I've no idea on this one

A couple things I noticed:

(1) You neglected to play 3...d5. See my comment and examples I posted earlier today:

http://www.chess.com/forum/view/game-analysis/i-checkmated-without-seeing-it

(2) You castled into a pawn storm! Some clues you should have castled on the queenside (or maybe not at all) were that your important kingside defender--your king's knight--was displaced from f6 (stemming from the first mistake I mentioned), so it could not protect that side adequately, and White was already launching pawns at you on that side via g4. Also, the center was locked up, which means you couldn't counterattack in the center, which is a common response to a flank attack.

After White's 6th move it's a French Defense Advanced Variation, and you might've tried center and Q-side pressure with Qb3.

One of Black's main ideas in the French advance is the destruction of White's pawn centre. The locked pawn chain gives White space on the kingside makes it difficult for Black's pieces to defend a kingside attack.

A common plan is to attack the d4 pawn with pieces. For example with knights on c6 and f5 and queen on b6. If Black cannot put enough pressure on d4 then another plan is to attack e5 with f6.

This breaks up White's central pawns but sometimes leaves Black's kingside exposed. In these positions Black often delays castling as the king is sometimes safer in the centre.

Thanks, some really good feedback, all of my questions got answered!!!  I'll definately be looking to play d5 when I see c3 infuture.

Obscurist & DavidIreland3141 I don't understand the reason for  ..8(9) Bd7 or is this to prevent the b pawn moving to keep castling long an option?

Also I don't understand why move 10 is the time to play Bxc3+.  I think maybes its to do with preventing whites castling long options & maybe later its time to think more about defense?

thanks Fiveofswords

Bd7 does several things. It develops a piece, it retains the options of keeping your king in the centre or castling queenside, it unpins the knight, it allows for a possible exchange of bishops, and if White takes on c6 it gives your the option of recapturing with the bishop or the pawn. It's a flexible developing move in a position where castling kingside may be risky.

With 10..Bxc3 11.bxc3 f6 the pawn structure changes benefit Black more than White. White's c3 pawn is weak and becomes a target and White's pawn chain gets broken up, opening up the position.

Thanks Obscurist 

Wow, this is the thread that keeps on giving!!!

Diakonia: Thanks for the analysis & for helping me understand the f pawn break.  I like 10 Qa5, looks like a strong move.  I've read a lot about attacking on the flanks when the centre is locked but it seems to take me a lot of chess experience before any concepts genuinely sink in.  I have to confess I don't understand 7.h5, I guess if gxh conduct your own kingside attack now your rook is free?  9..Nf5 I saw this opportunity in the game & its a move I often play but I would be avoiding it where it breaks my pawn structure but here you welcome it because you are slightly ahead on development, looks like its going to get wild!!  Would you have a general game plan after 10 exf5?  ..Bd7, Castle long, Be7 followed by f6 to break-up whites centre?

What's the Greek gift sacrifice?  I guess its some kind of knight sacrifice?

RasputinTheMad:
Your analysis made me laugh!  How often have I seen member analysis videos on chess.com "why oh why did black play Bb4 to then not take & then why play Bxc5 if he plays Ba5???  I tried to understand his logic but gave-up......."  You give me too much credit I played 8..Bb4 because I thought white was going to castle queen side & I wanted to break-up the queen side pawn structure.  Although I'm aware of the concept of creating backward pawns on semi-open files (usually after I gift this to my opp) I didn't see it here.  Because your analysis was so good I'm going to give you the insidght into the workings of a dunce's mind.....

9..Ba5 so by now I realize white isn't castling kingside & I should use the bishop to attack the d-pawn (I realize now breaking the centre is key).

14..bxc3 I've given-up, lost all hope, I'm just going to trade what I can & pray...

I really like the 8..Qb6 move & have started playing it, I had noticed it ties the bishop down but hadn't clocked that meant removing a defender of d4.

11..f6!  I think this move is pretty much a "!" at pretty much any point after 7.g4?

some general thoughts..

8... Bb4: I would have placed it on e7 to assist f7-f6/f5 and prevent some of his kingside attack.

10...Ba5: Later you are taking on c3 so this is definitely a loss of tempo. I would have played it back to e7.

11...a6: His white squared bishop is misplaced. It should have been on the b1-h7 diagonal. with a6 and b5 you are forcing him to develop his bishop to a better square.
