Same-coloured bishops

Endings with same-coloured bishops (both travelling on squares of one colour) differ fundamentally from opposite-coloured ones: an extra pawn wins far more often, because the bishops control the same squares and can be traded. White to move here, and the position is won (per the tablebases).

White has the king on c7, a pawn on d6 and the bishop on h5 against the king on f8 and the bishop on b5. The stronger side uses the extra pawn and the active king: the bishop supports its advance, and Black's attempts to blockade it are met.

The key difference from opposite-coloured bishops is that here a material edge genuinely works. So king activity, passed pawns and the fight for key squares all matter.

Drag a piece onto the board, or click a piece and then click the squares. The cross beside the pieces sweeps every piece of that colour off the board, and a single piece can be dragged off the edge.
