AA 30-60 river spew?

I like a check-call here. Bet call maybe second. Bet reraise is not a good idea---what are you hoping to accomplish by this? Do you honestly think the CO can raise with a worse hand than yours here? He could have anything from the likely flush to an unlikely full house but your reraise here is just donating money to his raggedy flush. Furthermore, the BB may have a flush and was trying to decide whether overcalls or another bet from you was worth more. The reraise is not a good idea.
