yeah 37/8 probably means you are limping in with a lot of smaller pairs, suited one, two, and three gap connectors, any ace, and small broadway cards and only raising your bigger broadways and big pairs. sound about right?

also you should be playing considerably fewer hands in early position (closer to the blinds) and more hands in late position (closer to the button). for instance a hand like A8s which is an easy fold from UTG might be a raise from the button.
