He had played several times against Giovanni Leonardo Di Bona in Italy and the two chess players were considered equal.
Then Paolo Boi and Giovanni Leonardo Di Bona won the strongest chess player of their time, the famous Spanish grandmaster Ruy Lopez, at the first known international Chess tournament in the court of Philip II of Spain at Madrid, in 1575.
As a result, they became the strongest chess players of the era and henceforth the two were called the "Light" and "Lustre" of the noble game.

The chess treatises created by Boi were not preserved.
A small number of his chess games have survived to our time, such as his party’s debut against the chess player Shovara, which gained fame, but only the first fourteen moves have survived.

He was the first who, without seeing the board, played three games at once, and at the same time conversed with other parties upon different topics.
In France, Catherine de Medici, who was also an adept at chess, showered favours upon him; and in Portugal he had the honour of having the King Don Sebastian for his adversary.
