⚔ The Four New Pieces

Meet the Newcomers

Beyond the classic chess pieces, PK Chess introduces four powerful new pieces drawn from Thai mythology and chess theory. Each one transforms how the game flows.

```
X
Athkhon
อาคโคน
A sneaky tactical piece. Moves like a Bishop diagonally, plus 1 square forward/back, plus a unique 2-square sideways leap that jumps over adjacent pieces.
21 max moves
Y
Akkhan
อาคข่าน
Symmetric warrior. Combines extended knight jumps with adjacent attacks in 14 directions. Master of close combat and surprise raids.
14 max moves
A
Archbishop
บิชอป-อัศวิน
The legendary chess hybrid. Moves as both a Bishop and a Knight combined. Devastating in open positions and lethal at attacking the king.
Bishop + Knight
C
Chancellor
เรือ-อัศวิน
The endgame powerhouse. Moves as both a Rook and a Knight combined. Worth nearly as much as a Queen — a true game-changer.
Rook + Knight

⚜ The Story

A Vision Born in Bangkok

PK Chess started as a single question: What if chess could grow without losing what makes it timeless?

"I wanted to create something that honors the depth of international chess while weaving in the rich mythology of my homeland. PK Chess is that bridge — where ancient strategy meets new horizons."

Two years of refinement, hundreds of test games, and countless iterations later — PK Chess is ready for the world. Free to play, designed to inspire.
