The bishop pair means you’ve got both of your bishops on the board while your opponent has swapped at least one of theirs off — usually leaving them with a bishop and a knight, or two knights.
Here’s why players get excited about it: a single bishop can only ever touch half the squares (its own color). But two bishops working together cover both colors, so nothing is off-limits. On an open board with pawns cleared out of the way, that combined reach is genuinely powerful — the two bishops rake long diagonals from a safe distance and dominate an enemy knight that can only crawl one hop at a time. Strong players value the pair at roughly half a pawn, which is why “winning the bishop pair” is a real, bankable advantage even when the material is dead level.
One catch: the pair loves open positions. In a locked, blocked structure full of pawn chains, a nimble knight that hops over the blockade can actually be the better piece. So the real skill is opening the game up when you own the two bishops, and keeping it closed when you’re the one stuck with knights.

Mini-FAQ
Is the bishop pair always an advantage? Nope. It’s most valuable in open positions. In a closed, blocked pawn structure, a well-placed knight can outperform a bishop that has nowhere to go.
How much is the bishop pair worth? As a rule of thumb, about half a pawn — small but real. Over a long game it adds up, especially heading into the endgame.
