I know about what the old masters have written about the importance of endgame
technique. I used to believe it myself. I'm an NM who likes the endgame very
much and have studied it quite a bit.

However, in my personal experience I have encountered many SMs, IMs and even GMs
who lack knowledge about the endgame that I myself had taken for granted. Given
that they are higher rated than me, I was forced to the conclusion that endgame
technique is not so important as I had been led to believe.

More important is the ability to calculate complex middlegame variations
accurately and knowledge of opening theory. I calculate rather well for my
level, but opening theory is my weakest part of my chess by far. It is the area
of chess I very much despise. I would be quite happy if the chess world shifted
to FRC.

If you think about it, you would realize that chess programs are as successful
as they are for very similar reasons as the pros are. Computers are very strong
in the opening phase with their perfect and voluminous memory plus they
calculate very well in complex middlegame positions. Despite being relatively
weak in the endgame compared to GMs (except for 5, 4 & 3 man endings, which are
rather rare, they are able to give even super GMs a bad time, because the first
two stages of a game of chess, the opening and middlegame are simply much more
important than the endgame.

BTW, one of the results some have posted here at CCC is that programs playing
with EGTBs do not perform significantly better overall than playing without
them. EGTBs are just not that big a deal for overall playing strength.
Surprising, but true. They are great for analyzing such endings, but they do not
help often enough in games to be of much consequence.
