should i have reraised on the flop? than turn? than river?
yep you definately should raise somewhere. your hand is huge and there are quite some draws out there. most likely he has a J or even worse. if you are not sure where to raise just raise the flop. you can even cap here.
in this special situation when you are ip and hu (after BB folded) you can just flat call the flop and raise the turn to get more value out of your hand.
if you were BB and there was a third player behind you on the flop you should raise the flop donk directly to let him pay the maximum.
there is a very important article in the silver section so try to get there
