good or bad move?

this is my first post, so go easy on me. i was recently in a tournament were the table i was placed was the tightest i have experienced thus far. the satck we start with is 600 units. up to this point everyone at the table would fold with even the smallest bet(i raised twenty five pre-flop with cowboys when the bb was fifteen and everyone folded ) anyway i am in middle position and i am dealt big slick. i just called 50bb thinking that the button would raise. he did not. six players. flop comes 2c Kh 6s. four players check to me and there is one player left to act after me. i go all in trying to steal and maybe get a caller with the king. the bb calls he is holding k6 off. did i even come close to making a good move or was i way off. sidenote: at this point in the tourney i have succesfully survived phase 1 of the tourny and the blinds are 50-100 so my thinking was make a couple moves to get some more chips. thank you for your input.

First: If it's the tightest tourny, don't even call expecting someone else to raise. Just bump it up yourself.

Flop play is wierd. Were the stacks tiny compared to the blinds? If so, then it's fine. If not, given the tight play you should be able to toss out 125 and take it.
