def. check those essays out. i can't even tell you what they have done for my game. i consider myself a tight/aggressive player, and think it works best for me. i can't remember in exactly which essay it is, but there is something to the effect that you don't want to be the one getting raised on, you want to be the one doing the raising. i keep that in mind every time i play. i want to be the one in control from the instant my cards are dealt to me. if you don't feel comfortable doing that, IMO, you should lay the hand down.
