New Puzzle Theme Balestra Mate

[Dirkster99]

I have collected mating patterns on the Balestra mate using a Python script as described here. I have considered all final mating positions where the Queen and Bishop team up to mate the king as shown in the practice section, but of course including positions where the King is on the h file, or on the first rank etc.

The parser identified 1041 positions that adhere to the above definition, but 14 of those positions where invalid, because the bishop was not actually mating the king since it was blocked by another piece.

This error brought the total number of positions down to the 1027 positions in the file attached to this ticket.

I would suggest either of these icons:

Here is the CSV file containing the references to the reviewed puzzles that should be tagged:

The Google CoLab parser is not perfect, yet, but close to stable.
