I initially though that a push would be out of the question and calling made sense. Then I thought some more.

1300 in pot now, which is over 1/3 your stack.
Calling would be over 10% of your stack, which you would then have to fold on most flops.

Unless they were slowplaying a big pair and planning on a reraise, both limpers should fold to a push.

Would the big stack fold?
Probably yes, as he's not going to call off almost half his remaining chips without a really strong hand.
If not, then you can still outflop him.

So my initial gut reaction was way too weak/passive.

1) Push
2) Fold
3) Call

......in that order, with Calling being way worse than Pushing or Folding.
