i have mentioned the fact there also - so that people should combine it into one of the threads

Here is an actual game where white demolished black for attempting to copy his moves.
This is probably more likely to occur in a chess game, I would have thought.

I think is the only one solution to 4 moves.
It's a variation with 3. Qh3.
@ knightstour: An interesting game! Yes, it's instructive for a beginer, not only a logical problem!

I have seen this before. It is interesting, but even at a low tournament level this game would never occur

I would say its as likely to occur as any other possible game, which is about 1 in 10^50 or something, but if it happened once it may happen again, since a few beginners would assume you can't go wrong as black if you just copy white's moves and so they won't analyse what they play as much. Just like NN here.

So, what realy happen if black, from the begining, simpllly reproduce white moves? He/she will be mated in 4 moves! I expected to see this solution under the name advantage of moving first - mate in 4 in symmetrical position here. So, a give it as a puzle.
