Simon Wilson started the nine-player final table of the 2025 Irish Open Main Event fifth in chips.
Michel Karim held the chip lead at the time.
By the end of the tournament in Dublin on April 21, Wilson had won the event. Karim finished fifth.
The change in positions shows why poker fans should look beyond the name at the top of a chip count.
A chip lead shows how many chips a player has. It does not predict the next hand or decide the final result.
Poker involves decisions with incomplete information. Players cannot see their opponents’ private cards, so they must interpret betting without knowing exactly what they face.
A bigger stack and a stronger hand are also different things.
The chip count shows a player’s available resources. Hidden cards leave part of the contest unknown.
Put the lead on a useful scale
Karim started the Irish Open final table with 51.2 million chips.
Wilson held 25.4 million.
Wilson therefore had just under half of Karim’s stack.
That comparison provides more context than simply saying Karim led and Wilson sat fifth. The numbers show the gap between the two players.
The blind level adds another important piece of information.
The big blind is a compulsory bet that players post before cards are dealt. Tournament organisers increase the blind level according to the event schedule.
Players can divide their chip total by the current big blind. This gives the stack size in big blinds.
The calculation puts a player’s chips into the context of the current game.
Players should always use the blind level recorded alongside the chip count. Using an earlier stack with a later blind level can produce a figure that never represented the player’s actual position.
Compare the players who can meet
Before the field reaches one table, the tournament leader and the leader at a particular table can be different people.
The overall standings describe the field; the nearby stacks describe the opponents a player can face immediately.
Within a hand between two players, the smaller stack limits how many chips they can match against each other. This is called the effective stack.
A larger stack cannot make an opponent contribute chips they do not have, and an unmatched excess bet is returned.
When the larger stack calls a shorter opponent’s all-in, it retains chips beyond the amount matched.
Losing that contest alone therefore does not eliminate the larger stack. It can still change the leaderboard substantially.
Wilson’s final three-player contest included double-ups for both Umberto Ruggeri and Ignotas Kirsis against him.
He still had chips remaining, later eliminated Kirsis and faced Ruggeri for the title in heads-up play.
With several players involved, further matched bets between players who still have chips form a side pot.
A player already all-in cannot win those additional contributions. Keeping the pots separate explains why winning a hand does not always mean collecting every chip being contested.
Read the field, not just its average
Average stack is the total chips in play divided by the number of remaining players. It provides a reference point, but it does not identify the middle-ranked player or show how closely the leaders are grouped.
A few very large stacks can leave many competitors below that average. If the total chips in circulation remain constant, eliminations also push the average upwards without requiring an individual player to gain chips.
The complete count is more informative: compare the leader’s margin, the chasing group and the shorter stacks. Then check how many players remain.
Leading an early field and leading the final two-player contest involve very different amounts of unfinished competition.
Why the lead does not settle the result
Describing a position and forecasting a result require different evidence. A 2025 Frontiers study of Bundesliga football tested its predictions against actual match results, checking accuracy and whether predicted probabilities matched observed outcomes.
In poker, chip share records the proportion of chips a player holds. Treating it as a winning probability requires evidence beyond that calculation.
A percentage of the chips is consequently not, by itself, an independently measured chance of winning. Turning the count into a forecast requires assumptions beyond the count.

Wilson’s Irish Open run shows why: fifth in chips was a position during the competition. First place was the result after it finished.
