i think his ats is high enough to make it 3 bets preflop.
then bet flop, bet turn, free showdown if he just calls all the way
as played:
hm tricky. no wa/wb here imo. i think i would have raised a non diamond turn and fold to a 3-bet. you can fold this turn i think... the pot is just too small.
imho 
are you playing sh now on a regular basis ? i watched 3 hands today which have been played by you and they all were 6 handed.
if you do you should stick to the silver chart and maybe make small adjustments according to your opponent stats.
but i think in this spot it´s important to 3-bet preflop because there is a very good chance that you are ahead and most of the time you would be able to take down the pot without catching an A or something; simply by being aggressive.
3-bet preflop. There is no need to disguise your hand at this limit.
If he calls your flopbet you can think about a check/behind and a rivercall. That is he will fold most of his hand you have beat and will call only better ones but your hand is to good to fold but to bad to call.
If he chec/raises the flop you can fold the turn because he either had a better A or a fd.
Without 3-bet preflop:
Tough fold but what will a TAG bet here again?
