Okay guys thank you for answering me.
:I don't usually make calls like this ,but in this situation he really made me to do it.He won the all-ins with cards like 5-10 of heards ,9-J,etc, so i tought he will have a crappy hand this time too.
@met3or:You are absolutely right,in the long run i will never get profit with calls like this one.But i was so frustrated that he took me every blind and couldn't even see a flop,i got kind of tilted and just clicked on "call".
@grafkarow:Yes there were some players to act,but they folded so it was just the two of us.
Anyways,i pretty understanded why it was a donk call.Next time i will think twice before risking my whole stack on cards like those.And when i will make the next thread i will post the hand history,to make you understand better the hand.
Thank you for helping me out.I'm still a poker amateur ,so i hope i will learn lot of things from here.
