Belarusian and Litvin chess (also known as Belarusian chess) is a kind of chess created in Belarus in 2010 by Aliaksandr Astrowski and Mikalaj Tamaszevicz. It is distributed in three versions: an online / desktop game, a gift set and a noble set.
The main differences of the game are the 81-square board (9x9), the presence of a throne and a palace. The seventh figure is a kniažyč, who, under certain conditions, can become a kniaź. The rest of the pieces are close to their counterparts in traditional chess, but are named after historical Belarusian military units.
The goal of the game is to seize the throne (square e5) and hold it for one move without declaring a rokosz.
