Avalanche Chess

This variant was invented in 1977 by Ralph Betza. It was frequently played in both NOST as in AISE, two past postal correspondence groups for Chess variants. In NOST, the game was one of the 20 most popular CV's, probably in its top 5. The game is mentioned in David Pritchard's Encyclopedia of Chess Variants and given its own chapter in his Popular Chess Variants. It is also described in R. Wayne Schmittberger's New Rules for Classic Games.

This game can be played via email on Richard's Play-By-eMail Server.

Below the description of standard avalanche chess, a description is given of a variant, designed by Alessandro Castelli, with the object of decreasing white's opening advantage.

Rules

The rules of normal chess are followed with these changes:

Comment

White has a large advantage. White's advantage is reduced in BALANCED AVALANCHE CHESS in which White had no pawn push on the first move.

Here are two sample games on Balanced Avalanche Chess, sent to me by Alessandro Castelli.

Avalanche Reversed King/Queen Chess

Alessandro Castelli (email removed contact us for address) ink.it proposed a variant of Avalanche chess, named Avalanche Reversed King/Queen Chess, Avalanche II Chess, or Castelli's Avalanche Chess. Castelli is the International Champion and the Olympic Champion on standard Avalanche Chess.

In this variant, Black starts with the King on d8 and the Queen on e8. This artifice stops the threat: Qh5/f6+ and equilibrates the play.

Here is a sample game.
