It would be interesting to get some advice here because I really feel like I spoiled a winning position and had to be careful not to loose in the end. My opponent really starting playing much better once he was worse but for me but once I starting thinking about a win things went wrong.

That was an interesting game. I think 8...Nh5 or 9...Nh5 were interesting tries for Black. And I agree that you had some advantage after 13...Be6. But you really should have castled. Opening up the position with your queen rook unavailable really made a difference. I'm guessing that you forgot about the possibility of Black challenging you for the h-file.

17...Nf6 was more challenging, and I think Black has a small advantage--but it's a lot easier to say this when it's not your king being attacked!

I think one of your problems in this game is that your opponent also played some good moves! It's a lot easier when they don't do that.

A draw was a fair result, but when I put this through my computer, it turns out both of you missed good opportunities towards the end. I take no credit for either of these lines

33...Nc1! (you can't play 34.Kxc1 Rh1#) the threat is some combination of Rhh1 and Nd3, and it looks difficult to meet.

36.Qb8 looks very strong, threatening a mating net with Ne5

Thx alot Paul, your advice is very much appreciated. You are right about the tactical opportunities near the end, I also engine checked it and was very surprised especially by Nc1! which is a move no <2000 player would ever see I think, it is simply too beautiful. If he would have found it I would have been happy to resign :).

Do you think it is problematic to exchange to black squared bisshop on g3 for the Nh5 in the beginning? I would think that the open h-line could generate some problems for black then. But probably black is at least equal anyway.

It is really a pity that I wasn't able to spot the mating net at the end. Don't know how I can improve my awareness there since in turn-based chess you defintely have plenty of time to calculate everything.

I'm not really fond of 8.Qc2 (?). OK, it kills the ...Bf5 plan, but you double along a diagonal solidly closed by the pawn on g6, and puts the queen on the c file which might be dangerous because Black's plan might be the minority attack that will include ...Rc8 and pressing the c3 pawn. 8.Nf3 looks better.

11...Nd7 ? doesn't give anything to Black on a positional point of view, and tactically puts the remaining bishop on a bad square. Better the minority attack with ...Rc8 or ...a6 (/\ ...b5). Seeing what follows, I would be tempted to rate it '??' ; but that's easy to say after !

14...h5 ? : "Avoid as long as you can moving your pawns when defending " (Steinitz). Black may allow White to play h5, with the idea that if hxg hxg he will oppose rooks on the h file (but of course, White will keep the pawn on h5 or push it !)

Your line on move 24 gets into a probable draw, but why sacrifice the queen ? if 24...Rxh7 ?? then 25.Rhxg3 ! picks the queen (no need to play Qxh7+ ?)

I fail to see what 28...Kf7 ???? achieves (Ok, it's not losing, but it's criminally planless). 28...b6 and I prefer Black, but it might be my personal taste (I prefer the two rooks to the queen generally speaking).

32...Ne2 doesn't look so strong to me. My choice is 32..Rh1+ 33.Ka2 Rhh2 and if White takes a6, Black takes b2 with terrible consequences.

The final position doesn't look drawish to me... But my choice of 38...Rxf3 might get in severe trouble after (paulgottlieb) 39.Qb8.

I think that because you opened up the position before your king was castled it was difficult to launch a decisive attack.

@Irontiger:

"Your line on move 24 gets into a probable draw, but why sacrifice the queen ? if 24...Rxh7 ?? then 25.Rhxg3 ! picks the queen (no need to play Qxh7+ ?)"

I think Qxh7+ is necessary since Rhxg3? gets into a nasty trick: Qxg3!! Rxg3? Rh1+, I was very upset when I noticed the treat to my backrank and somehow relieved that there was a way out with the queen taking on h7.

CORRECTION: Ugggh Qxg3 Rxg3+ is obviously check, I am an idiot!

With your other comments I do agree, they are very helpful, just this morning I analysed the game with an FM friend of mine and he pointed out that Qc2 was a rather weak move, only have 1 plan (preventing Bf5) which black probably didn't intend to play anyway.

@Blobby12: Yes not castling was probably a decisive error, since my attack slowed down since I had to play the moves anyway later on, while black was ready to meet everything actually giving me some backrank issues..
