people who say call are wrong. Not much value in set mining against decent reg raising in CO because his range is huge you wont hit your set and have him have a stackable hand enough
whereas if you 3bet you can pick up the pot often right there and if he calls you have much better chances of winning his stack if you hit a set because him raising a cbet commits him assuming you re playing 100BB stacks

So why not check raise flops you miss? If his range is soo big he can't continue on a big % of flops can he? Also you don't have to fold every time you don't hit a set and don't want to bluff...
