I also consider fold obvious against unknow. I would prodably c-bet little less but that the way I play. If BB are loose and seems to be someone that likes to make moves hard to say after 15 hands but if I see that he have played half or so of the hands so far and seems tricky I would check flop and then if he check again on turn I bet if he bet on turn I may bluff-raise him because not c-betting on this flop and raise turn it look like I have hit a set on flop and just checked to trap him because the board was dry, it will be hard for him to continue in the hand even If he get TP on turn but if he got a set on flop you feel stupid but thats not likely and this move can make a Villain fold many hands that have you beat. And if he was making a move on turn he will not try to make a move at you again and everybody will consider you tricky now and fear you and thats good.
