Good coach! I've had ~35 lessons of various themes. Lessons consist of circa 1 hour of chapters going over key moments in your games, and other games of various levels. Lessons often start off light with tactical puzzles of varying difficulty, often with a theme you've decided on before-hand. When going over games, Richard often checks various lines with the help of an engine. Whether this is positive or negative is of course subjective, but it doesn't diminish the lessons as a whole. Engine lines can be more or less useful, but he doesn't hesitate to answer any questions, including unintuitive engine lines! I'm around 1200 FIDE, and he's very good at coming up with studies suitable for my level, as well as very challenging puzzles that train your thinking. Strongly recommend this coach, and the price is perfect for students as well.
