To the thread originator: From the responses you've received, it is clear that this topic has been discussed before, probably multiple times. Since I am a newbie to this site, but not to competitive chess, I had a similar interest in the topic. I was able to find a relatively recent thread which discussed this topic. I hope the info in that thread answers your question.
