Thank you very much for the update. It works well on my iPhone 6.
Still, a few things...
No arrow indicators, to help easily move the pieces, have been removed; I missed the smooth transitioning of the pieces when they attack. I like the way before how the panel (the board) used to flip over, that feature was removed as well. Lastly, the automatic sequence of the opening moves have been removed as well with just a a push of the arrow indicator. Hopefully, you can reimplement and add these back on again. Its already too late for me, since I already updated this app.
Chess pro, fan.
