So if he has the STP, you lose no matter what. If he doesn't, you win no matter what. I don't see how it matters what order you do things in.
If he has StP, I'd like to get as much life as possible--even though it would be difficult to win from then on, it wouldn't be impossible.
For instance, let's say my opponent has StP, I cast Berserk, respond to that by feeding my whole hand/GY to Tog, pass priority, my opponent StPs, I end up gaining 1 life, but have no Tog and on hand/GY. But if I pump Tog, pass priority, etc., etc., I'd end up gaining more life.
In general, though, I'm wondering what the are the 'good habits' of Tog players--facing an uncertain situation, what are most Tog players likely to do. I hope that clarified my question.
