All sorts of strange things can happen in a frame of snooker and this is what makes the game so fascinating.
Two examples from the Championship League today, each involving Graeme Dott:
He needed to win one frame in his last match against Steve Davis to reach the semi-finals. He missed frame ball red in the opener with six reds remaining and Davis set about clearing up.
Eventually, Steve finished dead straight on the pink and attempted to screw the cue ball off the side cushion for the black. In doing so, he horribly - and I mean horribly - miscued but the pink somehow ran around the table and found the yellow pocket. Worse still for Graeme, Steve finished perfect on the black.
That was 1-0, Davis won the next as well and things got very tense until Dott put away the third.
The other incident came in his semi-final against Judd Trump.
He potted a red and finished touching the green so played a roll up behind the brown.
However, he nominated brown for some reason - instead of the green - and failed to reach, thus leaving a free ball.
It showed that, out there in the arena, all sorts of things cloud a player's mind.
As I type this, Trump and Ricky Walden have made a quick start to the final. Ricky made it through after potting a terrific long black to make it 2-2 with Davis before winning the decider.
Don't forget, the winners' group starts tomorrow with a place in the Premier League beckoning for one player at the end of it all.
