an AA hand, passively played (55)

[sledghammer]

Passively played AA. SB is solid player, on the not too aggressive side, it seemed at the time. Such an insanely way ahead way behind situation. i thought i played this correctly, but I considered checking the turn. that seems way too passive with AA, when ill get paid off by certain pocket pairs, that its almost criminal. should i have raised the river? comments appreciated very much.

edit: my image is reasonably solid, maybe on the aggressive side, but not by much
