Ok, twice today I got quads. Both times within an hour of each other. How would you bet these. Heres what I did. 50NL game 6 max.

Dog delt 55
cant remember the position but someone raised pot to $1 and I called it.
Flop 556
PF raiser checks, I check. No one esle in pot.
Turn 6
PF raiser checks, I check
River 10
PF raiser bets $2.5, I raise to $10, he folds. Maybe I should have just raised to $5. Anyhow there was no draws on the board except for trips, full house, two pair or quads.

Second hand
Dog delt 44
One raiser to me for $1, I call.
Flop comes A44
Raiser bets $1.5, I raise to $5, he folds.
Probably should have just called his raise and let him maybe build a hand. I jumped the gun without thinking it through I guess.

Anyhow, would anyone play these differently?
