<font color="#CC3333">SB bets $18.5</font>, Hero does what?

Villain here is a decent TAG, stats are 19/16/2.8. He is probably solid/ABC enough to not be reraising lighter than the situation calls for, but it's obviously a spot where good players can reraise fairly wide.

I called preflop because folding seemed incredibly weak and exploitable, yet 4betting totally unnecessary. But what do I do now? I suspect villain is cbetting damn near 100% of his reraised hands, so folding still seems kind of weak.

Is it okay/standard to call a flop bet and then fold if he fires again on the turn? If we call and he checks turn, should we be betting? Sorry if this is actually standard, but it's got me very confused. [img]/images/graemlins/confused.gif[/img]
