"It depends," is the only answer to your question that makes any sense.
I'm gonna lock this thread, because I think it leaves things too wide open and is going to spawn a ton of posts saying "you have to consider a, b or c" and a bunch of other posts where people answer your question as if there is one right answer without even realizing that what they think is right is based on 8658 unstated assumptions that they take for granted, but may not be true at other tables.
That said, I DO think the forum could benefit from having a detailed theory thread about raise sizing.
So how about this, OP: read one or two of our concept of the month threads, such as
this one, to get a feel for what they look like, and then take a crack at writing a detailed theory CotM on raise sizing. Say, any time by Sep. 1?
if you agree, we'll leave it stickied for at least a month, and it will generate a terrific discussion on an important subject.
Cool? If so, shoot me a PM.
