Schach-B

This page contains one or more presets for playing a game online with Game Courier, an online server for playing Chess variants by correspondence.

The only difference compared with Fide-chess is the opening setup, which has been selected from the array of opening positions in FischeRandom Chess. In Chess-B castling on the king side is performed by moving the king all the way to the g-file. Castling on the queen side is performed by simply moving the rook to the d-file.

FischeRandom Chess brings with it certain disadvantages. Certain positions are too advantageous to the white player. On the other hand, other opening positions won't allow white to develop an initiative. Comparatively, the Fide-chess position is ideal in this sense. But there is an interesting alternative: let's select a suitable position from FischeRandom Chess which satisfies the condition that the position is balanced, and still makes possible a slight initiative for white. I propose the following position: RNKQNBBR.

For example, after 1.e4 e5 2.Nd3 Nc6 3.f4 white can try and maintain an initiative. The following opening example also gives a slight advantage to white: 1.d4 d5 2.f3 Nf6 3.e4

The following preset makes a reasonably good validity check of moves, but rules are not fully enforced, so you must know the syntax for en passant and castling. To castle you simply type the two moves, separated by a semicolon. To capture by en passant you type, e.g. "P e5-f6; capture f5" (small piece-letters for black).
