Atomic Chess

He has seen this game in the Dutch orthodox chess Server, (DICS: telnet 5000 ( 5000) ).

The atomic chess rules are deduced by a collection of statements from friends of this game. The general ruleset follows:

  1. The normal chess rules are valid.
  2. Whenever a piece is captured, the capturing piece is removed and all pieces on the immediate horizontal, vertical and diagonal neighbour fields.
  3. Pawns are exceptions to rule 2. They do not explode, but cause explosions when taking away other pawns and pieces.
  4. Explosions are non-recursive, meaning that only the pieces on the immediate neighbour fields are removed, not pieces in further distance (no avalanche effect).

These rules imply that the King may never capture a hostile piece, avoiding his own explosion.

Hint: Watch the Knights!

What happens if you skip rule 3. So pawns explode too when they capture something. Is there a forced win or not ? It is not so easy.
