Geez this is a tough spot at the lower limits because they could be pushing an Ace baby, esspecially since no raise preflop.

When I was playing 25nl there were times I would muck flopped trips and times I would go to the felt and it depended on villian. Stats/reads are important as Rocky said.

fwiw sb check/called flop and check/raised the turn, which is usually an indication of a big hand.
