When there is a fraction too much friction it is time for some light relief!

Strange name "ISX" for a horse,
Her breeding a mystery and lacking some history.
But she's fit and prepared for the course,
With JK in the saddle she is ready for battle,
No time to consider remorse,
Big event the "World Stakes" does she have what it takes,
To make a big hit on the bourse,
But no matter what anyone thinks,
This mare could be better than Winx.
