I thought when he reached 500 he'd stop posting nonsense.

You mean like this?  

You see, this is what you get when you demand things from chess players.  Chess players don't like being told what to do.

As you can imagine, I proposed 11.Nb5!? after somes criticals analysis, to see if it this really playable.  Your actual attempts to refute my 11.Nb5 are refuted !

Quote:


after 15.Kf2 Qc6 : 16.Rxd7! +- with 3 pawns downs!, but the terrible pressure on the queenside will regain material, while black's kingside is sleeping. Same after 15..f5 16.Rxd7! +-

Quote:


14.Bd3 Ne5 (better try might be 14..Qc5 or 14..Qe6, but 15.Qxb7 after both, 15..Qc6 and White is better) 15.Qxb7! and White is +/- after both 15..Nxd3+ or 15..Qxf4+    

Do you agree with my analysis? If yes, you have to find something to the possible improvement (or alternative at least) : 11.Nb5!?

Of course the simplest way to try to refute 11.Nb5 : 11..cxb5 12.Qxb7 seems (=)(this is the first thing I had to analyse to see if 11.Nb5 was playable)

If White want to draw against a stronger opponent, playing a supposed strong defense against the BDG, then 11.Nb5 is the best move here, until someone find a real improvement in the Black side here.

Yes, this is certainly true.  Of course, there are more than two ways to skin this cat.

The line which put me off the 8...e6/10...Nxc3 idea is (more or less):

1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bxf3 7.Qxf3 c6 8.g4 e6 9.g5 Nd5 10.Bd3 Nxc3 11.bxc3 Bd6 12.Rb1 Qe7 13.0-0 b6 14.a4

Black's last couple of moves are a bit suspect, sure, but White's idea in either case is to taget b6 with a4-a5, and after White castles force g6 and play h4-h5.  Alternatively, against 13...0-0 14.c4 seems interesting.  In addition to some central control, there is a clearance theme, to target the weakened dark squares with Bb2 (in some lines, after g6 has been played).

I'd compare this to what seems to be the critical line against 8...h6, something like:

1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bxf3 7.Qxf3 c6 8.g4 h6 9.Be3 e6 10.Bd3 Nbd7 11.0-0 Qc7 12.Rab1 Bd6 13.b4 -- I think this is the right idea; White should immediately challenge Black's plan of castling queenside.  12.Rab1 is a bit committal, though, and maybe Black can be more circumspect.  But I think some of Black's resources are illustrated by 13...0-0-0 14.b5 c5 15.b6 axb6 16.Nb5 Qb8 17.c3 Bh2+ 18.Kh1 Qg3 19.Qxg3 Bxg3

In general, I believe that Black can defend against White's queenside thrusts, and White's weakended kingside comes under question.  Black has all sorts of good plans of opening the kingside with g5/h5.

On the first sentence:  Yes, we have very different ideas, so our assessments are evaluated with emphasis on different considerations.  I am not of the opinion that 8...h6 "completely eliminates White's kingside play."  I think you may be underestimating the difficultly of maneuvers involving queenside castling in this situation.  I see ...h6 as more of a "hook" in Black's position, than an effective prophylactic device.  The comment on ...g6 comes less from general consideration and more from necessity.  For one, black often wants to aim for an ...e5 break, and another consideration is if black is castling kingside, this move is often a must.  I don't believe in strict adherence to principles, but I am simply conveying my "feel" for the postion.  Black often has to have concrete forms of defense in mind, and I don't think just planning queenside castling is enough.  What are black's plans to consolidate?  When playing against the BDG, it is important to have an eye towards this, since sometimes the plan may be too slow.  I have had this happen a few times!

Another thing to note is g4-g5 may not necessarily be a great strength for White, and I think Black can often demonstrate it to be a weakness.  White always runs the risk of being overextended in these position.  These are currently my views on position, which seem to be diametrically opposed to yours!  I like to see conflicting views on a position, since they might indicate where I am wrong.

YOU  move on to other  openings, Smyslov Fan.  We  will continue to  debate the correct moves until we establish what is correct and  what is not.
   Me, I play a whole slew of other openings besides the BDG.

These are both good points, but I think that this position cannot be treated just by those general principles, and I think that the resulting positions support this claim.

8...h6 has the advantage that it completely eliminates White's kingside play.  Sure, usually moving pawns like this is a weakness, but here the main threat was g4-g5 exposing f7.  Since the knight sits well on f6 shielding the pawn, it makes sense to prevent this advance.  Moreover, h4-g5 does not seem to be a realizable plan.  Since Black does not intend to castle kingside anyway, king safety isn't really an issue.  Critical here is that Black can now develop his pieces more harmoniously; the knight stays on f6 protecting f7, so Nbd7 is easy to play even after Qc7.  (Cf: 8...e6 lines where N(b)d7 is harder to come by, and Black castles kingside.)

I am less impressed with the idea that the light squares are weakened here; c6/e6 control the central squares well, and White has no way of exploiting the slight weakness of g6.  Moreover, this is more than offset, in my view, with the bind that Black has on the kingside dark squares after Qc7/Bd6.  White's dark bishop seems quite prospectless.
