Every Monday you receive an email with a Test consisting of 6 positions. Spend 45 minutes total, like in a game, note your decisions for every position. Then watch the Solution video where I walk through every position: the right thought process, why tempting moves fail, and what to focus on to improve.

RCT is built for players rated 1500–2000 Chess.com Rapid/FIDE (or ~1700–2200 Lichess) who want training that matches what happens in a real game. You get no hints. It will be hard. You'll be under time pressure. Some weeks you might score 0/6. That's the point. If you want comfortable training, this is the wrong place.
