"really bad chess" smartphone app

I'm good at chess, but was never a chess-nut studying openings and the lot. I migrated to "Go" for many years for the varied intellectual challenge that the static chess board layout did not. Then my teenage son introduced me to "really bad chess" for the smart-phone...

Talk about bringing excitement and variability back to chess!

"really bad chess" continually pits a changing line-up of chess pieces for you against an opponent, whose pieces most likely will not be a mirror of yours. Think replacing pawns in the starting lineup with additional bishops, knights, rooks, and even queens. As you move up and down in the ranks, the number of powerful pieces your side possesses varies with respect to your opponent's.

The study of chess changes when, say, you have two or more bishops on the same color; or a bishop / knight heavy line-up's, even on the front-line where the pawns used to be.

Just putting that out there. It has become the number one application in my phone to drain the batteries and necessitating re-charge well before a wakeful day is over.
