Chess Training for Grumpy Geezers
Must say I like the image very much. Helas I do not know anything about a good chess app for an iPhone.
tChess Pro (my absolute favorite) supports annotations now, but only comments (no variation lines as of yet!)
And also... although I've got a lot of "issues" with the UI design, I do enjoy the HIARCS app also - just based on its "personality" (play style).
That is one huge step forward. Still, I will probably wait for variations.
