Thanks for the quick reply.

My genius thinking at the time of Hand No.1 was that the villain had an overpair, so I was behind PF but I would stack him for 170BBs if I hit my 8 on the flop. Is this a call that nobody ever makes, especially considering we were playing HU? Much agreed about the turn - no way I shouldn't bet - but given my read as him holding an overpair I figured the chances of him drawing to a flush were slim and the small flop bet made me suspicious of AA (if my KK, QQ read was off).
