Re no 2. Something renton said in his ama was trying to play as many hands as possible if you can do so profitably. That's somewhat of a misquote, but the gist of it is the more hands you realise you can add into your bluffing and value ranges the better. Hence why I mentioned looking at lots of situations where you won't typically know how much equity you have and looking to see if in these typically lower equity situations how a little fold equity can turn a c/f into a c/r.

Take note of me completely fucking this theory up in my most recent bc thread.
