I keep dying in chess

I keep dying when i play chess!  i know i there are somthings  can get better at, but i keep dying no matter what. sometimes i do pretty good and the clock actually runs out, but that doesnt happen enough.   i think I should get better with my pwns, (get them to the other guys back row faster) but they keep getting killed.  here is an axample (i try to reorganize them):

.  If there are any tips you can offer that would be good my goal is to be really good and stop looking at the game over screen!

30 seconds of my life I won't get back looking at this game...

OP - "I keep dying in chess"

Sort of a chess version of "Groundhog Day"?

thanks for the help strangmover.  It was a lot longer than 30 seconds before i died in this game, but it was a hard loss to take.  I hope there is someone here who knows how to play this certain line better and can help.

@OP, what was the time control?

just the regular time controllers that come with the website.

Uh, OK. I found it anyway - it was a 5|5 game. I suspect that you need to play slower games. 5 min games just don't give you enough time to think about your moves. Try at least 20 minute games, or even longer, if you can find them.

Why 15.Bb5? You should take his knight, not need to go away with the bishop and give him a move like c6 for free.

Well, really, you just need to work on your tactics - You're hanging lots of pieces in your game. Maybe if you take more time, your tactical errors will be fewer.

Already before after 9...Qe7 you could just take the bishop on c5 and push the bishop away with f3 with a nice position.

Oh, are we being pwned or sumthin'?

The blah blah can sometimes be interesting...

Really? You are a little bit rude my friend

Why 5... Nd4? You see you're leaving the pawn undefended, but even if it were defended what does that move accomplish? What if White takes it? Now you must recapture with with the Bishop which will be hit with c3 which helps White prepare for d4, or you must recapture with the pawn and then your pawn would block your Bishop? After 8. Be3 are you worried at all about your opponent swapping on c5 and picking on your weak pawns? What is with move 10 and 11? 10... Be2 has no target. If White is able White would like to play Re1 anyway, this move lets them do it with tempo and the Bishop is short of squares. The Bishop will have to retreat to h5. You play 11... Nh5 instead and now the Bishop is completely trapped and will be lost. 16... Rd8? You're giving your opponent an exchange for nothing. Rooks are better than Bishops, and you're already down a piece you do don't want to offer trades. 17... f5? had you already given up the game at this point?

just work on tactics....

And understanding if your piece is hanging...

 Right off the bat.  I can say that more than a few of your moves just don't make sense.  I guess a good first start might be to ask yourself "why am I making this move?".  

Lets start with 5. O-O Nd4.  Why is the knight going to d4?  True it would be nice to have a knight in the center...but can you keep it there?  Are there other more important things to be doing?  Furthermore, was there a reason to prefer keeping it on it's original square?  First note that when you moved the knight you removed the protection of the e5 pawn (hence white could respond Nxe5 with advantage); in this type of setup controlling the center is important so we want to keep that pawn!  Furthermore the knight can be ejected by c3, a move that white (or at least should) wants to play to prepare d4 and take the center!  Perhaps the even bigger sin here is you're behind in development and moving a piece twice in the opening.  Don't try to be aggressive if you haven't completed development.   Much stronger here would be O-O or d6.

Ok all that out of the way we arrive at Bg4.  You're developing with tempo here, and that's probably not a sin.  I and the computer both agree that a dark squared bishop trade is probably strongest to avoid doubled pawns and gain some tempo on white's recapture.  And Bg4 runs into Qg3, which is not trivial to deal with after h3. 

9.  Qe7 similar complaints.  I don't see a compelling reason to move the queen there.  I still prefer trading off the bishops here.  I might give you a slight pass here if your intent was to follow up with O-O-O and avoid taking white's likely kingside attack head on; if not for the fact that doing so will cost you the g pawn with the queen on that file.  There is a defense here, but it's really tough to find.  9... Bxe3 10. fxe3 h5 11. h3 h4)  This ejects the queen from g3 with equality for both sides.

10. ... Be2.  I have a simple question, what was your goal here.  Yes this attacks the rook, but you will be attacked by that rook next turn, after which the only way to save your bishop will be to waste another turn playing Bh5, and still haven't solved any of your problems.  You were pretty much required to trade bishops and push the h pawn.

The rest doesn't deserve analysis, you just hung your pieces.  The basics are focus on developing your pieces, and make moves that have a reason behind them.  As an exercise look back at how many times you moved your queenside knight in the first ten moves.  I won't say that you should never move a piece multiple times in the opening (that's not true), but you should have a clear motive for doing so.  Active pieces are happy pieces, and the more happy pieces you have the better the position.

If you're fairly new this is going to be a big hard step.  You have to move past 3 ply calculation of every move you can think of and start looking at moves that DO something and using your time to calculate those deeper.

thanks for you're help everyone.  thanks to your tips i managed to ACTUALLY get an opponent to checkmate.  I found your help very helpfull.  here is THE game:

your opponent could play 7. ... Nf6 with advantage

But if he did not 50% of the time that would mean i could win half my games.  that is much better than how i was doing before
