Patience and Non-Forcing Moves by GM Nadezhda Kosintseva
A chess player cannot calculate all the moves in every position, so at some point he has to make a choice what moves should be computed and what continuations can be excluded from a list of candidate moves as non-promising. In such a situation, many players used to take into consideration only the most aggressive moves that force the opponent to respond in a certain way. Indeed, a lot of chess combinations represent a series of forcing moves that end up in a winning position. But in fact, chess is much more that just calculating checks, captures and other moves with a threat. What's more, if a player looks only at forcing moves he can evaluate the position in a wrong way and as a result miss interesting resources for himself as well as for his opponent. In this lecture, I will show you four instructive examples of how the ability to take into consideration quiet, non-forcing moves in the process of calculation can change the outcome of the game and make one's attack more powerful.
