How to take advantage???

Play c5 on either move 3 or 4 and you have at least fully equalized (engine says -.1).  Bd7 was just way too passive.  You could still play c5 on move 7, but instead you start making moves with no purpose like re8 and h6.  Playing h6 because maybe someday a bishop might want to go to g5, regardless of whether that would even be a troublesome square for it, is a terrible idea - wastes a move and weakens your kingside for nothing.  By the time you do play c5, it no longer equalizes.  Of course, g6 was a blunder and unnecessary - nbd7 was just fine.  

The usual remedy for a lack of development is to rip open the center and attack the uncastled king. This wasn't that kind of situation though, white can afford those 2 pawn moves, best you can do is play actively with c5 and be happy with full equality.  

Thank you ArtNJ for your informative (and certainly more positive) response!  

lol just cuz ur opponent moved some pawns doesn't mean u win, it just means if u play right, white doesn't get an advanage in the opening, which is usually what white wants, bc white's moving first

Yeah, I'm no great player, but I would describe thatgame like a girl fight with both sides swinging windmill arms.

Yea, c5 attacks the center and B-d7 is not only passive, but it blocks the queens extra protection of the d5 square; instead you could develop your knight to f6 or play g6 planning to move your bishop to g7  attacking the center; sorry my last post didn't have anything positive.

So far, one person has actually contributed to this conversation in a positive way.  i'm not interested in opinions on how "girly" the game was or  "just cuz ur opponent moved some pawns" interpretations.  I am simply asking what I could have done in terms of development.  I'm in no need to hear degrading remarks (mildly or not) outside of constructive criticism or positive information.  If you don't have anything good (or at least constructive/intructive) to say, then don't.  I'm interested in getting better and it seems most of you let your own deprecation get in the way of any real focus.   It's probably why posting on here has it's limitations because too many people can't stick to the point but would rather insert their own pride over the focus.    

Thank you Iusegambis, I appreciate your thoughts.  Ironically, I was writing my last post while you were writing yours  

"how I could have taken advantage of his total lack in development efficiently.  Clearly ..."
and your #8

I read what you have written.
Clear to you then in relation to my comments that follow?

The game is this opening variation:
Queen's Gambit Declined, Marshall defence (D06)
more or less.

http://www.365chess.com/game.php?gid=2882625
is an example of that with black winning ( I do go the extra mile )
I suggest you go through that game for the first twelve moves.

Now go to your game and look at the position after 8. Bd3

(a) your queen's bishop is in the wrong place on d7 it should be b7
(b) your queen's knight has a real problem developing as at best it blocks pawn c5 move
(c) you have developed your king's rook while the above is a tangled mess.

In any event in QGD it is often the case that white's c-pawn goes for black's e-pawn
and the standard counter for black is to push the f-pawn backed by a f8 rook.

Amazingly, your position nearly recovers (14.)
but really with a king side attack starting and your knight on b8 that could support the f6 knight
you make a weakening pawn move ??

You were never in the game.

Please review Mr Raszelenberg (1747) game noting his better piece placement
the way he secured open lines on the queenside and in his case due to symmetrical pawn exchanges was better placed for some queenside/centre tactics that won him the game.

I had the same problem with attacking. and I read all comments which are all taking about your game play c5 bla bla. computer will tell you much better moves that's why this won't help you in a long run. so long run solution go on chess.com drills~attacking where you will get situations of attack. practice that and find your attack pattern. don't worry if you not a paid member just remember the puzzle and play with computer on highest level. I hope this may help you

It's a risk posting losing games in the analysis forum (I know from experience) as games are often commented on with negative, unhelpful one line replies that don't even answer the original question. Occasionally though there are gems of wisdom that should encourage us novices to continue to post our losing games for advice and assistance - In this thread JMurakami has really gone above and beyond with an incredibly helpful analysis of your game

JMurakami is both better then I am and takes more time to be helpful!  However, I do think there is something to be said for focusing on a few things per game at your rating level, rather than overloading the beginner with advanced concepts.  So if you have to take two things to learn here, I'd pick these:  (1) with this formation for black, including d4 & e6, you are blocking in your light square bishop, while white's has freedom of movement.  Just looking at things, you should be wondering how the heck black gets equality.  Answer:  as Jmurkani has explained in much more detail, this formation usually achieves equality only by actively attacking the center with c5 and piece pressure.  It is a tricky thing for beginners, you'll get some lousy games with a disadvantage out of the opening as you learn; (2) never play h6 just because you don't know what else to do and figure h6 is always useful if a bishop might someday be able to go to g5.  Depending on the position, h6 can be either useful/important, a waste of time, and/or weaken your kingside and hurt your position.  It is not a good "I don't know what to do" filler move even though beginners commonly use it as such.  

Play 3...bxc4 4.bxc4 Bb4+ 5.Bd2 Qxd4 (if 5.Nd2 Qxd4) and whether he plays 6.Bxb4 Qxa1 or 6.Qa4+ Nc6 7.Bxb4 Qxa1 you're clearly better.

Yeah, you're correct.
