BPCF 2017 - XII Београдски фестивал проблемског шаха 2017.
Belgrade Internet Tournaments 2017
Group C – HS#Max2½,
2 Solutions
Judges: Participants of the BPCF,
solvers of this problems
This tourney was a very exciting one, for both participants and the organizers. The initial idea
was to avoid computer testing, in order to make composers train their solving, while giving solvers
the forgotten pleasure of looking for cooks... This concept soon had to be abandoned, because
Christian Poisson
was very quick to create the program for HS#Max, the new fairy genre that includes only one new
element when compared with HS#: the last two half-moves ask for S#1 Maximummer, instead of usual S#1.
On the other hand, we have to be grateful to Christian for saving composers and organizers from
additional work, and for ensuring HS# Max an official status in the endless sea of fairy genres!
Besides, it helped to receive only 1 incorrect entry...
The method of judging was the same as in our previous Composing/Solving/Judging events. After
solving 18 correct entries, the eight solvers selected some favourits and analyzed them on the
demonstration board. Next day they gave marks to all 18 entries, from 1 to 10.
The average marks of the first 4 compositions stood out, and were differentiated with slightest of
margins, from 8.43 (the 4th place) to the 8.75 (the 1st place). Since there was no single judge, some
comments given by solvers were summed up in the following award.
Thematic condition
Helpselfmate Max in 2½ moves
Helpselfmate Max is a new condition, with the help-play before the last two half-moves, presenting S#1 Maximummer (Black has to play the geometrically longest move).

1... Rg8-c8 2.Qh8*c8 Rf5-b5 3.Qc8-a6 Qg5-c5#
A complex combination of sacrifice and pinning (of attacking pieces), two characteristic
thematic elements that prevent longer moves by black. The whole content is harmonized in
ODT form, with Bristol clearance, black half-pin, and anticipatory self-pin.

Each half-move is highly thematic here: preparing the longest
move of mating piece, closing long black line, anticipatory self-pin,
pin, and return of mating piece over the same line. Complete
analogy of solutions.

Astonishing OD play in Meredith, with 3rd black moves being the thematic
pinnacles. BQ has 3 moves to annihilate one WR and find the right positions
on different edges of the board.

Another deep and strongly unified ODT concept, based on the characteristics of the genre.
Capturing of white unit, serving as both critical and anti-critical move (!), determines
the remaining self-block on c3 and the choice of play.
