A somewhat new trend in lower limits is players doing stuff like opening super wide in CO, BU, and SB. I 3-bet these players light very wide, because most of the time, they're holding trash. But that means I have to value 3-bet them wide, and I'm not sure how to balance it.

Let's say a guy opens 60% of buttons over 100 hands and folds to 3bets 50%, and 4bets 15%. What range do you think you should be 3bet/5betting for value with in the small blind? (100 big blind stacks, the player in big blind is passive and won't cold 4bet bluff almost ever).

What about a guy who opens 100% of buttons? 100% of small blinds?

Thanks.
