Glad to hear :-)

If something is fishy, it's in the is_king_tableau. Make sure that
function does what you want.
sage: def is_king_tableau(t,no_of_rows):
....: for i in range(no_of_rows):
....: if t[0][0] != 1:
....: return False
....: elif t[i][0] <= 2*i:
....: return False
....: else:
....: i=i+1
....: return True
The i=i+1 is suspicious. If you really want to consider rows of even
index, it's more explicit to use range(0, no_of_rows, 2).
Also the t[0][0] might as well be outside of the loop since it does
not depend on i.
Cheers,
