I've seen a lot of people with some pretty messed up thinking lately in BC about situations where you're playing against drawing hands, and I just figured I'd mention something to perhaps get at least a bit of discussion started on the topic.

Suppose in a 10nl hand you have A K out of position against A 3 on a board of K 9 6 5, the pot is 24bb and you both have 90bb behind.

Which is the better bet size here, 12bb or 30bb? Ignore the intermediate values and just consider these two. What do you think?
