Just wondering what open sizing's we should choose for our strategy in super loose live games. I play in 2 games regularly. 2/2 at the casino and a 2/3 home game. In both games if you open to 3x from early to mid position, the pot will very likely be multi way which is a issue as it's tougher to realise an edge in a multi way pot. Both games have large open sizes compared to online and there's a lot of limping in both

I had an ex pro recommend that I open to $15 in the 2/2 game. This is too get people heads up so I can maximise my edge. This means I can't open as many hands. In the 2/2 game this isn't so much of an issue as I can get away limping suited connectors and small pp's where I think it's +EV to do so without getting exploited. Where as in the home game I can't as the players play really well post flop.

So in the 2/2 game should I be limping some hands and opening to $15 with others? Or should I open to $8 and have a more balanced opening range and play more multi way pots?

The 2/3 game is a different beast as if I open to $20 I will still likely get multi way action. To what extent should I be looking to exploit this huge pre flop leak of theirs? I feel if I open to $12 rather than say $20-$25 I am missing out on exploiting such a huge leak and won't have an edge in the game as they play well post flop. But I also want to have a balanced range post flop as they play quite well post and I don't want them to exploit me

Note that having an edge is tough in my city as the casino have a monopoly on poker so the rake is huge. Rake in home games isn't as bad but it isn't great. So I will try to take every opportunity I can to maximise my edge.

Also wanted to know if this concept could generalise to different live games as there's some super fishy 10/20 and 25/50 home games I will be moving up towards that likely play different
