Dynamic Chess (Chess4)

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

If positioned on a knight- or a rook file a pawn can jump like a knight to an empty square, east-north-east or west-north-west. A condition is that the pawn is blocked by an enemy pawn. Compared with standard chess, this means that a flank pawn is sometimes endowed with an extra jump move. Hence the flanks cannot easily be blocked, something which greatly enhances attacking play.

There are three different variants of dynamic pawns. The pawn is endowed with the extra jump move to an empty square (1) if blocked anywhere on the file (2) if blocked on the 4th rank onwards (3) if blocked on the enemy side. Note! The preset follows rule (1), but the players can agree to play according to (2) or (3). This preset begins with the standard position, but it can also be played with queen relocation (see link below). Arguably, this variant poses a challenge to Fide-chess for online play.


The flank pawn can make the oblique jump move to an empty square if blocked. In an alternative variant the pawn can only make this jump move if blocked on the enemy side. In this position, Black can make the corresponding jump to d4.


The following presets are automated, castling and 'en passant', too. Pieces can be moved by pointing and clicking. At promotion you will be asked which piece you prefer.
