0-0-0 is aggressive?

I want to know how to counter these pawn thrusts really when sides do castle opposite sides because thats i think where i lack. Also, this guy beat me 2 times applying same strategy of pawn thrust h5/h4 followed by 0-0-0 after couple of moves. So any advice or books or links would be appreciated.

And i will post the second game i lost, the similar way but same strategy by the opponent:

For a general treatment of facing that kind of attack it would probably be better to post the other game.  In this game is was less a positional consideration and more to do with tactics.

For example 2...d5 offers white a pawn for no reason.

Ok there is some positional considerations, for example after you lost the right to castle (Nxd8 would be better) it's very tough for black already because you'll be both behind a pawn and behind in development (how to get your rook out).

The other consideration is the move g5.  In the position after 10.Bf4 you should be trying to find a way to get your king out of the center and your rooks connected.  g5 does not solve your development problems, but worse it gives white a way to open a file with h4. 

I don't know how often books mention it, but the opening guidelines about development really last the entire game.  If lines are opened, and your opponent's pieces are better placed (or in case of the opening, if not as many of your pieces are developed) then your position will be worse.  Every time tactics will "magically" appear for your opponent simply because he has more pieces in the game.

So why specifically is black's position so difficult after 15.Bf4?  Is it just because he's lost a pawn or two?  No.  It's because none of his minor pieces (with the exception of the knight on c6) influence the center, his king is stuck in the center, and it's very difficult for his rooks to enter the game.  So again, if you're not used to thinking about positions in this way, tactics will "magically" appear for white and you won't know why.  In this case it doesn't have to do with 0-0-0 or any one move, it's simply because black's pieces are passive or undeveloped in comparison to white's.

-----------------

Actually it can be pretty innocuous to me too.  Once I was playing some training games with a player about 400 poitns below me.  I set up a bad position for myself (where I was tied up defending and my pieces were passive) and we played a game from that position.  He actually did a really good job of attacking me, and to my surprise I lost quickly.  It's just that when we played a real game, my fundamentals were good enough that he never got a strong enough position that let me see his attacking play shine... in this case I thought tactics "magically" never appeared for him!  (forgetting it all goes back to these fundamentals).

So that's my advice to you.  Focus on developing your pieces and controlling the center, castling, and finally connecting your rooks.  Make this your primary goal (other than not losing material to 1 or 2 move threats) for at least the first 10-15 moves of the game.  If you can do it consistently before move 15, then you'll notice the really tough positions to deal with like the one you posted  just don't seem to happen to you anymore... almost like magic :p

Thanks mate.

The second game you lost due to a tactic, nothing to do with 0-0-0 or h5.

But again, you were already in a difficult position when it wasn't necessary to be in one.

This lets me mention a different point.  In the opening, put a pawn in the center (e4 was good by you of course) but also try to keep one in the center.  If you find you don't have a pawn in the center (your exd giving up the center pawn is ok) then make it your goal to put one in the center in the future (exd was only ok because you can play d4 on move 5).

Are there openings were you keep your center pawns back and hit from the side with c4 or c5?  Sure there are!  But IMO until you can play in a principled way (control the center, develop, castle, connect rooks) it's useless to learn the exceptions.  And again these tough positions and tactics will "magically" not appear as often for your opponents.

You may have been afraid of after 4.d4 him playing 4...e4.  But you can't let this kind of move scare you.  Believe me it's much scarier to give up on the center than to have your knight kicked for just 1 move.

wafflemaster if only i could go through my positional principles again i would do so. Need help in that.

:)

What amazes me is when I face, say, 1500-1600 USCF players at the club who don't follow through with their development.  It seems so basic but it's not easy to just do it right every time... and actually I just started to notice how important this can be to a game (even though I've heard the advice since forever).

There's a expert at my club who likes to joke with newer players he faces.  When he clears his back rank, and so connects his rooks before they do, he'll jokingly say "white's rooks are connected first, so he's winning"  I used to think he was a little nuts and laugh to myself but now I think he's trying to remind them to develop their pieces :p

Your positional principles should initially be limited in avoiding dropping all sorts of material in one move. It's apparent that you still have issues spotting and defending against one move threats.

the last sentence enlightened me.now I know the heart ofmy faults I am thinking too long without looking at these threats first Ty will remember it
