Knight in the corner

11/11/2009 – "A knight on the rim is dim" - there is no aphorism which is known more widely to amateur players than this one. And although there are more than enough exceptions to this rule, the phrase naturally is also fully justified. All the more so when the case involves not just a knight on the edge of the board, but that rarely spotted example of the species: a knight in the corner. Recently, one such example caused Ivan Cheparinov all sorts of problems, when the sad-looking steed was corralled in the corner with the help of a bishop. GM Karsten Müller analyses the ending Cheparinov-Caruana for ChessBase Magazine Online.
