As the old saying goes, "Chess is 99% tactics". That is completely wrong. Tactics are for in-moment-positions, but what comes next in importance is positional chess.

However, if one is in a horrible position, as long as the opponent plays accurately, not many tactics could be exploited. The following game demonstrates this.
Note: I am not a professional chess player. My annotations are from my own perspective, not those of a professional chess player.
Update: I realized there was a mistake in my annotations, so I corrected it. (Parenthesis analysis of move 15)
