On the March 2011 FIDE list, Prié has an Elo rating of 2508, ranking 737th in the world and 26th in France.

As such, he was one of the trainers of Étienne Bacrot, Laurent Fressinet,[2] Maxime Vachier-Lagrave and Marie Sebag.

This opening addresses the problem of excessive theoretical preparation among high-level chess players by playing a sane but unusual system, which forces Black to think from the start of the game instead of reciting moves learnt by heart.

Prié reached that goal by successfully playing his opening against amateurs, but also against titled players.

The following game was played by Éric Prié against British grandmaster Glenn Flear in 2005, in Lattes.
