Another bloody heartbreaking loss for Jack (and his fans).
Allen didn't even play well. He was really struggling, but just had enough experience - and patience - to make every frame a lengthy grind so it was played on
his terms. That lengthy incident in the 4th frame really changed the whole tempo and balance of the match and Jack could never wrestle it back.
Credit to him for hanging in there more than the old days - and for that amazing clearance in the 8th frame! But that game, and the Williams SF in The Masters, highlight the matchplay and experience advantage those elite level players still have over him. He's slowly closing the gap, but it's still very much there.
