There's a raging debate in another website about this.
I do not consider this an upset, because I usually base my picks on their current form, especially the way Carlo Biado has been tearing up the pool scene this year, and not on past credentials.
To win in 9 or 10 ball you have to have three things:
1. Good racked balls (A friend of the racker)
2. Accurate consistent power break
3. Luck. (call it what ever, GOD's power, randomness, your day, in stroke..)
Biado has all 3, Ralf has luck only (in term of ball making and position i give Ralf an edge), therefore, it is not an upset, just like if he plays Efren, we know who is going to win... Take for example Nick the Greek, he plays good but no where near Biado, Lee Van, Dennis O, ..and many other pros, but luck prevailed a bit longer with him, than anyone expected, based on his 1st 9-0 match loss.
Carlo Biado better be wide awake and watch Thorten Homman sharking moves, i am sure his Piony buddies will help him out a bit in that arena.
