Elkies | It's even true if instead White has an extra B or N (as long as it doesn't support Qh2+ . . .), or White has an extra B/N and Black has an extra Queen. Any other Black piece wouldn't do, because a mate could be constructed; even B vs. P or N vs. P is enough mating material because (if the P is not already on a- or h-file) it could underpromote to a Knight and smother the bK in the corner! Exception: K+B vs. K+B is a dead draw if the Bishops move on same-colored squares (this used to be noted explicitly in the rules). | |
