just some questions about situations I've gotten into where I don't know what to do:

1. Say there's 3-4 people in the pot including myself, I have a pp and flop bottom set on a suited board (neither of my cards match the suit). Do I have to check/fold here? Would a pf raise effect my decision here?

2. I raise 5xBB pf with KK and get 1 caller, someone else comes over the top, do I have to assume he has AA and fold?

3. Is there ever a time where I should bet/call/raise on the flop with anything less than top pair?

4. Say I have A9s (or any Axs with an avg kicker) and the flop is something like AK4. How do I react to a pot-sized bet...I assume he doesn't have AK or KK without a pf raise but is my kicker good enough to call or should I just save money and fold. Oh yeah, assuming I completely missed my flush draw.
