Introducing Chess 121

This chess variant is my own creation.
I wanted to keep as close as possible to the classic game of chess.
We only modified very little the rules.
There is no castling.
Pawns only move two squares on the first move.
There are four promotion lines for each player, the last four lines in the enemy territory.
The first promotion line is reserved for the Knights, the second for the Bishops, the third for the Rooks, and the last one for the Queens (Captains).
If a Pawn does not promote straight away when reaching a promotion line, it will lose its turn. That same Pawn will have to advance to the next line before being eligible for promotion again.
That’s all about the rules.
Enjoy!
