somebody shut me the fark up.
Most chuck roast are cut on average of about 2" thick and the grain tends to run up and down when the roast is laying flat, so you must cut the roast up into it's separate sections then turn on their side to cut across the grain. That is why chuck roast are so conducive for pulling based on how the grain runs in short strands. So I recommend cooking until completely tender.
