With two callers pre, how is the pot at $65?
I understand pot geometry, size manipulation thereof well, but I'm not a sizing EXPERT. And my 2/5 experience is limited to a handful of sessions, although I've played lots of 1/2 and I have friends who tell me all about 2/5 sessions, and I'm book/forum educated.
That said, it all looks fine to me, although as iraisetoomuch said, $20 would be more on the side of standard sizing (Isn't it bull**** you can't make it $17???)
River seems like a pretty easy Jambo. It's just over 2/3 pot. That's standard. If you lost lolvariance. If they folded endlessly berate them as to why they are bad.
