Tiger needs to get into as many tournaments as possible. His game is suffering, but he has to keep getting after it, or it will never get better. If he does not take this approach, which I don't think he will, he needs to slow down completely and take a break from golf until he can get his family issues in order.
In my opinion it looks as thought Woods is trying to force himself to do good in the major tournaments, but that won't happen without some practice. He needs to concentrate fully, or else step away.
Only Tiger knows what he will do, but if he keeps playing, he will start to win tournaments, because he's Tiger.
