Ivan is perfectly right. In his History of Chess, Murrays cites Mr Plowden,
who was British Consul in Abyssinia in 1868 and was saying about the
'Pheels or Bishop' (we write Fils) :
'This piece moves obliquely, like our Bishop, but can only move or cover
three squares, including its own; ...'
The SABA = ALFIL, definitely. Sorry. We got to call otherwise a 3 square
leaper.
