11-piece Meredith with 4 thematic Black pieces and undoubtedly the best composition in tourney. Wonderful thematic realization included 2 Excelsiors with switchbacks of promoted Pawns to their original squares! Also two promoted pieces and Black Queen create self-blocks on f7, g7 and h8. Bewitched me how one very difficult idea can be realized in so light setting!

Black’s move forms shape of an inverted flying Kite. (authors.)
Longest problem in tourney. Another meredith but with only 3 thematic pieces and wonderful content with double Rundlauf! Black King make 22-move thematic switchback-maneuver to a7 square, with Rundlauf as his part. Here we have several pre-thematic switchbacks of BK(on e5-d6-e7-d8-c8-b8-a8) but they are allowed as part thematic switchback-maneuver. Black Be4 open the lines for BK and also make Rundlauf-maneuver! Capture WPc3 open line for mate on a3 after switchbacks 3 Black pieces.

Very interesting concept with staggered switchbacks and annihilation of white mass. Black Rg5 must close the line e2-h5 to prevent check by Bh5/Bf3. On the squares vacated by thematic Black pieces after capture happened Black self-block on e6 and White mating move on f1! Nice idea.

4th Prize - No 27, Seetharaman Kalyan & Velmurugan Nallusamy (India) bk6/qrn5/1p2p3/bp1P4/1pnP1p2/1P1R1K2/8/8

1.Sxd5 2.Rh7 3.Qg7 4.Qxd4 5.Qg7 6.Qa7 7.Rb7 8.Sc7 Rd8#
Excellent idea with only three thematic switchbacks by Q, R and S: Black open line d3-d8 step by step, created reciprocal Bristol by BR and BQ! Also here are three unblocks and three upside-down self-blocks of squares a7, b7, c7. Very good construction.

5th Prize - No 20, Menachem Witztum (Israel) & Ricardo de Mattos Vieira (Brazil) & Ofer Comay (Israel) 3bb3/N2k1p2/3P4/4P2K/8/8/4P3/3RR3

1.Ke6 2.Bb5 (f5? check!) 3.f5 4.f4 5.f3 (Bxe2? check!) 6.Bxe2 7.Bb5 (f2? check!) 8.f2 9.f1R 10.Rf7 (Be8? check!) 10.Be8 11.Kd7 e6#
In the first hand No 20 was not candidate for prize, but after further analyze I upgrade his order. Here are only 3 thematic switchbacks, but one with Excelsior and high-original determination of Black moves! The moves by the BBe8 and BP are connected and they must wait for each other to avoid check to the WK. Thereby promoted R must return to f7! Also beautiful mating setting with three pairs connected pieces (Rd1-Re1/ Pd6-Pe6/ Bd8-Be8).

Prizegiving list ended with unusual thematic realization in only 6 moves (minimum). Here are 3 captures by Black: on e6 and d6 because open line for Rg6 + on c3 because pin BPc4/open line for Bd2. Final result: model mate b2-b4#. One important plus in content – dual avoidance at switchback on e5! After all problem deserve special prize.

Two analogical solutions with Black K, R and B as thematic pieces. In both case Black must to capture two White pawns to open line for Be7. So here are thematic switchbacks from different squares between two solutions. Very good meredith.
