A downbeat Mark Allen labelled his own form as “depressing” after beating Jackson Page 6-4 in the first round of the UK Championship.
Allen sealed the win with an impressive clearance from the green, but managed a highest break of just 56 in a low-quality contest in York.
“It’s actually quite depressing to be honest, the way I’m playing at the minute,” the world number three told the BBC.
“It’s not much fun. I’m trying so hard and I just can’t play. I’ve always backed myself under pressure but there’s something technical that’s not right because I’m missing so many easy balls.
“It’s hard to take any positives out of that, other than the fact that I got six frames.
“I’ve been trying so hard the last few months and it’s really getting me down because things are really good at the minute in my life and snooker’s just awful. Absolutely awful.
“It is all confidence. I know that two or three months ago I was the number one player in the world but you’re only as good as your last result and I just feel like I’m not playing well enough right now.”
Ali Carter also advanced to the last 16 with victory over Ryan Day.
The former world championship finalist made breaks of 75 and 99 on his way to a 6-4 success.
'That is a great feeling'
Carter will face Jack Lisowski for a place in the quarter-finals after Lisowski fought back from 3-0 down to beat four-time world champion Mark Selby 6-4.
Lisowski scored just six points in the first three frames as Selby made breaks of 119, 59 and 136, but the left-hander turned the tide with contributions of 55, 63 and 100 to level the scores.
Selby took the seventh frame to edge back in front, but Lisowski won the next three to record one of the most impressive wins of his career.
"I feel great, Lisowski told WST. "It is an amazing result, especially the way Mark was playing. He is one of the greatest players ever, so to beat him when he is playing like that is fantastic. Everything clicked for me tonight. My safety was good and my scoring was good.
"That is a great feeling. It is what you practise for. I haven’t had a great last two seasons so to start getting some results like that is good. It slowly builds up and there I am beating Selby on the main stage. I’ve done this before and got too excited.
"It is Carter next and that is going to be a very tough game. I have to find a way of keeping this up."
On the other table, China’s Wu Yize battled to a 6-4 win over compatriot Si Jiahui despite making just two breaks over 50.
