Personally, I really do mean it when I say that I am a big fan of chess.com. I have been a paid member since 2016, and before that I had a free account for some time. In neither instance have I ever been aware of excessive cheating or other "tricks". The website has invested a LOT in trying to prevent this sort of thing, and have very good automated algorithms monitoring for unfair play on a ongoing basis. Regarding game analysis tools, these too are top notch and will give you a good feel of where your strong and weak points are with regard to tactics, phases of the game, etc. Customer service has been consistently friendly and responsive, only keep in mind you may need to give them a day or two to get back. Functionally, the board used here is far better than with any other chess websites I've tried, very smooth easy to navigate. I never thought I'd like a website so much that I'd log over 140,000 3-minute blitz games in 9 years, but I think in and of itself this says a lot regarding how I feel about chess.com. Recommended! :)
