Hello,
So at the time i was thinking :
- if he has weaker AA, AK, 2 pair, flush draw he will mostly call or sometimes jam
- if he has a straight he will mostly reraise not all in
- if he has a set he can flat / jam / reraise not all in

so that's why i folded, but then once i folded i couldn't stop thinking about the hand all day long and i started doubting my decision but his line does look so strong so i'm wondering was this a just get it in and was i being too nitty or is this fold ok.
