Obv depends in my opinion on buy-in. Usually you shouldn`t expect to be behind vs a random donk.
What confuses me also is the size of the bet. Usually ppl donk smaller with a FD...
I`d really wanna scope him.
Think I`d still shove it in because its a donkament and i love doubling up early

. Obv this assumes that the buy-in is lower than 50$.
