QJ hits top pair on drawy board vs jalexand42

[goofyballer]

CO is jalexand42, running at about 23/20. I'm a nit (like 16/14) and we talk poker a lot so he knows this. We tend to stay out of each others' way at the tables.

Hero needs a plan

Just for fun, evaluate the best action in each of these two scenarios (as well as whether I should check or bet turn):

Turn: ($144) 2[img]/images/graemlins/club.gif[/img] (2 Players)
Hero checks, <font color="red">CO bets $110</font>, Hero...

Turn: ($144) 2[img]/images/graemlins/club.gif[/img] (2 Players)
<font color="red">Hero bets $110</font>, <font color="red">CO is all-in $424</font>

If I bet turn and he calls, or if I check-call turn, what's my river plan? I assume I'm checking pretty much any riv since I don't see myself getting called on a 3barrel with worse hands here and all I can really do is bluffcatch. So, I'm c/f any spade? What about 5/7/8/T/J/K since any of those complete a possible OESD or double gutter?
