Preflop cold call could be a bigger ace, small pair, or some kind of suited connector.

I bet the turn as well. Fold to a raise.

The river - I probably check the river and hope for a free showdown.

The way I see it : You bet, get called you lose 1BB. He's not calling with anything you beat.

You bet, he raises, you fold. Lose 1BB.

You check he bets, you call. Lose 1BB.

You check, he checks behind: free showdown.

Slightly better chance if you check.
