Sounds like you did it right. I struggle with this type of guy in MTTs a lot. One good spot you can look at is where you get down to about 15-20xBB and ship it all in over his late position raise (steal) with pretty much ATC, depending on how often he will fold to that action. Good spot to pick up not only the blinds, but his 3x raise. I love high suited connectors/gappers in this spot. KTs? sure JTs? even better.

Another move you can try if you're like 7xBB - 12xBB and you're not sure if you have reship fold equity ---try the stop N go. Works well with lower Ax hands and smaller pairs. Just flat call out of the blinds and shove any flop.
