I find myself not having the stones to call check-raises on the turn for fear of being Beluga'd, but I'm not sure if I'm being overly cautious. Here's a classic for me where I could go either way. The villain is 48/27/2.7. Don't have many notes on him except that he's played junk from all positions (obviously!) and plays both draws & sets aggressively.
