Tactics Training Suggestion

My name is Lauren Goodkind and I'm a chess teacher based in the San Francisco bay area.
I think you need to find what works for you. I think most people, including me studied specific categories of tactics regardless what stage the game is. This includes: fork, double attack, skewer, pin, and more.
One tip to develop tactics: pay attention to what pieces are on the same line as your king and queen. Also what pieces are on the same line as your opponent's king and queen. Always consider all checks and captures.
I created many puzzles that help you with tactics. I invite you to solve puzzles on my website: https://www.chessbylauren.com/two-choice-puzzles.php.
I hope that this helps.
