I guess you need to look for players with more experience. ;)
haha if my players were any older they would be dead :D
But seriously, you probably lost because of the luck/random factor. Luck/random factor is about +/- 10 points leeway from my experience...
Yeah I guess unexpected things just happen some times. Though I was expecting to win the game by about 30 points so even with a 10 point swing of bad luck I thought I would win. Oh well, just a game :)
