1010 short stack, but not desperate, should have pushed preflop?

[ZeroMan]

this hand from a stars $10 +1 tourney, i have a short stack of about 1800 (ave ~5K)with blinds 75/150 and have just doubled up with AA the previous hand. the next hand i get 1010 on the button with one limper in front of me. i decide not to push but standard raise to 3bb, the blinds fold and the limper calls.

the flop comes 7 J 7

the limper checks to me, to which i bet 3bb leaveing me with a stack of a bit more than 700, he check raises me allin and i call figureing hes trying to push me around and can have unpaired high cards. i insta call the raise and he shows KJ. i dont think i played this hand well, and think i should have just pushed preflop since i was not gonna lay it down, do you think that is the best play?

also do you aggree with my critisism that i gave the player too much credit for actually being able to check raise bluff me? in his position i would do the same with a made hand, so i know i made a mistake by calling.

generally what is the cutoff stack size for pushing preflop with a hand like 1010 and in the position described above instead of a standard raise?
