Section H # 2
Theme: Black on B1 unpins a white piece which one actively sacrifices on W1 without check or capture.

1 Pr V. Nefedov (Russia)

No1

   1) 1. Rxb1! Ba5! 2. ba5 a4 #

   2)   1. Bxa2! Kc5! 2. bc5 Sa3 #

        Harmonious idea in multi-solution form with exact B1, passive Zilahi and model mates.

H # 2 2.1.1.1. (7 + 8)

2 Pr V. Chepizhni (Russia)

No 2

    1)   1. Ke4 Be5   2. Kxe5+ ef4 #

    2)   1. Kc4 Bc3    2. Kxc3+ Rd4 #

        In spite of a certain spottiness of play in phases, the problem makes the bright impression by checks to the white king on B2 and battery mates.

H # 2 2.1.1.1. (7 + 9)

3 Pr E. Navon, M. Witztum (Israel)

No 3

    1)   1. Bg6 (Rh8 - ?) Sc4   2. bc4 Qb8 #

    2)   1. Sg2 (Qg1 - ?) Bd1    2. cd1=R Qf2 #

        Quite complex and tactically saturated idea with antidual unpinning, sacrificing white piece’s leaving the perspective mate-line, line-opening and sweeping play of the white queen.

H # 2 2.1.1.1. (9 + 9)

1 HM I. Antipin (Russia)

No 4

     a)   1. Bd3! (Sc5?) Bc5!    2. bc5 Sd5 #

     b) 1. Sc5! (Bd3?) Sd3!    2. ed3 Bg5 #

       Interesting problem with antidual indirect unpinning, line-opening and active "Zilahi". It is pity that the model mate only in a).

H # 2 b) Ra6<-->Pe2 (8 + 11)

2 HM V. Vinokurov (Russia)

No 5

     a)   1. Rc7 Sg4!    2. hg4 Be5 #

     b)   1. Rb7 Sd5!   2. ed5 Rc6 #

       Tactically saturated and quite complex idea with direct unpinning, black interferences and white line-opening. Rather radical twin.

H # 2 b) Kg3-->c5 (5 + 10)

3 HM V. Chepizhni (Russia)

No 6

     a)   1. Qd1+ Sc1    2. Kxc1 Bf4 #

     b)   1. Qd4+ Sc3    2. Kxc3 Ba5 #

        Light and harmonious half-miniature half-aristocrat with orthogonal-diagonal checks to the white king and model battery mates.

H # 2 b) + bPb3 (4+ 3)

Com M. Witztum, J.Haymann (Israel)

No 7

    1) 1. Bh2 Rd4    2. cd4 Qxb3 #

    2)   1. Be1 Sd3   2. cd3 Qb4 #

       Interesting play with indirect unpinning of white pieces and pin-mates. Heavy construction and two technical white pawns have not allowed to set the problem higher.

H # 2 2.1.1.1. (7 + 14)

Com E. Markov (Russia)

No 8

    a)   1. Qe3 Rd4!    2. Kxd4 Bc3 #

    b) 1. Qh1! (Qf1?) de3   2. Bh4 Rd6+   3. Kg5 ef4 #

        Harmonious and tactically saturated idea with direct antidual unpinning of the white pawn, its frontal and diagonal steps in phases, white line-opening, "follow-my-leather" effect in black's play and model mates.

H # 3 b) Pe7-->e3 (5 + 15)

2 - 3 Pr I. Antipin (Russia)

No 2

     1)  1. Kf6 e4        2. Rf5+ Rf4     3. Rg7 e5 #

     2)  1. c5 Rf3        2. Qf6+ Kd5    3. d3 e4 #

     3)  1. Rf3+ Kc5   2. Kf4 Kxd4    3. Qf5 e3 #

        Triple-phased problem in multi-solution form with chameleon echo model pin-mates.

     2)   1. d4 Qc2     2. Kd5 Sc3+    3. Kc4 b3 #

        Quite harmonious problem with Umnov effect, unusual square vacation for the black king and difficult solutions with unexpected model echo-mates. Hope, authors will forgive the judge some changes of initial position.

H # 3 2.1.1.1.1.1. (5 + 13)

4 - 5 Pr E. Fomichev (Russia)

No 4

    1)   1. Se4 Rxd5+   2. Kxd5 Kxb3    3. Bc5 c4 #

     2)   1. Bc4 Bxd4+   2. Kxd4 Kb2     3. Qe4 c3 #

          Rather homogeneous play with blocking, interferences, active sacrifices of the white pieces and model mates. A few unpleasantly capture on b3.

H # 3 2.1.1.1.1.1. (4 + 11)

4 - 5 Pr V. Vinokurov (Russia)

No 5

     a)   1. Sg4 Re6   2. Re4! d3   3. Bf4 de4 #

      b)   1. Sf5 d6      2. Re5! d4   3. Bg6 de5 #

       Well-constructed problem with line-opening, blocking, direct unpinning of white pawn with perspective sacrifice of the black rook and chameleon echo model mates.

1 HM L. Makaronets, S.Shifrin (Israel)

No 6

    a)   1. Se4 Bb2 2. Bd4 c4+    3. Ke5 ed4 #

     b)   1. Ke4 Rf2   2. Sd5 Bd4   3. Qf3 gf3 #

           Not quite uniform, but very complex problem with unbelievably difficult solutions.

2 - 3 HM I. Antipin (Russia)

No 7

    a)   1. Qc6  f3   2. Sc5 Re4   3. Sg2 c4 #

    b)   1. Ke5 c3   2. Qe6 Rd4   3. Sd2 f4 #

          Nice Meredith with white thematic half-pin play, line-opening, blocking and chameleon echo model mates.

H # 3 b) Pd6-->f6 (4 + 8)

2 - 3 HM L. Makaronets,

L. Lyubashevski (Israel)

        Tactically saturated Meredith, as the previous one, with similar finals.

     3) 1. Ke5 e4 (C)     2. Qa6 g5 (A)    3. Qd6 f4 (B) #

         Triple-phased problem with white pawns moves cycle, blocking and model mates. The strategy, however, is simple and not quite enough original.

H # 3 3.1.1.1.1.1.1. (7 + 6)

4 - 5 HM A. Stepochkin (Russia)

No 10

    a)   1. Bd1 Rf1    2. Ba4 Rb1   3. Bb5 b4 #

    b)   1. Se5 Bh3   2. Sc6 Bf1   3. Sb4 d4 #

       Not quite enough uniform, but rememberring play, ending with model mates. It is pity that thematic white pawn b2 is idle in b).

Com G. Ibulaev (Russia)

No 11

    1)   1. Kf5 f4(A)    2. Sf2 g4(B) +   3. Ke6 f5 #

    2)   1. Kg5 g4(B)  2. Bg2 f4(A) + 3. Kh6 g5 #

        The white thematic half-pin play with reciprocal interchanges between W1 and W2 and model mates.

H # 3 2.1.1.1.1.1. (4 + 12)

Com A. Strebkovs (Latvia)

No 12

1) 1. e1=Q f3 2. Qa1 fg4 3. Qe5 g5 #

2) 1. e1=S f4 2. Sf3+ Kxf1 3. Sg5 hg5 #

Rather heterogeneous, but interesting play with black promotions and model mates by different white pawns on g5.

H # 3 2.1.1.1.1.1. (4 + 15)

Com D. Muller (Germany)

No 13

     1. e6 Sd4   2. Se7 Sb3   3. Sc6 e4 #
