Giulio Cesare Polerio

Giulio Cesare Polerio (c. 1555,[1] – c. 1610; reconstruction of places and dates by Adriano Chicco[2][3][4]) was an Italian chess theoretician and player.

Polerio wrote a number of codexes in which a lively international chess dialogue is described involving the exchange of ideas among players in Italy, Portugal, and Spain.

A relevant part of the work of Van der Linde was to compare Codexes of Polerio and Gioacchino Greco even superfine.

Dd1-f3: e cosi ancor che habbia perso un pezzo resta con buonissima postura di poter uencere il gioco sapendo guidarlo à presso, il che sarebbe superfluo inogni modo se si uolesse mostrare la fine di tutti giochi, e per questo basta insino à un certo che, tanto che si conosca apartemente il uantagio del gioco, si come per la postura di dette giochi ogni giudicioso giocatore lo potrà facilmente cognoscere.

2, of the 1821 edition of A New Treatise of the Game of Chess the term Muzio Gambit was coined by Jacob Henry Sarratt.

Thus, Antonius van der Linde, changed the view on the historical development of the move order 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.Bc4 g4 5.0-0 in 1874, most notably in the last editions of the Handbuch.

Such a terminology is both in honour of Giulio Cesare Polerio and partially misleading since the major body of the theory of this opening was generated in the time span in-between 1821 and 1874.

The number of games played by Adolf Anderssen, Paul Morphy, and Wilhelm Steinitz[25] with 1.e4 e5 2.f4 exf4 3.Nf3 g5 4.Bc4 g4 5.0-0 or 5.d4 in the time span 1821–1874 was already rather high.

The rules for Chess opening nomenclature, and their historical development, should be taken into account while assessing van der Linde's claim of 1874 "D. Polerio-Gambit".

This suggestion is based on the observation that "im Handbuch (1864, S.. 366, § 3)" this move order is called "das Gambit des Calabresen".
