[ErikM 0]

Does anyone know if there is a difference between the following two books by Cloutier and McEvoy:Championship No Limit & Pot Limit Hold em (Championship series)Championship No Limit & Pot Limit Hold em: On the Road to the WSOP.Is one of them just an earlier print or are they actually two different books?And if they are different... is it worth buying both or do they contain pretty much the same stuff?If anyone can clarify that for me it would be helpful! Thanks
