The Walking Knight

Post by Glarean »

It is very worthwhile to take a closer look at the games of the TCEC tournaments! You can find real pearls there.

For example in the game rofChade 2.3 vs Stoofvlees II a14 a few days ago.
There an impressive walk of a knight happened over the whole board.

Such "strategic" moves are usually only seen in human chess:

Yes, computer games between strong engines work like this: they gradually accumulate "insignificant advantages",
which then lead to victory in the end.
