Even though his PfR range is ahead QJs, I saw him raising on the last hand with A6o and I had good odds because SB called. Even so I think I should have folded it, I was oop.
On the flop I decided to donkbet because I was oop and I was up against 2 opponents (I didnt want to check/call, he could 2nd barrel me and he'd create a big pot where I can be beat against KJ or AJ already. Check/raise is an option though, but TPGK isn't that strong to do it I guess). He raised me but on NL10 many players get offended by a donkbet and raise with air, but then again I think I should have folded it because I was oop...
On the turn he insists and he probably doesn't have air here, and whatever he got beats me, so I fold.
My main questions is whether I should have called or folded preflop, and is donkbetting that bad like the name says? I usually do it on 3way pot with TPGK or TPTK so I don't give a freecard if the initial raiser decides not to cbet and I can take the pot right there.
