Champi is one of Ed´s newer creations based on a pass-pass-self. Compared to MinuEd, it´s really easy so try this one first if you want to mess around in pass-pass-self...

A   iB(p)|pcs| becomes B

B    pps|pps| becomes M

M   pcA|sAB| becomes A

The start is left-handed pass!

As the pattern has (only) 2 beats, it is asymmetric (meaning that each chop is thrown from the right hand of A)!
