am i being bluffed off the best hand or would this be a good fold?

pre looks fine, bigger is good too. Flop is fine, you could bet up to $0.25 though and get more value. Turn is too small (i like $0.48-$0.62) cos you're giving direct odds to any flush draws that called the flop plus you're telegraphing the strength of your hand. Fold vs the raise i guess cos KQ/TJ/slowplayed flop monsters/K9/etc. You aren't even a huge favourite against villain's bluffs/semibluffs

What daven said, almost no villains in the world you should go broke v here.

Agree w/ above
