R23000 ($3000) live tournament in south africa

SB +-43000
BB (Hero) +-30000

SB is good thinking player with a few big final tables and decent results to his name. He has been pretty active in LP and I have 3-bet him twice already in position (i had AA and QQ - but he folded pre, i showed the AA). He thinks I play decent (i have a few big wins online on a local network and one big live final table). we dont really have much history prior to this tournament. I have just doubled up one rotation earlier when 88 beat AA aipf in a pretty standard spot.

Blinds 500/1000 (100 ante)
hero has A2o
sb completes, hero checks [pot is 2800]

flop 358r
sb checks, hero checks

turn 5 (full rainbow)
sb bets 2000, hero calls [pot is 6800]

river 4
sb checks, hero bets 5500

standard? Is the turn a raise/fold spot?
