Polish Opening Baltic Defense Discovered Attack in Chess

In the Polish Opening Baltic Defense Discovered Attack, White uses the Polish Opening setup to enable a discovered attack—most often by moving a piece that was blocking a line (commonly along a diagonal or file) so another piece suddenly attacks a target. A defining feature is the tactical “reveal” after a preparatory move, where the Baltic Defense’s structure helps create a clear line for White’s follow-up. For an intermediate player, it’s about recognizing when your move both improves position and uncovers a direct threat.
