687 Pat a Mat 28 - March 2000

Comment on original for solving:
Givi works with threat paradoxes, ...

Solution:
1.Kg6? hr. 2.Sf3C#, 1...Jd3a!, 1...Je6b!
1.g3? hr. 2.Jg5A#, 1...Je6b 2.Sf3C#, 1...Jd3a!

1.Jd5! hr. 2.Jf6#
1...Jd3a, Je6b, Kxd5 2.Ve3B, Jg5A, Sf3C#

Cyclic form of Ruchlis and Dombrovskis themes (author). Additional comment by JL: I really can't understand how the Dombrovskis theme can be cyclical. As far as I see, here is no cycle. Of course, it doesn't mean that the composition is automatically poor!

Praha, CZE & Velky Kyr, SVK
690 Pat a Mat 28 - March 2000

Comment on original for solving:
Threemover 690 is Czechoslovak not only according to the areas from which authors come from, but also by content. Third (Bohemian) pure mate isn't present due to lack of inventive energy caused by presence of one very complicated strategical variation (from Slovakia).

Solution:
1...Vf1+ 2.Dxf1#
1.Dg6! zz
bxa5, Kc4, b5 2.Jxf5, Dxf5, Dxd6+

Missing third mate for canonical form or the "bit" delayed polemic with canons? Btw, how would look the threemover developement is Bohemian school demanded only two model mates? (KM)









#3 (8+8)

Ladislav Polacek
Bratislava, SVK
691 Pat a Mat 28 - March 2000

Comment on original for solving:
Mr. Ladislav really forced the computer of Ivan Jarolin to work hard, finally he got correct position of 691 with classical branching of variations.

Solution:
1.Vd1!
hr., Vxh4, f4, Sa4, b5 2.Sxc4, Dxg5+, Dxh5, Jxf5+, Dg7

Nice silent threat allows rich subvariant branching pointed by preparation of "far" mates by white queen. (KM)









#3 (8+10)

Karol Mlynka
Bratislava, SVK
692 Pat a Mat 28 - March 2000

Comment on original for solving:
Finally the next "pulling" of twomover to modern variation from of threemover, but again with "not very strong" assistance of promoted rook. It should be also a sign for authors that our stack of threemover is exhausted.

Solution:
1.Dh7! hr. (Sd4) 2.Dxc2+ a hr. (Sg6) 2.Se2+
1...Sh5+ 2.Dxh5 (hr. 3.Kf2#)
2...Sxg3, Sd4, Jd3, Kxe1, Jc3 3.Kxg3, Kf4, Ke3, Dh1, Vxc1#, - cross of white king
1...Sb5 2.Jd3! (hr. 3.Dh1#)
2...Sxg3, Sd4, Jxd3, Sc3 3.Jb2, Ve1, Dxd3, Jf2# (2.Dh5? Sxc4!) - trial avoidance

Z-24-58. Despite use of promoted piece the double threat remained, but it didn't in fact disturb me (author - KM).









#3 (11+10)

Ralf Krätschmer
Neckargemünd, D
693 Pat a Mat 28 - March 2000

Comment on original for solving:
In the logical sevenmover 693 isn't good 1.cxd4+ Kxd4 2.Sf6+ Kxc5 3.d5+ exd3! First it is necessary to remove Pe4.

Solution:
1.cxd4+? Kxd4 2.Sf6+ Kxc5 3.d5+ exd3 e.p.!
White in preparation plan removes bpe4:
1.Sf8! Kf6 2.Jxe4+ Ke5 3.Jc5 Kf6 4.Se7+ Ke5 and now 5.cxd4+ Kxd4 6.Sf6+ Kxc5 7.d4#

Classical logical one-variation moremover. (IG)
