Apparently so. 

It's amusing that such a piece of performance art can attract 5 posts in only half an hour.
  

All our dreams come true if we have the courage to pursue them.
