1/3 NL Live Cash Game, Non-Casino

[BusterFlush]

We have a roving 1-3 Blind NL cash game every Thursday night in our town. All the players are businessmen and a professional dealer is employed (the game is raked).
Please provide your thoughts on this hand:
UTG player(LAG), hesitates and ponders and opens for $25. MP calls, CO calls, and the button calls. SB has QQ and makes it $100. SB is a somewhat tight who's big raises are respected.
UTG, MP, Button all call. Flop is 5d-6s-7d. SB Leads for $175. UTG folds after tanking (had 10-10), MP pushes for 77 more and button calls for less than 175. SB crying calls for the 77. MP has 8c9c and CO has 2c4c. Board bricks and MP wins.
Did the SB not raise enough preflop or should he not raised at all? Should he have checked the flop? Or is this just a badbeat that is unavoidable?

He might have made it $150. But $100 isn't terrible. I suspect 78s wanted to come along no matter what the raise was.

Should he have checked the flop?

No.

Or is this just a badbeat that is unavoidable?

Well, it was certainly a cooler for an overpair like QQ. If stacks are 100bb, then once the pot gets so big preflop, I don't see QQ getting away from his hand post flop.

Post stack sizes next time.

Sounds like a tough game to beat (sb's preflop raise should have been larger, checking the flop with given stacks is awful)
