What do you think?

Recently playing in my regular NL game, $5-5 blinds buy in 1-300. I am sitting on about 500 and in the SB and look down at KQ. A friend sitting at the other end of the table makes it $30 to go and i fling in a call. I check dark and we see a flop of Q Q 2. My friend moves in for about 250 and I beat him into the pot. He shows KK and I take it down. This sparked a debate about how "lucky" I was (on that hand no denying it) and it made my friend upset because of how I played it (checking dark.) Everyone at the table, me included, told him that moving in there would only get him called down by hands that beat him. Sure KK losing to KQ is a rotten beat but why overbet the $65 pot with 250 when you'll only get called by trips or a full house? Am I right here?
