oh pleeze, my phone came with a chess app, (ok I got it used) I am pretty sure it was there preloaded, so I mean that app and no I can't distinguish between the pieces for instance a bishop and a pawn look almost exactly the same. I am not the first person who has pointed out the weakness of chess here and I just was making the point that many things are half baked. no take back move? close app by minimizing and then repeatedly trying to hit the little x? common...and you found my post offensive? wow you must be touchy.
