In the year of my jubilee, it was a very nice present from the part of my friend Marjan Kovacević to organise this anniversary tournament, with the strong support of Borislav Gadjanski, president of the Serbian Chess Problem Society. From the first edition of 2004, I have met them almost year by year at the International Solving Championship of Serbia (with special minilectures sessions, in which my interventions were in the field of Romanian chess history), so I am grateful to both not only for keeping this composing tourney, but for their whole attitude towards me in these so many years!
The theme of the JT, proposed by GM Marjan Kovacević (with a precious suggestion from the part of Julia Vysotska), was linked to the letter „L” (=50, in roman figures):
„Helpmate in 2 using Lortap condition and Locust (one or more of them) as the only fairy piece”.
There were 40 entries, of 26 authors/pairs of authors, from 15 countries. Being very satisfied of the problems’ level, but also keeping into regard that it is a special occasion, I have decided to give awards to half of them! The awarded compositions are:

Finally, a big “Thank you” to all the composers who have honorated me by participating at this jubilee tournament. All of them are well-known names into our fief, so I regret that I couldn’t give accolades more than the ratio of 50%. But I promise that, at my 60 JT, there will be more awards… you guess how many!

Thematic condition

„L-problem“ symbolized by Lortap and Locust

Helpmate in 2 using Lortap condition, and Locust(s) fairy piece. Other fairy elements are not allowed.

Lortap: A piece can’t capture or give check if it is observed by a piece of its own side.

Locust (L): Moves along Queen lines only by capturing an enemy unit, arriving on the square immediately beyond that unit, which must be vacant. If, in the same situation, instead of enemy unit there is a unit of the same colour, Locust observes it.

In combination with Lortap condition, it would prevent this other unit from capturing or giving check.

Example 1:
white Pc2 Kh7 Bb3d4 Lf4 black Kc4 Rb4

h#2 Lortap; Locust f4

1.Kc4-c3 Bb3-f7 2.Rb4-b3 Bd4-f6 # 1.Kc4-c5 Bb3-d5 2.Rb4-b5 Bd4-g1 #

No check in initial position as Bb3 observed by Pc2! I. 1.Kc4-c3 (no check, Bd4 observed by Lf4) 1...Bb3-f7 ! ( or 2..Bf6 - no mate as observed by Lf4) 2.Rb4-b3 (to observe bK, otherwise 3.K*c2!) 2...Bd4-f6 # (Be5,Bg7,Bh8? - observed by L or wK) II. 1.Kc4-c5 (no check, Bd4 observed by Lf4) 1...Bb3-d5 2.Rb4-b5 (to observe bK, otherwise 3.K*d5!) 2...Bd4-g1 # (Be3,Bf2? - observed by L)

Example 2:
white Pd5 Bf1 Lg5 black Pb6b5 Kc5 Bg7 Rf4

h#2 Lortap; Locust g5

1.Bg7-d4 Bf1*b5 2.Rf4-f6 Lg5*f6-e7 #

(3.K*d5?? - can't capture being observed by Pb6!)
(1.Rd4 ? 2.Bf6 L*f6-e7 3.Rb4 !) (1...Bd3 ? 3.b4 !)
