Villain is 23/23 with a 0% 3bet over 81 hands. Over those same number of hands I've raised 9% of hands so I've not been that active, in fact only really raising from the BTN. 

Given that villain looks pretty solid and this is his first 3b, can we assign him a very tight range like J+,AK? 

So, can we flat pre given we're playing quite deep (for MTTs anyway)? And on the flop do you call one street thinking we're ahead of AK or just look to hit a set and if we don't then just fold?
