Catalan Opening

Based on A nice study by GM Max Illingworth here: https://lichess.org/study/x75NW8ek

This is the Catalan opening, after the videos from hangingpawns

This Containes the open and the closed catalan

In dieser Studie arbeiten ich am dem Catalan Opening

This study describes a rather unknown Catalan version. The opening is pretty open, there's a lot of ways to attack. The opening should lead to maybe a advantage for black but a really nice position hard to defend. Only stockfish thinks black is slightly better, a human couldn't defend perfectly.

Entire white repertoire based on the Catalan.
