I have troubles with the concept of bet sizing.
Let's imagine we're playing a reg. If I bet 1/3 with hand like top pair weak kicker and pot with trip^s for example, I'm capping my range and vilain can exploit that. I mean betting small with my weaker value hand seems incredibly easy to counter for vilain. And balance my weaker value hand with some nuts would 1) leave my heavy value range weaker and 2) I don't have that many strong hand to compensate and I'll have to split my nuts. I think it's useless since my nuts will represent a very poor fraction of ma weaker value range (10% of nuts doesn't protect a range)
I fell like I'm missing something. Does anybody wants to share their opinion?
