When you tunnel the fegundo across the room, you should remove as much briar as possible on your way.
×In a situation like this, if the fegundo keeps moving east, it removes 3 squares of briar for every square it progresses. (
f = fegundo just before exploding)

If, instead the fegundo moves northeast, then southeast, then northeast, then southeast, the fegundo removes 4-5 squares of briar for every square it progresses. This gives the briar more room to grow in, thus giving you more time to complete the room.
