I think I made an obvious mistake here...
UTG is a competent TAG, no info on BB.
I'm on the button with what I thought was basically a dry top two, but now that I look back I had two back door flush draws... Guy I don't know donk bets full pot and TAG calls. I decide that there are too few turn cards that are good for me and I get it in fairly bad... Donk has top two and a gutter (QT98), TAG has a wrap (QJ85). I think I should just call here...? If that is the case, how should we play the turn? It was the 6 of clubs (so no possible flushes)... Let's say Donk bets pot and TAG calls again (so both are basically all-in). Do we fold a dry top two to a shove and a call?
