Salkkuman: Same rules as the ones used on FICS and ICC for those who know them : pawn is promoted, remains physically a pawn but assumes the power of the announced piece. When captured it reverts into a simple pawn. No pawn drops on 1st/8th rows. Drop-check and drop-mate allowed.
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
