Endgame theory (Queen vs pawn): If you have a queen and a distant king against a pawn thats threatening to promote, your strategy is pretty straight forward: You give an endless amout of checks until your queen forces the king to step in front of its own pawn. In this moment, you have time to advance your king towards the pawn. Rinse and repeat, until queen and pawn finally team up to gobble up the peasant (Fig1) However, Bishop pawns (Fig2) have their own rules. In the same situation (distant king+ Pawn on the 7th rank) the game is drawn. Why does our strategy not work here?
