The Polish Opening begins with 1.b4 and develops the c1-bishop to b2 before White occupies the center. Its point is not a quick trick: the b-pawn gains queenside space, the bishop pressures the long diagonal, and c4 or e3 challenges Black's center. This trainer turns those ideas into exact move orders, tactical checks, and board-verifiable plans.
Study eight direct lines: two Main Line treatments after ...Bxb4, two Schiffler-Sokolsky structures, the closed and advanced German Defense, the Bugayev center, and the forcing b4-knight trap. Each line connects 1.b4 to a concrete pawn break.
