You've gone for a pot sweetening raise pf, one that will inflate the pot rather than thinning the field. With Ak I would rather get it heads up in position and in control. With the 2 callers in front I would raise to $0.30 or so. Hopefuly you are then against 1 opp and can c-bet with more confidence. As played I think c-betting 3 opps consistently will be a losing play. I would take the free card although others might disagree. Spiking the ace I would bet the turn and the river as well. The problem with passive opps is they don't tell you you're beat, so all you can do is bet your good hands when it seems likely you are ahead. TPTK is worth betting on this board I think. But hey I'm no expert
