[NL50 SH] Flopped a FH... check or bet?

[Feroc]

Not many reads about my opponent, more tight than loose.

UTG ($46.80)
MP ($56.85)
Button ($60.85)
Hero ($89.85)

Preflop: Hero is SB with , .
3 folds, Hero raises to $1.75, BB calls $1.

Flop: ($3.25) , , (2 players)
Hero checks...

I have posted this hand, the complete one, in another forum. We've discussed Turn and River play and I see my failurs there. But now we are still discussing the flop.

Some say:
It's too obvious if you check the flop, because normally you do a CB.

Well, that's true. About 90%+ I do a CB, but as I don't have any reads on the BB, the BB won't have any reads on me either.
Additional to that, we are playing NL50 here. So most of the guys don't care what I do anyway. They play their cards.

Now am I wrong with that? I think a CB will scare my opponent aways here...
