Leaving the throne of one's own free will is not a widespread practice in our lands, and at all times. But to take a seat in the Grand Duchy of Lithuania could be one of the consent of the feudal lords, who formed the council or the Diet. In other words, the supreme power in the principality was elective. However, usually chose from the sons or close relatives of the previous owner.
In ordinary chess, the king's power does not require confirmation: the king is the king from the beginning to the end of the game, victory is guaranteed by his permanent and secure position. The Belarusian-Lithuanian game offers options: on the part of white and black figures - two contenders for power, a prince and a prince. Accordingly, the prince may voluntarily leave the chessboard, leaving the heir on the field. And the party will not end there.
Every unexpected, daring, bold move is a chance to upset the opponent's balance, coordinate his forces, move on to a decisive offensive and eventually win. Implementing an interesting combination, sometimes you need to make sacrifices, if they are, of course, justified. It is possible to sacrifice even the prince, understanding, however, that for it it is necessary to pay less loss of one course.
