I thought it'd be more interesting to leave out my hand and just ask what would be the worst pocket pair that you need to call these bets (if at all for #1).

1- villain's 40/10 after 150 hands, but no other reads. The button is basically a calling station. I've been slag.

#2- I haven't played this guy in a few weeks or so, but last time he seemed like a donkish lag (not a very reliable read though). I'm new to the table.
