Fighting as Aleksandra: Use Low Kicks for focus and once you have at least one focus, you can use her Shin Kick in place of the Round Kick and get a higher to-hit.  The Knockout Kick is tough to save up enough for, but it can turn a fight quickly.

Fighting against Aleksandra: It’s awfully tough to trade blows with her in the standing game, no matter how good your standing game is.  If you’ve got a ground game, go for it, if you don’t, good luck.
