Imagine hiding in a cave thinking you are safe when a whole group of aholes corner and kill you. No thanks.

Yes, it is said that the morphlings won their games largely by hiding until the very end. It's a good idea in theory. The problem is that the game makers don't like it and they will interfere. That's why they starting throwing fire balls at Katniss in THG.

Foxface more or less did this, no ?

The Gamesmekers simply wouldn't allow it

It wasn't in the Quarter Quell, but I believe one or both of the morphlings won by hiding until everyone else was dead. Am I right?
Haymitch won the 2nd Quarter Quell by using the force field to his advantage.
I intend to live forever.
So far, so good.

Didn't one of the competitors in the Quarter Qwell win his tournament by hiding the whole time?

I wish that Rue had the same evasive tactic that her alter ego Young Cateleya had in Colombiana when those thugs that killed her parents begun chasing her. She ran for the hills and even hid in some kind of structure and under a manhole to get away from her parents' killers! Rue could have won The Hunger Games if she acted like Young Cateleya! Amandla played both Rue in The Hunger Games and Young Cateleya in Colombiana.

I wondered that myself, but the gamemakers would flush them out. It's part of it being a television show. After a while they would have gotten Rue out of the trees.

Rue persued a strategy similar to that. observe, evade, keep herself well fed and strong, and wait it out but not engage.
