I call a lot. I look at it like this.
at 10nl if you make it .30, the make it .60. You have to call .30 to win potentially $10ish. Thats pretty good odds
. These guys are bad enough to stack off light like any over pair or good top pair etc so if you do flat with 56s and do flop a good hand you will more likely stack him. Also you quite frequently get a good price on the flop to see the turn. They like to slowplay their monsters a lot and jam it on the river etc.
Yes you wont spike a 2pr+ hand often but when you do you are probably going to get paid off more often. So even if you call his min raise 20 times (that would be .30*20=$6) and miss, if you get it the 21st time and stack him it will be worth it.
Also sometimes you get multiway because its so cheap therefore giving you more odds.
If stacks are short then probably fold. Not sure the exact math on it though.
Also id be more willing to call ip because we get the last bet in and are more likely to get stacks in if thats what we want.
Just make sure not to stack off with A9 on 932 or something. And dont be afraid to fold your weak made hands to a 2 barrel because he probably isnt bluffin and he probably has you beat.
