Explanation of the columns

"Rank" — 1 is best, 2 is second best, etc.. Note that only best engine version wich played at least 150 games may have rank, that's why many engines don't have any rank.
"Name" — Name and version of an engine, including settings, 32/64-bit and number of CPUs. It has green color if an engine is free.
"ELO" — Engine rating computed with Bayeselo.
"+" and "−" — 95% confidence intervals. For example, if engine's rating is 2850, "+" is +20 and "−" is −15, it means that there is only 5% estimated probability that engine's "true" rating is outside of the [2850−15 .. 2850+20] range.
"Score" — Number of points scored by an engine, divided by the number of games. Win is 1 point, draw is 1/2 of a point, and loss is 0.
"Average Opponent" — Difference between the rating of engine tested and average of the opponent ratings for all games played by that engine. Positive number means that engine was playing with stronger opponents, averagely. Negative number - weaker opponents.
"Draws" — Percentage of games by an engine, that ended in a draw.
"Games" — Total number of games played by an engine.
