Despite the name, Paulo Vitor Damo da Rosa outlines 2 rules that help guide his decision making in game, explaining why it is often correct to make a worse play than one which appears available, if it takes away choice from your opponent. He also explains what to do when your opponent acts in a way that doesn’t force you into a line. At high level play this thinking is extremely useful, however it relies on both players agreeing on the value of pieces and plays, and can therefore be misleading when playing in a situation where you have a skill advantage over an opponent.
Reasonably useful short guide for an important concept which feels under explored in this article. First section is premise, last section is an example. The middle section entitled ‘Step by Step’ is of the greatest value, if you are short on time.
