If you want to be good at poker you obviously have to consider all parts of a poker game. You have to consider the position, blinds size, pot sizes, limit, players playing style, chip stacks of others and not only you, and other things. Poker has so many factors to consider each hand that it sometimes becomes overwhelming. Most players probably don't think about all of these while playing, but truthfully I watch everything everyhand. It's the only way I know how to play, all in or fold (not the stupid game all in or fold like on
pokerstars play money).
