Playing AA against three blind hands

[BOTW]

Tight/passive table. Usually, there are three seeing the flop for two bets. A new player with a short stack just sat down (full table) next to me and posts.

I get AA in middle position.

Two folds and Tight-Passive (TP) calls, New Player (NP) checks, I raise, folded to the blinds who call, TP, NP call. Five to the flop for 5 big bets.

Flop: 5,6,9 rainbow

SB (tight passive) checks, BB (good player) bets, TP, NP call, I raise, SB cold calls, BB re-raises, TP folds, NP cold calls, I re-raise (cap), SB cold calls again, BB, NP call.

Four players to the turn for about 12 big bets.

Turn: 8 completes rainbow, board is 5,6,9,8

SB checks, BB bets, NP calls with a couple chips left, I fold(?), SB folds.

Two to the river for about 14 big bets:

River: A final board is 5,6,9,8,A

BB checks, NP goes all in, BB calls.
