ok ill try to make it really simple

hand 1 ... fold preflop. you dont need to establish any kind of aggressive image, your opponents arent perceptive enough to understand this, you should just be furthering your understanding of fundamentals. u shouldnt be wasting your time doing this crap til you become a real master at it. it necessitates a strong fundamental background which u just dont have yet if you dont know what to do on this turn. particularly this deep.

hand 2 ... raise flop ... you picked up 2nd NFD, an overcard, and some backdoor straight draws. You called preflop cuz u were expecting him to steal ... why would u want to try to float w/ a hand that has so much equity on the flop? you want more money going in when your equity is good, in which case you can buy yourself a free river card, as well as build a pot in case you hit your hand, or give yourself the best opportunity to take down the pot. it sucks to miss your draw on the turn, then be faced w/ the decision to check behind or bet when u could get checkraised and be forced to fold, or just end up getting called down by a hand u coulda pushed out earlier. like i said, dont think too much, u have equity, so raise.

hand 3 ... call turn, call river .... your hand is soooo underepped. u may be behind more often than not, but if u play this hand so passively, u r opening yourself up to making huge mistakes in future hands against this player. im about to go to bed and im just not gonna try to get into why right now, send me an im tomorrow and i can explain.
