Use Vitruvius the first chess engine that analyse like human.
Vitruvius is a chess engine complying to the UCI (Universal Chess Interface) standard. It may be installed on all major commercial programs such as Fritz©, Schredder©, Aquarium©, ChessBase©, Chess Assistant©, and free programs such as Arena, Scid Josè o Winboard.
Vitruvius is built on the skeleton structure of the free Ippolit programs (RobboLito, Igorrit, IvanHoe) from which it inherits certain caracteristics and pecularties. It is however a chess engine in its own right exhibiting a very original style of play with a highly speculative tendency. Thanks to its finely tuned positional vision, Vitruvius shows a readiness to sacrifice a pawn or two, the exchange and sometimes even a whole piece, for purely positional compensation.
Vitruvius’ goal is to promote powerful, human-like-play in order that players of all strengths and levels can benefit from its use in their preparation for their over the board engagements.
