Mihailo Stojnić 1.Pr Mat Plus 1998/99
|
1st Prize: No.433 by Mihajlo Stojnic (Yugoslavia). Although there are hundreds of problems showing reciprocal changes on white second move this exceptional problem fully deserves 1st prize. I think that this is very original mechanism in combination with corrective play by BS. Excellent key with a quite threat. 1... S~ 2.Sf6:+ Kf4: 3.Qd4:#, 1... Sf4: 2.Re3+ de3,Kd5 3.Sf6:,Qa2#, (1... b5 2.Sd7: ~,S~,Sf4: 3.Sc5,Sdf6:,Shf6:#); 1.Qa2! ~ 2.Qc4 ~,Se3 3.Qd3,Re3:#, 1... S~ 2.Re3+ de3 3.Qc4#, 1... Sf4: 2.Sf6:+ Ke5 3.Sbd7:#, (1... b5 2.Sd7:). |
Mirko Marković 2.Pr Mat Plus 1998/99
|
2nd Prize: No.524 by Mirko Markovic (Yugoslavia). Three changed variations between try and solution. Excellent construction and very nice play. Nice refutation that is self-blocking the flight given by the try move. Very attractive open position where there is only one piece around BK. 1.Bb7? ~ 2.Sd8+ Kd4 3.Se6#, 1... Ke6 2.Sd4+ Kf6 3.Qe7#, 1... Qf5 2.Se5+ Kd4,Ke6 3.Qc5,Qe7/Qd6#, 1... Qe5 2.Qe5:+ Kc4 3.Sa5#, (1... Kc4 2.Qf4+ Kb3/Kc3/Kb5,Kd5 3.Qb4,Sd8#), (1... Ke4 2.Sd8+ Kf5 3.Qf4#), 1... Sc4!; 1.Qf4! ~ 2.Se7+ Ke6 3.Bc8#, 1... Ke6 2.Bc8+ Kd5 3.Se7#, 1... Qf5 2.Qd4+ Kc6:,Ke6 3.Qd6,Sd8#, 1... Qe5 2.Qe5:+ Kc6: 3.Qd6#, (1... Qg5 2.Qf3+ Ke6 3.Bc8#). |
Valeri M. Shavyrin 3.Pr Mat Plus 1998/99
|
3rd Prize: No. 431 by Valeri M. Shavyrin (Russia). Cyclic (3-fold) play on the white second move in combination with a corrective self-blocking black promotions. There is also dual avoidance on white second move. Very complex mechanism. 1.Qg1? ~ 2.Bb4+ Kd3/ab4 3.Rd6#, 1... Sf1!; 1.Bc7! ~ 2.Ba5:+(A) Kd3 3.Rd6#(B), 1... e1~(QRB) 2.Rd6+(B) [2.Bb5?] Ke2 3.Bb5#(C) [3... Ke1??], 1... e1S! 2.Bb5(C) [2.Rd6?] ~ 3.Ba5:#(A), 2... Sd3 3.Sc4# [3...Kd3??], 1... Ke1 2.Qg1+ Kd2,Sf1 3.Rd6,Ba5:#. |
Miroslav Subotić 1.HM Mat Plus 1998/99
|
1st Hon. Mention: No.423 by Miroslav Subotic (Yugoslavia). Great achievement in a "Meredith" position. Three nice tries followed by two Indian variation in solution. Nice flight giving tries. 1.Be4? (~) 1... de5 2.Ke6: Ke4: 3.Rc4#, 1... Ke4: 2.Rc4+ Kd5 3.Se3#, 2... Kf5 3.Se3#, 1... d5!; 1.Be7? (~) 1... d5 2.Kg6 Ke5: 3.Bf6#, 1... de5 2.Ke6: e4 3.Bf6#, 1... Ke5:!; 1.Bg7? (~) d5!; 1.Bh8!

Mircea Manolescu 2.HM Mat Plus 1998/99

2nd Hon. Mention: No. 425 by Mircea Manolescu (Romania). Dual avoidance in combination with 5th WCCT theme. Good economical setting. 1.Qe3! ~/Kd6 2.Qd3+ Kc5 3.Be3#, 1... Rbd7 2.Be4+ Kd6 3.Sc4#, 1... Rfd7 2.Ba2+ Kd6 3.Se4#, (1... e4 2.Bb2 ~ 3.Qd4#). |
Zoran Gavrilovski Com. Mat Plus 1998/99
|
Com.: No.434 by Zoran Gavrilovski (Macedonia). Nice problem with a lot of variations. But several variations are very rude (capturing of black pieces). 1.Sg4! ~ 2.Be3: ~,fe3,Rd4: 3.Sf2,Re3:,Qd4:#, 1... Rd4: 2.Re3:+ fe3 3.Qd4:#, 1... Bd4: 2.Bd5:+ Sd5: 3.Qd4:#, 1...

Victor Melnichenko Com. Mat Plus 1998/99
|
Com.: No.426 by Victor Melnichenko (Ukraine). Half-battery and black corrections by pawn promotions. However one of the thematic defenses (1f1Q) is not changing second white move and it does cut down a value of this otherwise good problem. 1.Kh3! e4(~) 2.Sf3+ ef3 3.Rc1#, 2... Kf1 3.Sbd2#; 1... f1QRB 2.Sf3+ Qf3: 3.Rf3:#, 2... Kf2 3.Bb6#; 1... f1S 2.Rf3 ~ 3.Sf1:#, 2... Sd2: 3.Bd2:#; (1.Rg3:? f1S!). |
Vyacheslav Kamenskiy Com. Mat Plus 1998/99
|
Com.: No.420 by Vyacheslav Kamenskiy (Russia). Very nice key that gives additional two flights to BK. I hope that this is an original scheme. Its not very common that problem with only 5 pieces contains 4 variations. 1.Rg2! (~) 1... Kd4 2.Rg3 Ke4 3.Qc4#, 1... Ke3 2.Ke5 Kf3 3.Qe2#, 1... Kf3 2.Qe2+ Kf4 3.Rg4#, 1... Kf4 2.Qb3 Ke4 3.Rg4#. |
Borislav Ilinčić Com. Mat Plus 1998/99
|
Com.: No.523 by Borislav Ilincic (Yugoslavia). Nice key that gives two flights to BK but variations are very simple and not very interesting. 1.Qg6! (~) 1... Kf4 2.Rd6: Ke3,Kg4:,Ke5,e~ 3.Qe4,Rd4,Sd3,Qe4#, 1... Kd4 2.Qe4+ Kc3,Kc5: 3.Qd3,Rc6:#, 1... Kd5 2.Qe4+ Kc5: 3.Rc6:#, 1... e6 2.Qe4+ Se4: 3.Sd3#. |
Joza Tucakov Com. Mat Plus 1998/99
|
Com.: No.522 by Joza Tucakov (Yugoslavia). Interesting rex-solus with several pawn batteries. 1.Se2! ~ 2.d5+ Kf5 3.c4#, 1... Ke6 2.c4 Kf6,Kd6: 3.d5,Ra6#, 1... Kf5 2.d5 Ke4 3.c4#. |
