Default Collection of my Diary Problems

Hello all,

I placed a *dipr.pgn* file (pun intended) in a directory on my homepage.

It contains the problems I have posted here, in total 38. It does not
contain the answers as most problems do not need more then 1-2 minutes to
solve, though some of the problems need some more (or non-engine)
experience.

Best regards,
Fernando


*Note that it won't be updated often.

The problem is that fernando mixed the order of some tags in the headers
of the games.

Try with this (copy and paste as a pgn file):
