A young student was thrown out of a €10,000 international chess tournament in Dublin amid allegations of cheating.
It is believed an associate was helping the player by using a computer to plan the most effective moves.
The event - with a top prize of €2,250 - took place recently in a south Dublin school over six days, with players of all ages from more than 20 countries and a prize fund of €10,000.
The player reportedly won a number of games against strong opposition, including an international master - the game's second-highest level of attainment.
Four of the player's five games were broadcast live, enabling viewers to follow them from home and abroad.
The top four contests were also broadcast in the main playing arena at the tournament. However, in round four where the player lost a game, it was broadcast in the theatre.
In this round, the live board for this game was shut off after a few hours' play.
Following this, it is understood the player moved his queen back and forth on alternative moves and then resigned the game a few moves later.
