If player 1 has a four-card Seven, he's almost a 2:1 favorite. If he has a four-card Eight, he's still a nice favorite. If he's paired, obviously player 2 is a big favorite. I think on balance this is a fold for player 2 in a smallish pot such as you describe. He's looking at a 3 BB commitment. The only point at which he would be able to confidently bet his hand is sixth street, if it comes good to him and bad to the other guy, and this will only happen a smallish percentage of the time. And if player 1 is lucky enough to make a 75 on the river, just how much action does he want to put in?
