Was ready to check raise one caller

Again, sorry no exact hand history.
Early-mid tournie. I have about 1600 chips. BB is 100. No reads.
Dealt 89c BB. EP (2500 or so) raises to 200. LP (2000 or so) calls. I call. Flop comes 23c + 9. I check aiming to raise, possibly all in, depending on the action. EP raises to 400. LP calls.

It's a fold, right? (not that I did, i had fallen in love with the hand, wasn't paying full attention to the fact that there were two callers and donked it all in)

However, up to that point, should I have done anything differently?
