Line-Opening Sacrifice
What it is
A line-opening sacrifice gives up material to blast open a file, rank or diagonal — usually a pawn sacrifice against the king's shelter — so your heavy pieces and bishops gain open lines to attack.
When to use it
Use it in attacking positions where your pieces aim at the enemy king but a pawn or two blocks the lines. Opening those lines is worth material if the attack crashes through.
How to use it
Find the closed line pointing at the king, sacrifice to remove the obstructing pawn or piece, and follow up immediately with checks and threats down the newly opened line before the defender regroups.
