Arnolds poker formula
So I've read quite a few books, but one i missed, that i hear some praise of is Arnold Snyder poker formula, so i went to ebay and saw they have a poker foumula 2, as well.
Question: Do i need both, or is 2 a more up to date revision?
I ask this cause i read kill everyone, felt i may have missed something because i never read kill phil, and when i read it, felt i lost some hrs off my life, ill never get back. (loved kill everyone, major EV+)
