When analysed 2 games of 2 friends from my chessclub, I've found 2 interresting
positions. For the 1st the eval constantly droped (a trapped knight, again), for
the 2nd there are many fail down because king is attacked in the middle of the
board !
I hope someone will be interresing in this 2 positions (french notation):

The revelant games are :
1) In this game the white didn't play 6. Ng5 because it's too complicated;
6...O-O seems to be a blunder in the computer view (you may start the engine
after 6...O-O and see eval very high and drop drop drop) but in the human view
the idea is to trap the knight
