Thanks much for the answer!  I'm looking for a good opposite side castling ECO for a vote chess game. 

To Mike Doyle:

I you look in the Chess.com "Game Explorer" (under the "Learn" tab above), you will see that the line you give has been played many times and, as nearly as I can tell, White seems to winning the lion's share of those games.  I used to play the Nimzo-Indian as Black a long time ago (I switched to the King's Indian and like it a lot better), but I don't recall having ever played all the way up to the position you give.  It seems White is able to exert central pressure very rapidly.  For example, if White plays Nb5 and Ne4, he suddenly has 4 men attacking the hole on d6.  And as we all know, an attack on the wing will always fail if the center is not blocked and you don't have control of it.

Thanks for the question!

Has any one ever played E23 Stahlberg Variation, Nimzo-Indian 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qb3 c5 5.dxc5 Nc6 6.Nf3 Ne4 7.Bd2 Nxd2 8.Nxd2 O-O 9.O-O-O?  Does black have the initiative here after opp. side castling with first move or is white in a better position?

that attack on black king was splendid and relentless.thanks a lot.

Thanks. Abundantly persuasive.

It would be helpful if you put the variations in the move list, rather than in the notes.

Very instructive ... as usual!

To Hackattack:

Once you play h4, you are kind of committed to castling queenside, since you have weakened your kingside somewhat.  The only reason to play h4 before you castle is to possibly slip in h5 before that gets prevented by ...h5.  I do that in the Yugoslav Attack vs. the Dragon Sicilian, with which I am sure you are familiar (ceajee vs. hackattack, Nov. 1 (he should have played 17. Bh6, not 17. f4)).  In this game, it's just a transposition with no significance.  But you never know if someone will panic and play a weird move when they see h4.

so before opposite side castling, would you recommend playing a move like h4 to see how the opponent will react?

Hi spassky good to have you back, you been away for awhile have you ?

very pragmatical

To Dimitrije_Mandic:

I edit my posts with another program that doesn't allow integrating the variations in with the main line.  To do that, I would have to re-enter the whole thing into the chess.com viewer, rather that cutting and pasting it from my other blog (at www.brucetill.com). 

As a compromise, why not try using the analysis board feature of the chess.com posts?  Right under the viewer where the moves appear, there is a button called "Analyse".  Clicking on this opens a new board (with the moves of the game) where you can move the pieces around.  So just click the move buttons to get to the position where the analysis note is, then read the note in one window and play it over in the other.  You can resize the windows so that they appear side by side on your screen.  I tried it already and it's pretty easy.  Anyway, the majority of my notes are just words, and the ones with variations are usually just a move or two.  I know move 20 of this post had a longer variation, since it was a mate in 10, but that's unusual for my my posts. 

Sorry about any inconvenience, and I hope my dual board solution works for you (post another comment if you have trouble).  Thanks for reading my articles!  And don't forget to visit my other sites:

I'm probably not the first one to ask this, mr. Till, but would you mind inserting your variations into the viewer? I find this more practical than to visualize at all costs, since those who want to visualize can just look at the variations, and then try to play them inside their heads. Thanks in advance!

Is that Gary Stevens the Everton football player? :)

Btw good article!

     This is a nice win from my favorite decade.  I love to castle queenside and then charge the opponent's king.  One can often sacrifice a pawn, knight, or bishop and get the
win, but if it doesn't happen in under 30 moves the attack may fail.
     I hope you write some new articles for Chess.com, I enjoy your positive-thinking approach and your aggressive style.

Great game and an excellent attack!

Great article! Very insightful and helpfull, since I prefer castling on the queen side, just because of its attacking nature.
