5/10 in BB with top set on 3 of 1 suite flop

[Timonson]

Hi, I have seen a lot of very good players posting here and would like to participate in this community. I am a HU-"specialist" but I am working very hard to improve my 6m-game. I think my biggest leak in 6m is that I overplay my hands/bet too thin. In this hand villian is 16/13 and 1raises on the BU 27% after 1,1k hands. He is in particular a FR winning player but has a good winrate in 6m games as well. I donked the flop for obv reasons with the intention of bet/calling if get raised. I donk some flops with different types of hands but I am not sure if villian has noticed it. I think the most players do raise their flushes on the flop or on the turn so that I expected to be ahead if nobody raises almost always but I am not sure about that. What do u guys think about my play and thoughts here? Do I overrep/overplay my hand again on the flop and turn? What do you think is the best line with this hand overall? What would you do on the river as played: betsizing etc? Thx!

edit: SB is a 63/1 fish after 170 hands...
