$11's - 99 pocket pair... over pair to flop

[Dr_Jeckyl_00]

I think I play pocket pairs wrong when the flop is all under cards to my pocket pair. How should I play these type of flops? Please be specific (i.e. not good to push b/c I am in early position, or if raised preflop I should bet 3xbb to see where I stand, or I should always bet 3xbb to see where I stand... someone could have flopped set, have a higher over pair, if board is coordinated always check...) Thanks

I would've bet the pot on the flop... but I'm not exactly sure if I could let it go unless Villain 1 raised, and villain 2 re-raised.

Without hitting a set, I never go all-in on this flop, or any other flop with 99 anyway.

I raise the flop approximately pot size, and fold to a big reraise or call + draw hitting. I try not to play for a big pot in these spots. The pot is so small, don't raise all-in, it's terrible.

The allin is silly. It's ten times the pot. You're either going to win a little or lose a lot.
