Reads: <font color="blue">villain was playing 35/25/oo over 40 odd hands. i havnt got any reads on how hes playing post flop, ive just noticed hes been raising/calling pfrs a lot. 1st hand i saw - someone minraised, then there was a min 3bet, he min 4bet to $2 then folded to a 35bb shove.. so he doesnt seem like the best player in the world.</font>

is it fine to be 3betting 99 here since i have position and 99 is def ahead of his raising range, + he prolly calls with all sorts of broadway. or would just calling pf be better?

should i always be cbetting here? for protection and cos i prolly have the best hand. once he raises i need to decide if i wanna play for stacks... dont really fancy putting in 200bbs with a marginal overpair w/o a good read so i folded.
