These weaknesses can be reavealed also in comp-comp games.
The program with knowledge about king safety can win against the program that
plays without knowedge about king safety.
The games are also blitz30 and at tournament time control programs can play
better.
This weakness is about tactics and tournament time control on fast hardware is
going to help programs to avoid more tactical mistakes.
