Originals from Pat a Mat 27 - first part

Comment on original for solving:
We start with Russian-Ukrainian problem, that should not do any problems to beginners between beginners.

Solution:
1.Sc3! t,
1...Kc5, Kd5, Ke7, c5 2.Dc6, Dc6, Jf5, Dd8#.

Simple with the only plus, it is the airy position (BM). One-phase miniature. (PG)

Then we have a pair from Ukraina with theme called by authors "Veliky-Nedashkovsky theme".

Solution:
1.Db2? Sb3!,
1.Dc3? Sc4!,
1.Dd4? Sd5!,
1.Df6? Se6!,
1.Dg7? Sg7!,
1.Dh8!.

Theme of tries with one threat paradox (1.Dc3? a 1.Dh8!). Authors name this geometrical idea of following white piece by black piece to be "Veliky theme" and popularizes it since 1997 Pula WCCC. The whole combination is named "Veliky-Nedashkosvky idea". (PG) Tries with paradoxal key, but also with motivation typical for German school of E. Zepler times. Good luck for us - they could have worked out Inder theme and baptize it after themselves. (BM)

Now experienced Anatolij with changes and transference of mates.

Solution:
1.Db4? hr. 2.Jb6#, 2.Je3#, 1...Kxd5 2.Dd6#, 1...Vc7!,
1.Jb6? hr. 2.Db4#, 1...Dxd5 2.Jxf5#, 1...axb6!,
1.Ja3? hr. 2.Jb5#, 1...De8, Vb7 2.Jxf5, Se5#, 1...a6!,
1.Sd2? hr. 2.Sc3#, 1...e3!,
1.Je3! hr. 2.Db4#, 1...Dxd5, Kc3 2.Jexf5, Dc5#.

Morephase changes and transferences of mates, but the only internal link lies in the doubtful moving of Qb4 move from threats to key. (PG) I find it sympathetic that in fact existing change of functions of Sb6, Se3, Qb4 moves isn't given in original comment as it appears only as their interversion (in fact #1 in two-move chess), what is less valuable. Personally, I'd like to see also the pin on c4 in try as an addition to pin after 1...Dd5. (BM)

Further there is Valerij, which btw writes very interesting articles about modern twomovers, and here he shows cycle of threat and two mates in three phases.

Solution:
1.b5? hr. 2.Sc6A#, 1...Sxc5, e3 2.Vxc5B, Dxd3C#, 1...Dh6!,
1.Jxd3? hr. 2.Vc5B#, 1...exd3, e6 2.Dxd3C, Sc6A#, 1...e3!,
1.Jxe4! hr. 2.Dxd3C#, 1...Kxe4, Sxe4 2.Sc6A, Vc5B#.

Three-phase cyclical pseudo-le Grand. (PG) Change of functions with high quality and radical changes and mate transferences with valuable motivation. (BM)

Comment on original for solving:
Very high quality, of course, is kept by Vasyl.

Solution:
1.Jxd3? hr. 2.Jb6#, 1...Vxe4, dxe6 2.Dxe4, Vd4#, 1...Ve5!,
1.Dh6? hr. 2.Vd6A#, 1...Vxe4, dxe6 2.Jb6B, Dxe6#, 1...Vf6!,
1.Dc1! hr. 2.Jb6B#, 1...Vxe4, dxe6 2.Vd6A, Dxc6#.

Themes: Zagorujko, le Grand, destruction of battery (4th WCCT, A1), Z-32-26 (author). Good, but I liked 567 more. (BM)

Comment on original for solving:
At last Zoltan, again with changes.

Solution:
1.Jxf6? t, 1...c4(d4), Vb5 2.Jg4, Jd7#, 1...Kxf6!,
1.Je7? t, 1...c4(d4), Vb5 2.Dh2, Jc6#, 1...Kd6!,
1.Jg3! t, 1...c4(d4), Vb5 2.f4, De8#.

Three-phase change of two mates (Zagorujko) with unified defences of Black (diagonal and orthogonal interference of queen). Pity that refutations aren't elegant. (PG) For zugzwang position quite a lot of changed variations, but the cream on cake lies in subtle Zagorujko with strictly kept motive of queen interference. I like works of this kind in long-term competition as I need time to appreciate them fully. (BM)

Comment on original for solving:
Series of threemovers with motto "Miniature melodies" is started by original triple with tries by expert in this genre, Vladimir from the Far East. From there he significantly extends funds of chess composition collections as well as of interesting selections of compositions of known conposers in edition "Our friends".

Solution:
a) 1.Se5! t. Kc5 2.Vb3,

b) 1.Sa7! t. Kc6 2.Se4+,

c) 1.Sf2! t. Kc5 2.Vb3+ etc.
(Dual after 1...Kd4 2.Vf3+ and 2.Sa2.)

Not very impressing triples with unifying keys by darksquared bishop. (KM) Very good a) and c) positions, weaker b), but it must be expected within miniature framework. (BM)

Comment on original for solving:
Big worshipper of S. Loyd, Ukrainian knight and trump Kolja, cooperates in his regional sections in journals even with very known poets and on request from readers publishes co called "crossword compositions". In Ukraina he also fights (still in vain, like against wind-mills but ardously) for his own subjective idea to consider compositions with 9 pieces to be miniatures...

Solution:
1.Kd1! t. Sb2, b3 2.Kxd2+, Vxb3 etc.

Also for miniature really simple and not precise enough. (KM) Poor. (BM)

Comment on original for solving:
See above.

Solution:
1...Kf3 2.0-0#,

1.Jb3! Kf3 2.0-0+ Ke2 3.Ve4#,

1.Jxd3! Kf3 2.Vf1+ Kg2 3.Jf4#.

Complete block miniature with prolonged novostrategical effects of castling rook - thanks to two real phases. (KM) Change of variation with 0-0, undoubtedly more than 571. (BM)
