3...a6 is really passive, Nc6 is what I would suggest. 9...b5 (ASK yourself what your trying to acomplish in the postion. b5 is ok with Bg7 and Nd7 and possibly Qc2 and Rc1 and some point) instead of b5 I would might have played Be3 or even Nc6 (however in many sicilian lines the Queen's Knight is better suited on d7). 14...h3 is unwise to ruin your castled pawn structure (unless h3 is attacking a piece such as a Knight or Bishop if the position warrents it). I would have tried to get d4 in early trying to open up the center with his King uncastled. I wasn't really to fond of the Bishop sack, I would have liked to seen it swung back to d3 on move 27...Bd3 (attacking his Queen). After move 27 his attack is haulted, you should have ben striving for your own attack on the Queenside where you enjoy a space advantage, I'm looking at Qb4 eying e3. White is really uncordinated. His Rooks are not working together, he has stacked pawns, his Queen isn't really doing much in the position and his King is in the center and exposed <-- easy target!!
General Principle: If the enemy King is in the center try to prevent him from castleing especially in open games. Even if it means sacrificing material, worst case you will make him suffer for a long time.
here's a game i played earlier..not a very good one, i blundered a few times, but i mainly would just like some feedback on whether I'm playing the sicilian correctly. I became really sick of e4 d4 so i decided to try it out. Any helpful comments on wrong/right moves would be appreciated!
