I am sooo close.
I only play at work during breaks. I am always getting to the 7 or 8 level and losing it. If I can ever get about 8, I am going to abandon my stategy of playing at the highest level possible.
After playing awhile I realized the situations where I lost most often happened when a 6 or 5 was thrown 1st. After a lot of thought and experimenting, I decided that when a 6 is thrown, I will throw my 6 also(or sometimes a 5). I've noticed that most people do not like to throw a 6 on the first card, but don't like to throw a 1 either, so they end up throwing a 4 or 5 when the 6 shows up. This allows me to take a really big win right off the bat. Even though my opponent noow has a card advantage, it is generally worth it.
