3-6 no fun deep AA spot

[FatalError]

6 handed
utg(650)
sb(1200)
hero(1400)

utg raise to 21, sb calls, i raise to 101 w/ red AA
utg folds, sb calls again

SB is a decent player capable of moves, but i think this is a set mine here

Flop 974 all spades
sb checks i check for pot control (standard?)

turn 2x
sb bets 120 into 225ish

whats the plan from here on out
