AA in the sb, rethinking my river line

[Eidal]

Raise preflop. Why didn't you?

Flop/turn = standard.

Call the river reraise -- if he produces a 4 thats life.

FYI, I would have raised the river also because the BB will struggle to put you on an overpair based on your pre-flop line... or he may just be donk betting for no good reason. I see this play a lot at the 2/4.
