preflops fine, bet $3.5 on flop, then if that is done and your bet called either lead for $8 on turn or check to induce a bet (villain dependent, i.e. if hes not agro just keep betting). If you take the first line and are then called just shove the river as you only have a pot sized bet left. 2nd line i wouldnt recommend and id only use against aggresive/semi decent oppenents who arnt simply calling stations. If you take this line i really dont mind a pussy bet on turn or a check, and if he raises just flat and with the river bricking definitely check to induce a bluff as thats what his range is mainly made up of by this point. However as i mentioned previously id take that 2nd line rarely as its definitely not as optimal as the first.
