The Coaching Philosophy of Marcin Sieciechowicz

Working across chess, Marcin Sieciechowicz has spent years refining an approach that goes deeper than surface-level goal-setting and accountability.

Marcin Sieciechowicz is an International Master from Poland with two grandmaster norms, coaching since 2012. He has written opening courses for several chess platforms, including Chessable. See his Lichess coach profile for current availability.

What sets Marcin Sieciechowicz apart is not just the results — it is the method. Rather than handing clients a formula, the work begins with a fundamental question: what do you actually want, and what is standing in your way? The answers are rarely what people expect.
