- deep and sound
Many games, even at Grandmaster level, are decided by shallow tactics - a fairly simple move the opponent overlooked. But occasionally we see something more profound - a "deep" move that requires great foresight or intuition to play. And it is even more impressive if after close post-game examination it is sound in all variations. These games have "deep and sound" sacrifices or other key moves.

Some human chess games are still "too hard for computers:" they showcase talents humans have and computers are imperfect at.
