KJo not bad, KJs is better. Neither are great and neither is middle position. Playing those from there can get you in trouble.
If it's early in the tournament, you likely don't have enough of a read on the other players or a feel for your table yet. Making a move with a speculative hand that doesn't even include an Ace is a big risk.
You can play this hand from that table position occasionally although early in a MTT is not the best time. If you are going to play, might I suggest a little 3xBB raise to try to steal the blinds. If you get a caller and the flop is not a lock, be careful. If you hit a K or J you can be out kicked. If you get a straight or flush draw, you could still be drawing dead.
If you're feeling donkishly lucky and you just want to see the flop for some action, you could limp or min-raise. This is not recommended as several players would come along at that price and you really don't want to see a flop come here. Dangerous.
Best play is to fold. Nothing invested and nothing lost. Those better
hands will be there soon enough!
