A collection of notes written on betting slips by late snooker player Alex â€œHurricaneâ€ Higgins are expected to fetch Â£1,000 when they go under the hammer.
The scrawled notes were penned by the former champion the year before his death last July, a spokesman for Hansons Auctioneers said.
They were given to former journalist David O’Dornan who spent two days with Higgins in 2008.
O’Dornan said: â€œIt’s a bizarre range of notes which provide a fascinating insight into the mind of the troubled genius that was Alex Higgins.
â€œMost of them are on betting dockets, there is one on the racing page of a newspaper and another is on the back of a bar receipt.
â€œThey really tell a story and for the past couple of years I had preserved them safely in an envelope tucked away in a drawer â€“ they deserve to find a better home with a fan or a collector who’ll appreciate them more.â€
One of the notes reads: â€œWas always honest and tried my best. Feeling good or feeling bad, tried my best.â€
Another note reads: â€œ(I was) technically the very best, better than any chess grand master, and when I decided to attack I was also lethal, plus I invented all the delicate screw and stun shots playing on or around the black and pink.â€
Known for his fiery temperament and audacious skill with a cue, the Northern Irishman was credited with revolutionising the popularity of the sport.
He died in July last year after battling throat cancer for almost a decade.
Another note, on his health, reads: â€œfair to middling, battling on, doing things in moderationâ€.
Hansons Auctioneers manager Charles Hanson said the notes were â€œalmost like an epitaphâ€.
The notes, which have been given a guide price of Â£1,000 to Â£1,500, are expected to be sold by Hansons Auctioneers in Derby on Thursday.
