I will eliminate this position because I already had some doubts about it.
It is suppose to be a saving move (to keep black in the game) but I was not sure
that it did a good job. All the rest are _much_ worse but as you say
is not that interesting. It is quite easy already, so combining all things
together it is not worth the trouble.
I will check the other two.

Miguel
