Reference 155 After clicking on the function the evaluation is copied into the notation. Copy lines to notation: This copies all existing variations (not just the selected variations) into the notation. The following is an example of copying lines into the notation: What does “Engine/Game Correlation” mean at the top of the notation after the Let’s Check analysis? This value shows the relation between the moves made in the game and those suggested by the engines. This correlation isn’t a sign of computer cheating, because strong players can reach high values in tactically simple games. There are historic games in which the correlation is above 70%. Only low values say anything, because these are sufficient to disprove the illegal use of computers in a game. Among the top 10 grandmasters it is usual to find they win their games with a correlation value of more than 50%. Even if different chess programs agree in suggesting the same variation for a position, it does not mean that these must be the best moves. The current record for the highest correlation (October 13th 2011) is 98% in the game Feller-Sethuraman, Paris Championship 2010. This precision is apparent in Feller’s other games in this tournament and results in an Elo performance of 2859 that made him the clear winner.
