I probably just min raise here and let them talk themselves into calling.

[Elrazor]

i think your raise is good, maybe a touch less. if hes slowplayed AAxx or caught R/R quads im just gonna pay him him here

[garcia1000]

I would make the case that against a good, thinking villian, calling is optimal, because the range of worse full house is around the same as better full house.

Against unknown, raise to $50 or so

I am raising to something between a min-raise and 55 here and puking if he shoves

I prefer the bigger end of it, 65-70. I think you get called almost as often and you are stacking off against better hands anyway.

garcia - BB hasn't exactly played his hand like a bigger full house or quads. But against a tight player I agree you might be getting no more value from a raise.
