chess calculation technique


https://www.chess.com/forum/view/game-analysis/calculation-training
Some of the positions in this forum are tough, but it is cool to hear ideas from stronger players and compare their thought process with your own. I recommend attempting the puzzles (without an engine or outside help) and then when done (give up or think you have the solution), then post your analysis in the forum. After this is done, you can read other comments or check with the "official" solutions to see where you might expand your calculation-ability in the future.
