What a wonderful site! I had been looking for something like this, and this site is no doubt the best one I found. It has helped me improve my tactics, board vision, and subsequently my game. So I just wanted to thank you. If I could think of some improvement, it would be to automate the right answer as an option, but it's no big deal, just a minor improvement . The site is really great as it is. If I can think of anything else, I'll let you know!
