With same-coloured bishops an extra pawn wins far more often than with opposite ones: the defending bishop cannot blockade the passer reliably, since both bishops travel on squares of the same colour and can be traded.
Here White has the king on a7, the bishop on f5 and an extra pawn on b6; Black has the king on a5 and the bishop on f3. White to move, and the position is won (per the tablebases): White escorts the b-pawn home, covering it with bishop and king.
The lesson: when judging bishop endings, look at the colour of the bishops first. With same-coloured ones an extra pawn usually decides; with opposite-coloured ones, often not.
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.
The pieces will be arranged into the chosen pattern.
It is the mating side to move. Find mate in one.
Openings, endgame positions and breakthrough studies - the set-up appears on the board.
Force the opponent's bishop off the diagonal of the queening square, bring the king up and put the opponent in zugzwang.
A position where any move the opponent makes worsens their position: the bishop has to leave the diagonal, or the king to step away from the pawn.
No. If the bishop has taken the right diagonal and the king blockades the pawn, the position is drawn.
