What would be the added value of an average and aspiring chess player like me to play against Stockfish 14 instead of one of he previous versions? I feel I'll never challenge the maximum capacity of such an engine.
I do not see chess engines as good sparring partners, but rather as tools for effective chess exploration.
The nice thing about these newer engines is that they are starting to be useful tools to explore more sacrificial and unbalanced positions which are really fun to get over the board against humans.
Finding these ideas with the help of a computer gives a competitive edge against other humans, as well as helping discover interesting corners in this vast game.
When you play stockfish at a human level, it is purposely choosing an answer it knows is worse ^.^
