When I did martial arts I could spar with other experienced fighters and we could test each other and both learn a lot. We would be reading each other's moves and countering and trapping. If, however, I sparred with a novice I would usually get injured! Sound familiar.
I think to play poker you probably have to be playing at higher limits to try to avoid the novices of which there are probably more now than ever due to TV. Unfortunatley my bankroll just doesn't allow this. Maybe some of the more experienced ppl on here can confirm if this is true or not.
The analogy is a good one. (I was just wondering if the Yin Yang indicated a fellow martial artist) good fighters can feel each other out with out committing themselves until they're sure they have the upper hand.
Theres a guy in one of my home games who moves all in pre flop with any pair 2,2 to K,K and also with rag Aces. He's very difficult to play against because, taking the martial arts comparison, it's like an untrained fighter deciding to run at you wildly swinging their arms. yo know you have the goods but if you stand in front of them you just might get knocked out. so you have to decide whether to step aside and pick em off or stand your ground and hit 'em with your best shot. scarey.
