Variant of the week: Avalanche chess

Avalanche chess is a chess variant designed by Ralph Betza in 1977.

Rules are as normal chess except for the following:

1. After you move one of your own pieces, you must move one of your opponent's pawns one space forward toward you.
2. You cannot use your opponent's pawn to capture and you cannot move your opponent's pawn two spaces forward.
3. If none of opponent's pawns can be moved, then that part of the turn is skipped.
4. If you must move your opponent's pawn to promotion, then your opponent chooses to what piece it promotes.
5. If moving an opponent's pawn gives check to you, then your opponent wins the game immediately.

Eg:

Interesting! Care to play?

Alright.

You start.

1. e4/f6 c5/c3
2. d4/c4 e5/f3
3. Bxc4/h6 Ne7/g3
4. Qb3/g6 Nc6/d5
5. dxc6/g5

2. f5\f3

That's c5/c3

(In detective-y voice) By jove! You're right! And to think we'd been on the wrong track all this time.

d4/c4, unless you can take ep

No... I don't think I can take ep. e5\f3

Bxc4/h6

Knight e7/g3

You know I never learned the abbreviations of the peice names. Could you quickly fill me in?

The letter that it starts with, except for knight which is N.

Qb3/b6

But bishop id bx? Nc7/d5

The x means captures. And make sure that it's a capital B. A lowercase b means the the b pawn.

And Nc7 is illegal.

Sorry, Nc6

dxc6/g5

What a creative way to hang a piece!

Wow. That was really stupid. I need a board to look at. Can I make that move again?

No problem; Go ahead. And you can use the analysis board.
