KK postflop all in to quadruple up early in tourney

[HardGrind]

This is from a $2 tourney that I am in the middle of right now. I thought instead of going all in preflop a considerable reraise would narrow the playing feild a lil & I would still get action from at least 1 person which I did. After a safe flop I felt that I should put the pressure on & much to my surprise I got two callers (which made me quite concerned about the strength of my hand at that point).

I prob make it a little less pf, 400 at most but usually like 340-360. Otherwise fine.
