Checking to coldcaller

[Roy6]

I don't have any read on the coldcaller.
BB is 45/15. He is too loose and peels a lot. But he can fold on big streets.

I think the flop check is standard. What about the flop call? I thought I might get a honest answer from CO on the turn if both of us call (=he might check behind AQ), so thatswhy the peel without enough odds.

Bonus question No1:
I was also thinking what flop would I have bet 3-handed or only with a coldcaller if I didn't hit a K/J.
Would you bet A [img]/images/graemlins/club.gif[/img] A [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/club.gif[/img] HU/3-handed for example?

Bonus Question No2:
list me your hands you raise preflop and bet this flop with this lineup?
