I have about $280, nothing major happening. Opponent is a semi-regular, plays 1-2 and 2-4. No big reads, haven't seen him get out of line. I've been raising frequently in LP, so he's not necessarily putting me on a big hand here.
I get

Flop:

Turn:
![The Six of Clubs [6c]](https://pofex.com/images/smilies/6c.gif)
River:

Should I:
1) check behind
2) bet small ($90 say)
3) pot it
Comments on other streets also welcome, especially if you think that I should have manipulated pot size in such a way that the river becomes easier to play.
