how to exploit a space advantage?

hi everyone, here is a game which i would like to share it with everyone.it contains my thoughts about some moves of the game.

kindly go through my notes and game and please tell how could i have handled the position occured in this game.

in this game, i have position extended quite deep into white's side in other words, i had some space advantage yet i was not able to win this game.

i seriously want to know  how should i have used the space advantage?

You need piece activity for a space advantage to have any meaning.  All you did was release the tension and ignore development.  A well timed f4 strikes at the neck of your pawn chain and you created many holes in your position quite early.  5.c4 was bad because it was too committal and takes striking the head of the pawn chain with c3 off the table.  Sometimes it's better to strike at the head but usually striking the base is the best policy.  Since the base is your g7 pawn it isn't realistic, and the body at f6 would involve him pushing the g-pawn, too many concessions than striking the body of the chain is worth.  So that leaves 5.f4! as the best move to strike your chain. 

3...Nf6 looks correct simply supporting the pawn with a piece.

Correct, you should play on the queenside, but don't neglect development.  5...Be6! wanting to cover your weak a2-g8 diagonal!  Quite a good idea and if Bh3 hoping to exchange off the defender of your weak light squares you can simply play ...Bf7. 

7...Qd7 is seemingly sensible, but it doesn't do much and hands white a glaring  sac with 8.Nxd4!,exd4 9.e5 hitting both your vulnerable b-pawn (the rook is stuck) and currently attacks the bishop. It isn't an easy tactic to spot however especially at internet time controls.9...Nc6 you're still in the game however, but it's tough to defend here as black.

9.Nxd4,exd4 10.e5 works again, but isn't as potent as you developed.  10...Nbc6 11.exd6,cxd6

10...a6! exploits his overextending pawns without the piece play to justify it.  after 11.bxa6,Rxa6 you punched out nicely and have some queenside pressure going on.

17...f5?? is your first real blunder, as it's critical to keep g5 under wraps. 

18.Ng5,Qe8 19.exf5,Bxf5 20.Bd5+,Kh8 21.Nxh7 and the knight cannot be taken due to 22.Qh5# Your king is totally unsafe and white now dominates those critical weak light squares. 

And like Umbrella says you should generally avoid exchanges when you have space as when you're cramped pieces get in each others' way.  Not only that but in an endgame the pawns are closer to the other guy's king. 

this was not a bullet game. it was a game of 5 min blitz.

anyways, thanks for your advice

frankiebones7983, thegreatoogieboogie and umbrella_corporation.

but can anyone tell me whether the move 38.Qxe2+ was correct ??

Qxe2 was probably okay, as the game was heading for a draw, especially since a draw with black when you're 400 points outrated is a very nice result. 

I see from your annotations that you hold on to concepts very well, so I'll give you some of that advice instead of move-by-move analysis, which OogieBoogie did a nice job of already.

Everyone says when you have a space advantage, don't trade pieces, which is in general a good idea. I'd like to add that the reason a space advantage is good is that you can maneuver more quickly, and better than your opponent.

Identify a target in your opponent's position, and position your pieces to attack it. He'll defend it. You now can pick a -different- target, and remaneuver your pieces to attack that, and he won't be able to shift his pieces to defend as quickly as you can to attack it. You often have to shift targets like this. See this game for an example of white shifting targets from the f-file to the queenside faster than black could react: http://www.chess.com/echess/game?id=78080444

With more space, you have the mobility to create and respond to threats better than your opponent. Overwhelm him with a barrage of threats (not one-move threats, but real threats on real targets), and eventually you'll be able to make one stick. For an extreme example of having more mobility, see this game. After about move 15, black has trouble finding any constructive move, and white can take his time: http://www.chess.com/echess/game?id=55199108  (This is also a good example of an outposted knight being absolutely devastating.)

Also, more space is an advantage in the middlegame, but it can b ecome a liability if you lose control of your space and allow your opponent in. See this game for an example of white losing control over his space, and black jumping in. Once black got behind the pawns and white couldn't kick him out, it was over: http://www.chess.com/echess/game?id=40154058
