To add a bit - fox is ferz, from even 'Middle Ages' shatranj-chess large
board fusions; the dog is still hunting the fox; don't want to rune this
one for anyone, but; and I have to disqualify myself on the frog question.
Oh, yeah: railroads are found in a military chess variant, and monkeys are
found out in the open, under the sky. If you don't believe me, ask
Christine [just in case you weren't sure ;-)].
