BPCF 2017 - XII Београдски фестивал проблемског шаха 2017.
Belgrade Internet Tournaments 2017
Group B – h#2 ,
Helpmate in two moves
Judge: Miodrag Mladenović
I received 44 problems without author names from neutral judge Borislav Gadjanski. The quality of problems
was very good since there was very short amount of time available for composing. After reviewing problems
I found out there are three non-thematic problems: #10 (RK), #14 (YB) and #32 (D-C G). Also, there is one
problem with three WRs. Although it was not specifically stated in the announcement of the tournament that
it was forbidden I found out there is no justification for using the third rook. So I did not rank this problem
at all. I decided to rank 17 problems:
Thematic condition
White-Black + Black-White form of the Klasinc theme
a piece A opens a line to allow move by a line-piece B of opposite colour (gate-opening), then the piece A performs switchback. At least two thematic phases (multiple solutions, or set-play + solutions accepted, but not twins!).
Example -(Scheme)

Both forms in 2 solutions, the only example we found!

Required theme shown in combination with Zilahi theme. At first I was thinking to place this problem at higher place but when I found out that three black powns could be saved by slightly modifying position (3kr3.pKsps3.3Rb3.8.3q4.b2p4.1B6.8) I decided to lower down ranking of this problem.

There were several problems using same scheme but only three of them were showing minor black promotions in very economical position. Since positions are almost identical I decided they should share 1st-3rd Honorable Mention.
