Chess Premium 4+

I really love the look and feel of your digital rendition of Chess. I paid for the “premium” version of your game so that I could enjoy its simplistic beauty, undistracted by ads, so I thank you that I am able to do so. This app is beautiful, timeless, and something I can see myself playing until the iPhone 25.
To further improve the experience for each and every one of your customers, I have come up with a few suggestions that, if implemented, will make the experience of using this app even better than it currently is. I thank you in advance for considering the following:
• “Undo” after checkmate
This will allow us to further evaluate our strategies, because we’re all prone to making mistakes and, as a beginner, I may not always see that a checkmate against me is about to take place.
• The ability “Save” a game to rewatch later
Each chess game is a unique piece of art, so it would be great to be able to revisit one of our masterpieces!

Again, I want to thank you for taking the time to read what I have shared.

Best regards, Sam

If I could recommend anything, it would be maybe an extra color or two. Right now there's only bronze and silver looking pieces, but I think black and white pieces would be nice and simple as well. Also, whoever is bronze ends up being the person who goes first. Nothing is too big a deal, but some people I play with have preferences for the colors. The game plays well, and I use it a lot with others. The algorithim definitely keeps me on my toes.

Having been a former USCF rated expert (2005 rating), I find this app to be all the challenge I need in my bucket list attempt to reach a master level. I play it on full strength with some limit to time since I can explore more plans/strategic lines this way. As expected, the tactical capabilities of this on a iPhone 6 are well beyond human, so much so that the app seems to almost play positionally. With this type of strong opposition, one can explore variations much more quickly and improve more quickly as well.

However, since it can’t read PGN files, it is therefore limited in its full capability for training purposes. This is a shame, since otherwise it is a very powerful player.
