well....every person is different...has a different approach, so I can't give you real advise which would be good for you....
Though....normally if we play a tournament we want to go for top finish.
But....normally we play tournaments, which fit our level and bankroll.
If I have a ticket for a tournament which is way out of my comfort zone...due to the high buy-in, meaning the money is very significant, I would play different.
You'll understand, by that I mean trying to at least mincash and go from there.
A bit like I would play a satelite....
Again....this is not advise....it's just how I would approach it..
Anyways....best of luck with the ticket.....
