Button is the typical donkey at this level. I've noticed they like to bet when it's checked to them in last position.

I think I'd prefer checkraising here if I'm going to bluff.

i dont like it. the chances of him having a pair or a draw are very high given the number of people that saw that flop. he wont fold either of those to your turn bet (especialy since you called him a donkey). i dont even think check raising is worth it unless you are positive fold a pair of 7s there, since he obviously wont fold a 10 or a flush draw
