Atomic Openings Explorer

Statistics can say a lot. Especially when there's no clear theory. This application (which is based on more than 700 000 games of top players) is an attempt to better understand the one of chess variants - Atomic. The collected statistics (the first 15 moves) can help players choose the good strategy which will succeed.

What is Atomic chess?

From lichess.org:
- In addition to standard rules, all captures cause an explosion by which the captured piece, the piece used to capture, and all surrounding pieces except pawns that are within a one square radius are removed from the board.
- It is illegal to capture a piece that would blow up your king, nor can a king capture any piece as according to atomic rules, the captured piece blows up and is removed from the board.
- Traditional checkmate applies to atomic as well, but any move that results in blowing up the opposite king will result in an immediate victory, overriding all checks and checkmates.

In Atomic the kings can be connected by moving one into the adjacent squares of the other side’s king. When the kings are connected, checks do not apply. As it is illegal for a capture to blow up your own king, it is not possible to capture the other king directly. To win such an endgame, it is necessary to cause the kings to detach by zugzwang or explode a piece of the opposite color while the king is next to it.
