Annie will prevail in the 9th in a hard fought decisive battle.

She will pull her knickers down in the 4rth and knock him out :)

She will win just before Round 1. King Ferdinand will chicken out. 

Obviously it will go to the wire, 9th round.

Round 13 

First round 

Round 4 after some sparring.....

Round 3

First round

1st round

She will drink him under the table before it all begins..... but he can take a beating.. so my guess round 7

will win in 3rd round

I guess Captain Ann will knock out the King in the 7th round.

My queen will win in round 2.

The King is a dirty fighter; he bites, head butts and hits below the belt to win his matches.  But Annie is a sea witch with special talent.  The first time the King tries to hit Annie below the belt....with no results, Annie will counter with a timber shivering upper cut which will lay the King out in one minute thirty seconds into the first round.  Dont play dirty with Annie or you will find yourself at the bottom of the sea.

She be flattening his snout, she be.  They'll be calling him King Canvasback after the SIXTH Round, they will.

3rd round.

The king goes down in the fourth round. cap'n Anne wins with KO

my guess is the 3rd round
