5/10 NL Online 10 handed

I have 66 in the BB. 3 limpers to me, I check.

Pot: 45ish
Flop: 67Q, 2 hearts

Checked to LP (covers my 1k) who bets 50. Folded to me, I call which is not my usual line.

Pot: 150ish
Turn: 7

I check, he bets 50 again, I raise to 250, he pushes, I?

I was thinking I need to call this, but really I hate calling here. Having a 7 and a heart draw was impossible.

Again, what kind of hands do I beat? Especially what hands do I beat that don't raise preflop?
