CO is an awful player but he's passive postflop. BTN seems OK.
The massive flop bet threw me a bit as I'd never seen the CO make a move like this before. At the same time it was basically a dream flop for me and folding seemed pretty nitty. Only value combos he has are 33 and 22 since he raises his strong kings preflop.
At the same time though I'm almost certain this player won't play draws aggressively. I suppose in theory he could be betting out with some weak Kx, but I doubted he'd go for that sizing.
