Five layered systems make every game a tactical puzzle. Mastering chess movement is just the warm-up.
Each piece deals damage and has hit points (Damage/HP). Pawns 2/2, majors 2/4, Queen 4/4. Pieces survive attacks — every move is a combat decision, not a binary capture.
Rooks cleave perpendicular, Bishops splash diagonal corners, Queens sweep a 3-square cone in their movement direction. Position matters — not just targets.
Knights stack offensive auras (×2 damage per stack). Kings shield neighbors (½ incoming damage). Stack Knights for devastating combos.
Hit a pawn but don't kill it? It strikes back. Direct hit or AoE — surviving pawns retaliate before the dust settles.
No checkmate puzzles. No stalemate stalls. The first King to reach 0 HP loses. Combat is decisive — but five draw conditions keep games clean.
Promote to any missing major piece — or grab a second Queen if all slots are filled. Promoted pieces enter at full HP.

This isn't a bolted-on chess engine. Our AI uses iterative-deepening minimax with α-β pruning that natively understands HP, AoE damage, buff auras, and pawn counter-attacks.
