processing information is "all there is to poker"

but watching your opponents and understanding their past actions and applying them to the current situation, i'm not sure i'd call that "math"

i've really got into reading the poker books and i've learned from harrington, sklansky, yao king, hellmuth etc. that you have to get into reading both players and situations to be a top player... and it's not easy...

the basic math of the actual situation (pot odds, implied odds etc. only get you so far, especially in no-limit tournaments , eventually you have to call whether your opponent has some reasonably unlikely hand that he's representing)..

intersting subject, but as i said, the more i read books the more i realize reading your opponent is absolutely essential and not easy.
