A List of Chess Tools

I wish to compile a list of all available chess tools that you guys know of, I'll start with the ones that I've heard about and use myself and I hope you guys chime if you know about a chess tool that isn't listed here. Thanks (: So the ones I know of and use are Chess dot com Lichess Chessable Chessmonitor I'm looking for puzzles and other kinds of training for beginner/intermediate player with focus on "learnable" fundamentals/constants that new (serious about learning everything from scratch) would greatly benefit from. Is there some tool out there with systematic approach in teaching one ALL of the fundamental rules, positions, and variations? Something that also teaches us how to teach ourselves, accelerated learning something... Peace
