From the TT Director Aleksey Oganesjan I received 7 anonymous problems. The problems No 4 (Kd1 Ka2), 5 (Kc1-Kh1), 6 (Kd4-Kh7) and 7 (Kf1-Kd8) are non-thematic because there are no reflex defenses at all.
I was hoping that more problems will be composed but at the end three thematic problems were composed. All three remaining problems are of very high quality and I believe that all three problems will be selected for FIDE Album. I did enjoy analyzing them. Excellent content in all of them.
In all problems I found few constructional improvements and I gave my recommendations for improvements. If authors accept them I recommend publishing new versions in final award. I decided to rank problems this way:

1st Prize, 1st Place - No 1, Evgeni Bourd (Israel)

1.S5xf3? [A] – 2.Kg2 h1Q#, 1...Ba6! 2.Qxc6#
1.S4xf3? [B] – 2.Kg2 h1Q#, 1...b4! 2.Qc4#
1.Qxf3+? [C] Kc5! 2.Se6#
1.Qe3? – 2.S5xf3/S4xf3, 1...Qxf6!
 2.Qxf3+ ~/Qxf3+ 3.Kg2/Rfg2 h1Q/Rb1#
1.a4? – 2.Qxf3+ Kc5 3.Kg2 h1Q#
 1...Sb4/Rb4 2.S5xf3/S4xf3, 1...b4!
1.a6! – 2.Qxf3+ [C] Kc5 3.Kg2 h1Q#
1...Qb6/Sb6 2.S5xf3 [A] / S4xf3 [B] etc.
Without any doubt the best problem so far composed showing this theme. For the first time two pairs of thematic defenses are shown (in try and solution). The main goal of white is to capture bPf3 to allow Kg2 and h1Q#. Captures by white knights are failing due to mates by wQ after reflex defenses. The try by queen is failing due to another reflex defense 1...Kc5 2.Se6#.
So white tries to destroy checkmate 2.Se6# by giving flights to bK (b4 & b6). The try 1.a4 is defeated by selfblock 1..b4. In both try and solution there are selfblock defenses that are defending one of thematic mates (Qc6 & Qc4) so one of the knights can capture bPf3.
There is an additional beautiful try 1.Qe3? where two thematic variations are threats and threat from solution is variation. Excellent addition to the content. Real masterpiece.

2nd Prize, 2nd Place - No 3, Evgeni Bourd (Israel)

1.Qg5? – 2.Qxh5 Rxh5#, 1...Bxc5! 2.Sf6#
1.Sg3? – 2.Sxh5 Rxh5#, 1...Rc4! 2.Be4#
1.Sf6+? Kxc5 2.Sxh5 Qxh5#, 1...Kxe5! 2.Qc7,Qd6#
1.Re8! – 2.Sf6+ ~ 3.Sxh5 Rxh5#
1...Rb4 (2.Sf6+? Kxe5 3.Bd6#) 2.Qg5 ~/h4 3.Qxh5/Qxh4 Rxh5/Rxh4#
(2.Sf6+? Kxe5 3.Qxd4#) 2.Sg3 ~ 3.Sxh5 Rxh5#
Another great problem. The goal of white is to capture bPh5 to allow Rh5#. Two thematic tries are failing due to selfblock defenses. In solution Grimshaw defenses on b4 are allowing thematic tries. And it’s almost like double Grimshaw because both thematic defenses are containing useful and harmful effects. After the solution selfblocks are prevented by interception and that’s why white thematic variations are possible. Great idea but there are few constructional defects. WRf8 is underused. It’s only used in solution and to prevent several cooks. There are very unpleasant multiple duals in thematic variation: 1.Re8 Bb4 2.Sg3 h4 3.Q~/Re7 hxg3#. They could be avoided by adding bPg5 (this way h4 would not be defense because black moves that are threating direct mates are not considered as defenses). Also bQh1 is underused (it only blocks h1 so that bR cannot play to this square).

3rd Prize, 3rd Place - No 2, Evgeni Bourd (Israel)

1.Rd5? – 2.Se1 Sc3#, 1...Sd6 2.Se5#
1.Rd4? – 2.Se1 Sc3#, 1...b5 2.Sb4#
1.f5! – 2.Bxd7+ ~ 3.Se1 Sc3#
(2.Bxd7+? Kd6 3.Rd5#) 2.Rd5 ~/Se~+ 3.Se1/Ke1 Sc3/Qe2#
(2.Bxd7+? Kd6 3.Rd5#) 2.Rd4 ~/Se~+ 3.Se1/Ke1 Sc3/Qe2#
The goal of white is to play Se1 that will force Sc3#. However wSd3 is pinned. Two tries by rooks are failing by reflex defenses. The keymove 1.f5! is cutting line g4-d7 so 2.Bxd7+! is threat. Now there are two thematic defenses that will unguard d6 square. Now one of the try moves are available because reflex defenses are eliminated. Very nice problem.
