A win...ok...I just cashed...

It's been a long time, and I don't know why, but I finally cashed in an 18 person sng. It's been a couple of months, but they have just been the kiss of death for me. I can cash in a 90 or an 9 just fine, but the 18's have been a pain. Tonight I finally finished in the money and landed a 3rd. Not what I had hoped for. I was even in with the best hand when the money went in and lost to the ever popular 6 outer...If anyone knows how to play this with a better outcome, let me know!
