What do you think of this move?

[DOTTT]

9 handed $1-$2 game. Utg+1 loose but decent player makes it $10 to go, mp+1 a very passive player calls, sb calls. I’m in the bb with ATc and call.

Flop comes: 6c 9h 9s

It gets checked around.

Turn is 9d.

Checked to utg+1 he bets $15, it’s folded to the sb who makes it $30, I raise to $75. Comments.
