Sorry if it's been asked before, but I couldn't find anything on it. In a $1/$2 NL cash game (probably $50 min-$400 max buy-ins, 8-max), would there be any use to having $2 chips? Would I be better off buying more $1s and $5s instead? If not, what sort of poker games would make better use of a $2 chip? $2-$40 spread limit perhaps?
