Polish Defense
Black answers 1. d4 with an immediate queenside land grab. It brings a fianchetto, control of c4, and an opponent who is out of book by move two.
1...b5 does three honest things: it takes queenside space, it prepares ...Bb7 on the long diagonal, and it covers c4 so White never gets the ideal c4-plus-d4 pawn pair. The price is just as honest. White is welcome to build the full classical center with e4, and the b5 pawn itself will need tending once a4 arrives. Nothing about the deal is hidden. It is a bet that flank activity and diagonal pressure can outweigh a textbook center.
Games tend to follow a script with sharp details. White takes the center, and after 2. e4 Bb7 the e4 pawn already needs defending. This forces even the most ambitious center-builders to spend moves on upkeep. Black chips away with ...a6, ...e6, ...Nf6, and a well-timed ...c5, sometimes tossing in ...b4 to fix the queenside and take c3 away from White's knight. The middlegames are lopsided on purpose: White owns the middle, Black owns the diagonal and the queenside, and the better plan wins.
The name places it beside the Polish Opening, 1. b4, the same idea with colors reversed. Serious theory has never taken the defense very seriously, and that may be missing the point: at club level it is a weapon of surprise and structure, not tricks. If you enjoy positions where both players are thinking from move two, this is one of the cheapest tickets there is.
Take what is offered, calmly. Build the center with e4, or choose the solid e3 and Bf4 setups, develop toward the kingside, and treat b5 as a long-term mark. A4 at the right moment forces Black to spend resources holding the queenside together. Do not launch a refutation hunt; there is no forced punishment, and overreaching in the center is exactly what Black is fishing for. A normal middlegame with more space is the win condition of the opening phase.
Everything routes through the b7 bishop. Get it onto the long diagonal quickly, support the advanced pawn with ...a6, and chip at the center with ...e6, ...Nf6, and ...c5 rather than trying to occupy it yourself. The advance ...b4 is your positional trump. It fixes your space and denies c3 to White's knight, but spend it when it gains something concrete. You are not playing for textbook equality; you are playing for a middlegame where your targets are clearer than White's.
At club level (1600-2000 on Lichess) the Polish position appears just over a million times. Set against more than 622 million community games beginning 1. d4, which is exactly why most opponents greet it with a long think. White's favorite answer is the principled 2. e4, played at 40.3% and scoring 52%; 2. Nf3 (17%) scores 53% and 2. Bf4 (14.1%) scores 51%. None of the five most common replies pushes White's score out of the ordinary 51-53% band, so the defense is offbeat but not unsound: you give up a little to take most opponents somewhere they have never studied.
