AK pf and deep against stations

[registrar]

£20 (~$40) Crypto (midnight British time)

So, to quote Hellmuth commenting on the ME final table, it's amateur hour.

I find this spot trickier than probably anything else in MTTs. You pick up AK at a table full of stations who like their cards.

Standard is to raise and then bet/shove the flop but, often, everyone calls pf and then with any piece of the flop so is this still the most profitable play?

What's the best line?
