A5o

You can try and see how SB reacts.

This is an easy raise for value in position against Phil Ivey and Doyle Brunson.

I'd use stats only on close decisions. To use the stats you need to be able to do the math yourself. At least you need to memorize a few combinations, and then only use stats when you have a reliable sample and stats differ considerably from "standard". (It is a very boring way to play poker:()

Yes, this is a raise for me on BTN. We cannot get too tight here, we also need to make money on the long-run by attempting stealing blinds. Of course, if it doesn't work and you get re-raised then we need to think of another strategy and tighten our range first.

A5o is a standard open from SB.

Yup, this is standard open. Against guys who will fold way too much to steals, I'm opening pretty much any 2. You can see how SB reacts to this and if he starts defending, you can tighten up again.
