not bad, but pretty simple 
Exploit the Failed Development

pretty cool sequence of moves, but i don't get why black didn't castle. i'm not very good, but it looks like black loses a piece no matter what happens.
Thanx for putting up this example SilverPanic...well, As per my analysis, I think after 1.Qa4? you could have survived somehow by losing just one or two pawns not one or two pieces! see how:
1.Qa4 Bb6 2.Bxc6 bxc6 (not Bd7?) 3.Qxc6+ Qd7 now if: a) 4.Qxa8 c6! with the threat of 5...O-O followed by 6...Ba6 or 6...Bd7, winning the Queen. I don't think white can do much about it:
(some variations included, please click on "moves list" button to see all of them).
The correct move though, in my opinion, is 1.b4! winning a piece. Please note that I did this analysis by mind only, no engines used. If you have an engine in hand, please redo it, perhaps you gonna find something wrong with mine...
Anyway, this proves that even strong players (like your oponent, 2250) can make mistakes...use them! do not blindly trust their analysis. I know i talked too much, I hope I helped...please comment.
hmm mehdipiero i have no idea what you are talking about lol
and i like this one because it exploits a pin on the king and putting pressure on a pinned knight
and i agree with emc black should castle out of that situation earler but who knows lol
First of all black went wrong earlier in the game as his title points out, he had played Bb4 and after c3 retreated to a5 instead of e7. The e7 retreat would have removed the Bg5 pin issues.
After Qa4 0-0 would have been the best but black still loses a piece after Bxc6.
mehdipiero:
I make plenty of mistakes but I don't think Qa4 was one of them 
It's inventive analysis but in the final position you give after 7Nxf2 0-0 white is a rook and a knight up, and after Qb8 is sitting very pretty so I don't get how this is better?? Q can escape either to d6 or down the b file depending on black's response.
In any case better for white is 1Qa4 Bb6 2Bxc6+ bxc6 3Qxc6+ Qd7 4Qxa8 c6 5Bxf6 and if 5..gxf6 then d5 and the Q escapes leaving white a rook up or if 5..0-0 then the sweet 6Be7 threatening mate on f8 if black tries to trap the Q. So black plays Qxe7 and the Q escapes by capturing on c6; again white is a rook up.
Interesting position...
p.s. no engine, so I'm open to correction.
p.p.s. No, I didn't analyse any of that at the time 
Thank you MM78, for your response. excuse me, but i still insist Qa4 is generally dubious. ok first, after 6...Nxf2 7.Rxf2 i stated 7...O-O intending Bb7 of Ba6, who said take with Bxf2+??, that's in the first place the reason for Ng4 manouver, to keep white's bishop from Be3 which can drive black's bishop away from blocking the b file.
then, you said 4.Qxa8 c6 5.Bxf6, IMO black has either:
5...O-O 6.Be7 (nice but not enough) Re8!
or even simpler:
5...gxf6 still 6...O-O & 7...Bb7 in hand.
Beacause of all these complications, I strongly prefer 1.b4 for white with a clear win.
OK, your turn now to think!
5...O-O 6.Be7 (nice but not enough) Re8!
I love the analysis guys! Really great back and forth... I keep being convinced by whoever spoke last! LOL. But, Medhipero,[EDIT *I think I've got an answer for Re8* [actually now that I look again... no I don't!... hmmm... I guess I am convinced yet again...
], (I think that is the critical line) but I'll wait to see how MM78 answers. ;)
I thought this was "ho-hum Black has chowdered the opening and loses a piece" but you fellows have exposed some rather interesting and sharp tactics. Be7! is wonderful.

In any case I prefer 5 Bxf6, let's look at that)
then, you said 4.Qxa8 c6 5.Bxf6, IMO black has either:
5...O-O 6.Be7 (nice but not enough) Re8! (MM78: enough imo :-) 7 Bxd6 and the Q is still not trapped since if 7..Bb7 8Nxe5! hitting your Q and both Q's will come off leaving white well ahead.)
or even simpler:
5...gxf6 still 6...O-O & 7...Bb7 in hand. (MM78: I already pointed out that in that case white plays 6 d5 meaning the Q escapes by capturing on c6 supported by the pawn on d5).
Beacause of all these complications, I strongly prefer 1.b4 for white with a clear win. (MM78: that's a fair point, but a win of a piece for a pawn in that position would be a long slog, I was happy and remain happy that white is winning, although I agree your defence gives white some chances to blow it and that I didn't see all that at the time but I remain convinced Qa4 is a better and quicker win than b4. What can I say, I like complications...
OK, your turn now to think! (MM78 I'd be happy to let you try to defend this position in game, either rated or unrated)

yes, my hat is off to Mehdi, much more interesting than the game continuation (sorry Silver Panic)
here's my stab at the continuation following MM78 and Medhipero
Oh I see how things grown! well, yes maybe there are no much hidden things left for Black. Afterall, white is winning...But this one definitely desereved a deep look. Thank you all for your attention.
I believe that black would have no way to trap the white queen. :) I think 8 Qa4 was the correct move for white. :)
14.Bxd6 f6 and I think the queen trap is on.

If 14 Bxd6 f6 then 15 dxe5 looks alright. :) If black tries 15...Bb7 or 15...Ba6 then white has 16 e6 or 16 Qxe8+. And white is still up material. :)

You think I didn't look at those lines? ;)
14. Bxd6 f6
15. de (...I agree Bb7? is no good, and I don't think 15...fe is any good either: 16. Qb8! Bg7 17.Nxe5 +-)
15... Kf7!? and it's complicated... black is starting to come alive and might even
have some attacking chances developing.
*Well... looking a bit longer Kf7!? doesn't solve black's problems does it?... -- at worst white can always sell out with QxR when needed and he's still got a winning material advantage.
JG27Pyth
You come up with some interesting tries. :) After 15...Kf7 white has 16 Nd4 (with Qxc6 as an escape). If black gets rid of the knight with 16...Bxd4 then 17 cxd4 Ba6 (the only way to trap the queen) 18 d5 (threatening e6+ forking the king and queen and giving Qxc6 another chance at an escape). :)
Here's one of my games. Can you find how to make something good of this game?
