I partially agree with M Winther. I have two points to say in this regard:
1. White forcing black to react from move 1 can give White a HUGE
advantage in the game. An example of this, since White's advantage in
Atomic Chess (which is played quite regularly in FICS,) is very well
established that you are not required to give a rematch if you win with
black!!
2. However, this factor didn't prevent Atomic Chess from being one of the
most fun playable chess variants.
