depends on the strategy of each player, aggressive players will open the MP, even the BIG. I advise you to study about Range of Call, and open Raise, when you have this in mind it is easy to play from the positions. I prefer to wait a little while to observe the table, but sometimes I go in the first hand and it's a cash game, I'll see the river to see if I build a big and good play for me. As I mentioned several of each player profile
For me, I feel it depends on the X. If we're talking AQ or AK, raising some would be the appropriate move from my point of view. Being first left of the BB and only calling with AQ or AK doesn't seem to be the right move.If X is less than 10, then chances are you're hand won't stand depending on the flop, of course.Regardless of the player's style, opening Ax at the beginning of the game is suicidal in my opinion. Even in position.

For me in any game, I may only play Ax when suited and also depending on the type players I'm playing against.
When x is -5 then it is advisable to play only at late position.
