The achievement system is buggy. If you contact Support, they might be able to do it manually for you. However, the staff are reworking the achievement system.
How to get the introspection
@sonofwisdom17: for the "Introspection" achievement, you must first go to the explorer (https://www.chess.com/analysis/explorer). By default, the explorer selects "Master Games"; the users with a paid subscription can click on "Master Games" and choose "My Games" instead; then they must explore their games beyond a fifth move.
please anyone respond
