your odds of winning with a hand like 83o are really really low. the actual numbers for winning with it by the river are higher, but practically you need to flop 2 pair or 3 of a kind. the odds of flopping a reasonable hand are nearly double with a suited connector. that's not to mention, you're horribly out of position.

it is good to lower your standards a little bit and call with slightly worse hands in the but let's not go overboard, play hands with potential.
