Hello, this hand was one of the first in the session so i did not know anything about other players. Was my play correct? Also this was a bring in but is it worth to call this hand, because 2 of my cards are higher then any door card and they are very lively?

You played this one about how I'd play it. As for whether to voluntarily put money into the pot on third, it depends. AK is a good starting hand in hold'em. You flop top pair about 1/3 of the time, and top pair/top kicker is frequently enough to win. In stud, you have to pay for your cards one at a time, and one- and two-pair hands don't hold up as often.

I might play this if the bring-in were half a bet so I was already half-in. I might limp in late if conditions were favorable, and that includes having opponents who let me have free cards when I want them. It is a trash hand, though.
