Pirc Defence Powerbook 2025

For the launch of the Pirc Powerbook 2025 a minimum rating of rating 2200 was set for computer games, 2000 for human games. 115 000 games from Mega and correspondence chess crossed this threshold, to which were added roughly 168 000 from the engine room of playchess.com, making a total of 283 000 games. The Pirc Defence is considered risky from Black’s point of view, because the centre is conceded to White. On the other hand, that creates for Black a chance, because just like, e.g., in the Grünfeld Defence he can attack the white centre. Thus the Pirc Defence is well suited to playing for a win with the black pieces.
