I think the only way to discover new things is by experimenting. Through experimenting you might be able to discover your own way of play that most of your opponents will find difficult to beat.
But on the other hand, you should chose the forum on which to experiment from, in my view it is best to experiment on an unrated games which 'may be' played against a computer.
I find playing chess in my own kind of play most satisfying and fun.
is experimenting a good way of learning as i dont really think about opening moves as I have just started with playing online I am not sure whether I get burnt! Never mind I dont think it will hurt much (I hope)
