{There are 3 candidates moves : push the "a" pawn, push the "g" pawn or
activate the white King. None of them is good, but you must make a "silly"
move, a check ("weak players see a check, make a check !") and afterwards,
according to the place the black King went, all the candidates moves now occur.
The white plan is to force the black Bishop to sacrifice for a pawn, but he
must take care that the c2 square (that his own Bishop must control) is on the
same diagonal than his remaining pawn, because the WB must not be deflected by
