Been in the midst of a downswing so just making sure I'm getting the most out of this pot. I didn't 3bet flop because it lets a lot of hands that may want to see where they're at get away, and with no flushes to worry about I don't need to tax anything. Turn blanked so I checked hoping to CRAI since not much changed. River was a great card so I made a standard half pot value bet, and any Q likely raises and pays me off.

Thoughts?
