Avalanche chess

Avalanche chess is played on an 8x8 board, each player initially has
- 1 King
- 2 Knights
- 20 stones in hand
Initial position:

A player's move always consists of:
- placing a stone from the hand onto the board (till there are no stones left in the hand)
- moving with a knight or the King (there is no capture)
Each move with the King or the Knight is immediately followed by displacing chains of adjacent pieces:
- Each piece adjacent to the square where the moving King or Knight ends, is displaced one step away from that square (orthogonally or diagonally).
- If a piece is displaced this way, and the square where it should go to is occupied, then that other occupying piece is also displaced one step in the same direction. This way, an entire
row of pieces could get displaced like an avalanche. Pieces in the Avalanche on the edge of the board will then be removed from the board and count as captured.
The game is won for the player who's enemy King or last enemy stone is captured.

Example:

Black to move could place a stone from the hand on d2, then play Kd7 and an Avalanche (d6-d1) will push the white king from the board. Black wins.

I like the game idea.  Has some relationship to Dynamo, one of the best of all variants, but is original enough to be interesting.  The name, however, should probably be changed.  For decades there has existed a variant called Avalanche Chess that has been very popular in some circles.

I missed that but now I definitely need to think of another name. Thanks for mentioning this.
