2020-02-21 17:50:44 +0000 UTCStockfish was a good choice. Few factors that determine the strengh of a chess program: 1) The evaluation function and values that let the engine determine the numerical value of a position. The knowledge how to do that has greatly increased, a lot of "chess knowledge" goes into those functions. E. g. a protected pawn is more worth than an unprotected pawn, king safety is valuable, 2 bishops are slightly more worth than 2 knights. 2) Hash table size - if the computer reaches the same position on different paths, it can stop calculating that branch again. 3) Hardware of course 4) All the tricks found in other engines :-) Like null move pruning. Simplified - any modern engine that utilizes the chess engine knowledge of recent years, will likely beat any older engine (running on the same machine and similar settings). And what a shock it was when AlphaZero, the KI from Google came along - and learnt all its chess knowledge (only the basic rules were hard coded) by playing against itself in a such a short time - and it easily beat the best chess engine equipped with "human chess knowledge". Great video! I like the "let's see what happens" series so far
