One of Comins Mansfield’s most famous problems and a textbook
example of its theme. According to Brian Harley it was greatly
admired by Capablanca.
Solution: 1.Qf5 abandons the battery and threatens 2.Rd4.
The two leading variations, 1...Sb5 2.Sc5 and 1...Qd3 2.Sd4
combine half-pins with self-interference mates following selfblocks.
1...Se2 2.d3 is another half-pin, this time combined with unpin of
the mating pawn and interference with the f1 bishop, and a fourth
half-pin makes good use of the white queen, 1...Sxd5 2.Qxf1. The
remaining variations are 1...Qxb3 2.Bxb3, 1...Qxd2+ 2.Sxd2
and 1...eS any 2.Rc5.
David Friedgood: A marvellous Mansfield which contains a particularly
wonderful constructional coup. In the variation after 1...Sb5, the white
knight can only mate on c5
because four other squares that would do equally well are occupied by
fully functional white pieces!
