Straight on turn....do you play different?

[bubbahotep]

This was going to be my last hand of the evening. I get KTs so I have to play it. Maniac had raised and WAY overplayed the last two pots. No great reads on villain. He's pretty new to the table. Maybe 5-10 hands that he played half of.

Do you play any streets different? I figure I have to call the river. I was nearly positive I was beat. I hated calling 2 bets after all that action, but I couldnt bring myself to fold with the pot so big and the nut straight. Would you do the same or are you stronger willed?

I feel like I play out too many hands but was this one justified?
