Chess calculation is seen by many players as vitally important and indeed especially for beginner to intermediate level players, it is is often calculation skills which enable most games to be won or lost. However, the more advanced we get as chess players especially Super-Grandmasters like Magnus Carlsen, the more we can evaluate positions based on our prior experiences of other games and use our pattern recognition skills to often simplify calculation and short-cut which is useful for conserving mental energy. This video takes this premise to the maximum for the sake of a nice debate - about how much we actually need to calculate and raises the possibility that in fact the strongest players may try and calculate as little as possible to be as conservative as possible on mental energy and put priority into just forcing move variations where needed at critical junctures of the game.
