What Vadym and Chris espouse is not an absence of thinking, but rather an absence of opinions
I agree with this, plus we try to avoid overanalysing of things, situations where trader attempts to figure out as much as possible. It often leads to unpleasant surprizes because market is changing all the time, even in shortest time frame. Eventually it all probably boils down to forming of opinion like you said.
As far as chess concerned... I am former semi-professional chess player, third prize on junior championship in USSR, 1979. Chess is really whole different ballgame, but I do see how chess skills could help in trading. Culture of thinking, discipline of thinking, focus, concentration, handling of tension, emotional control - those are common skills for both. Former Soviet grandmaster Lev Psahis (now Israel) told me couple years ago that many of former Russian chess players become traders after immigration... probably not an accident :) Or we have inherent abilities for this? (hiding... sorry, coulnd't resist :))
Thanks guys, great discussion, value your opinions very much.
