Ronnie O'Sullivan has many loyal fans and they will be very disappointed by his early Crucible exit but the Betfred.com World Championship goes on and the rest of the field will now be fancying their chances.
I thought Mark Allen was sensational. He took the game to Ronnie and was fearless in attacking at every opportunity.
O'Sullivan seemed to feel the pressure, proving that anyone can crack in the heat of the Crucible.
Can Allen go all the way?
I'd say he can. He was used to winning before he even turned professional. Indeed, he won every conceivable title as an amateur - the Northern Ireland crown at all age levels and the world, European and European under 19 titles.
On his television debut at the 2005 Northern Ireland Trophy he beat Steve Davis 4-0 and then John Higgins 4-1.
He's fiercely determined and will be full of confidence after his defeat of O'Sullivan.
And he clearly has the game to put the fear of God into anyone left in the tournament.
