In chess, tactics are usually shorter term moves that aim to gain material advantage or mate. Pins, skewers, discovered check, forks, double attacks, etc. These are usually in a time frame of around 2-3 moves. This is often described in chess terms as 'concrete' threats. Strategy concerns more of theoretical ideas, long term possibilities. 10+ moves ahead. This involves pawn structure, where your king is positioned, how your pieces are developed, which side of the board left or right you might launch an attack, end game considerations, etc. How you intend to defend or win the game. This type of play is usually called positional. Whereby the placement of your pieces gives you an overall advantage. In GM level play this is very subtle and 15+ moves ahead. Positional vs. tactical. As an analogy tactics are like cobra strikes and positional play is like a boa constrictor where tiny shifts strangle the opponent in the end. Both are lethal.
