Hi again,
I'm not sure if you've read Ken Smith's article Improving Your Chess in which he says that if you want to improve you must play gambits. There is a caveat though. He advocates gambits only after you have a rock solid repetoire that you can play against anyone without fear (including Kasparov). I have played a lot of gambits and there are many games in which I'd really like to have had something a little more sound up my sleeve.
In the same article he outlines recommended reading/studying lists as well as repetoires by rating. I wouldn't advocate following this blindly but it may help you thrash out your options. You can find his article here:
