Sam Loyd, pioneer of an interesting endgame It is well known that the knight is a piece that cannot win/lose a tempo. The position you see on the board was a study by the great Samuel Loyd, published in 1860. Can you imagine what White (to play) must do to draw? The same theme appeared in a number of subsequent studies, and the very interesting ending of knight and rook pawn vs. bishop, has been analysed over the years. In this series GM Eftratios Grivas tells us how it all developed.
