Northern Ireland Open semi-finals: Jones and Wilson advance on opponents' misses

Only a yellow remained on the table. Mark Williams led 4-1, the yellow sat in a routine position with nothing blocking it, and potting it would have given him the sixth frame and a 5-1 lead — two frames from the BetVictor Northern Ireland Open final. Williams missed. Fifteen minutes later Jak Jones had levelled at 4-4. Half an hour after that, Jones won 6-5 and took the final place.

On the other table, a different script running on the same mechanism. Sam Craigie led Kyren Wilson 5-4, potted the blue, and sent the cue ball in off behind it. A pure cue-ball control error, in the one frame he needed to reach the biggest final of his career. Wilson levelled at 5-5 and took the decider.

Two semi-finals, two identical 6-5 scorelines, both decided by the loser rather than the winner. These were semi-finals that were lost before they were won, and that is the clearest signal that the Belfast final will be far drier than its billing.

The format explains most of it. Home Nations semi-finals are best-of-11, first to six; the final is best-of-17, first to nine. Across the four Home Nations events this is the shortest semi-final format on the calendar, and short formats are machines for producing 6-5 scorelines. Every frame inside an eleven-frame match carries far more weight than a frame inside the thirty-five-frame World Championship format, so one miss in frame six is worth three misses at Sheffield. Both semi-finals were the direct product of that arithmetic.

The prize structure makes the arithmetic harsher. Home Nations events weight the money steeply towards the closing rounds — the champion's cheque typically sits in the 80,000 to 100,000 pound band, the total fund between 400,000 and 550,000 pounds, and the gap between losing a semi-final and winning one is enough to move a season-end ranking. The promoter published no specific figure in the post-semi-final release, so I am working from the usual bracket. The invisible contract only appears when you count numbers instead of listening to promises — and here the invisible number is the two-season rolling ranking list, the thing that decides who is still allowed on these tables next year.

The ranking table behind the semi-finals shows three distinct tiers. Jak Jones is world No. 22. Sam Craigie is No. 72. Kyren Wilson is not quoted in the report, but as reigning world champion he sits in the leading group. Mark Williams is not quoted either, and at 49 he remains the last active member of the class of 2026 near the top.

The technical layer is where it gets interesting.

Wilson made three visits of fifty or more: 54, 95 and 98. No centuries. The 95 and the 98 say more than a single miss does — they are the fingerprints of losing position just short of a hundred, usually on the final red-to-colour transition or when forced to work a red cluster near the cushion. A player who makes 98 and stops is not a player who missed a hard ball; he is a player who did ninety-eight percent of it right and got the last part wrong. Against an opponent who closes frames more cleanly in the final, that is a repeatable vulnerability.

The tactical layer of both matches is almost invisible in the published data. No safety statistics, no pot success rate, no average shot time. We know who won which frame; we do not know who won the battle of the cue ball. The report records only what the naked eye can see, and in this sport most of the match happens where the naked eye does not reach.

Jones went the other way. The report supplies not one scoring number for him — no break, no century, no pot percentage. What exists is a frame sequence: 1-4 down, level at 4-4, 4-5 down, then the last two frames. He wins by dragging the match down to a safety baseline, splitting each frame into short visits, and waiting for the other man to open a door. That is the profile of a grinder rather than a scorer, and it matches his Sheffield record, where he reached a thirty-five-frame final on accumulated attrition.

Craigie was the strangest figure of the night. He made a century of 100, added a 55, and produced a 56 clearance. Measured directly, Craigie scored better than Wilson. My three numbers once broke a transfer deal that had barely begun — and Craigie's three numbers, 100, 55 and 56, broke him instead, in the opposite direction: they prove that scoring quality does not convert into closing ability. A world No. 72, below the top-64 retention line, played his best match of the week at the exact moment it mattered and then pushed himself out of it with a basic cue-ball error.

Williams sits on the far side of the career curve. Three-time world champion, close to fifty, still reaching ranking semi-finals. The yellow at 4-1 is a ball he has potted tens of thousands of times. Missing it is not a technique problem but a concentration problem: a veteran ahead in a short match, on an evening moving faster than he wanted. I do not hunt news. I hunt the silence between two answers in an interview — and Williams's silence after that frame, sitting still on his chair with the towel across his knee, said more than anything he said afterwards.

Now the part the official story skips.

The convenient framing for the final is world champion against world No. 22. That frame is correct on the numbers and wrong on the structure. Both men are long-format players. Jones's career peak is a thirty-five-frame world final; Wilson's is the title in the same format, won 18-14 against Jones himself. A best-of-17 final sits between their comfort zone and the short-format lottery — long enough for Jones's attritional game to breathe, short enough for one slip to change the trophy.

The real gap is not in potting but in closing. Wilson has proved he can win the last frame of a world final. Jones has proved he can reach one. In a final those are not equivalent sentences, and ranking points do not measure the difference.

The head-to-head sample is a single match, but it is the highest-stakes meeting the sport offers: a best-of-35 world final, Wilson 18-14. One match does not settle who is better. It settles who has stood upright at the final frame of the longest format.

For Craigie, the top-64 line is a real cliff edge. The arena empties, the money still flows, and the retention threshold turns out to be an umbrella for the stubborn — stubborn enough to keep playing after every near miss. The media shorthand calls him the Newcastle underdog; that label sells headlines and hides a career-conversion problem several seasons old.

Wilson arrives in the final on a warning rather than a statement. He led a world No. 72 by 3-1, went 3-5 down, and rescued himself in the decider. A reigning world champion pushed to the last frame by a man outside the top 64 is a form line pointing down, not up.

What matters in Belfast is not who lifts the trophy. What matters is whether Jones can take a frame in a single visit. If every frame has to be split into four safety exchanges, the final will be long, ugly and hard to read — exactly the kind of match where one missed ball in frame eleven decides everything. If he can take frames in one visit, the No. 22 story ends that same night. And if both men carry this week's century drought into the final, the Northern Ireland Open will be decided by whichever of them misses fewer times on a single ball.
