This was a hand that happened between a couple of my freinds and was wondering if it was played right by the button:

4 people playing, cash game, chips danm close to even, .25/.50 blinds

Button is dealt Ac 7d raises it to 1.50 before the flop ans is called by only the BB, a fairly tight/weak player.
Flop is: 4c, 5c, 6c, Button flopped OESD and the nut flush draw. BB bets 2.00 into a 4.50 pot and Button goes all in for 19.50 more (.50 less then BB) into a 6.50 pot.

This is where I think the mistake was, I would of raised/just called here in hopes of hitting my draw and getting more money out of it, and if missing the draw getting away without losing all my chips.

Well the BB called with Jc Jh (was this a bad call?), and both the turn and river card are blank, and Button loses all their chips.
What do you think?

I don't hate the move in. I prefer a raise to a call here anyway. The reason is because of the exact hand that the BB had. If the button calls and hits the straight, he probably won't get much action from an overpair because there is a 4-card straight on the board. If he hits the flush, he may not get action because there is a 4-card flush on the board. It just so happens that his opponent did have a club, but there is obviously no way for the BB to know that. It may have been a bit of an overbet, but I don't hate the move in right there. The button is a 3-2 favorite to win the hand at that point, so technically he had the best hand as well.

The BB's call was probably a bad one, but one I might make depending on my read of my opponent.
