Opponent is an aggresive recreational. Given he's aggresive I didn't like the idea of a CB as he can raise me off my hand a reasonable amount.

Given he has a 33% fold to 3b (albeit small sample size) I felt he could have a lot of draws that wouldn't fold to a cbet either but once I c/r they may find it diffult to call and we have reasonable equity. Also given he's aggresive he'll probably bet this flop fairly wide as I'm giving up a lot when I check here. so I can extract the most from the air part of his range.

Once the A hits although I do block KQ he can have KQ, AT,AJ and he is probably less likely to be aggresive with draws given I've shown strength on the flop?

So should I fold the AK here? and What do you think the c/r in this spot with the plan of gamming the straight and any diamond on the turn?
