Always in calldown mode

[Leader]

Lately I've basically taken to the strategy of almost never putting myself in spots where I could make a really bad fold or a really bad calldown. I feel like I might be taking it too far sometimes though and missing opportunities. For example from today,

Villain is 50/25 and bluffy

I raise 9[img]/images/graemlins/heart.gif[/img] 8[img]/images/graemlins/diamond.gif[/img] OTB. Villain 3-bets from the SB. BB folds. I call.

Flop 6[img]/images/graemlins/spade.gif[/img] 5[img]/images/graemlins/diamond.gif[/img] 5[img]/images/graemlins/spade.gif[/img]

Villain bets. I call.

Turn 9[img]/images/graemlins/diamond.gif[/img]

Villain bets. I call.

Should I be raising here and calling down a 3-bet?
