My thinking on the flop was to keep at least the over pairs in and try and maximise this flop. I agree that I should have bet a little more but was worried that might look like a flopped two pair and therefore would not get action. On the turn raise by villain I put squarley on A5 possibly suited.

I pushed, MP1 folded and villain called showing J 5o - not sure what he was doing in the hand in the first place frankly.
