Here is a $400nl hand that I just played:

Positions and stacks:
Preflop raiser: button, ~$300
Big Stack: EP ~$700
Me: MP ~$400

preflop (hand: 44):
BB calls blinds
Big stack calls blinds
I call blinds
Preflop Raiser raises to $24
BB calls
Big Stack calls
I call

flop (pot $101, 4 players, board: 478 rainbow):
BB checks
Big Stack checks
I check
Preflop Raiser Bets $24
BB folds
Big Stack calls
I raise to $76
Preflop Raiser calls
Big stack raises everyone all in ($299 for me to call)

Should I call here with bottom set? My read on the PFR is definately KK or AA.

Opinions? Thanks
