NL 100 - AA not raising preflop

[smw1992]

I have had 4-5 hands the last couple of days where villains have had pocket AA and do not raise preflop. I am throwing away money in these situations and would appreciate any suggestions. Some will limp and call a raise and I just can't seem to put them on a hand. Comments welcome and appreciated, here is just 1 example but have more that are similar.

no read on this villain, he has only been at the table for 3 hands. With his mini raise I thought maybe trips but was not confident and talked myself in to him having AQ.
