Brian Stephenson 50 C 25.9.2004

To celebrate birthday of the composer, a jubilee tourney is announced in 2 sections.

Section 1

Theme: orthodox #4, free theme.

Judge: Jörg Kuhlmann.

Examples: by jubilee, by judge.

Section 2

Theme: fairy direct-, help-, reflex-, self-mates using any of 4 basic chinese pieces (leo, pao, vao, mao) with free theme (other fairy pieces or conditions are not allowed).

Judge: Torsten Linß.

Examples: by jubilee No 1, by jubilee No 2 by judge No 1, by judge No 2. However jubilee is trying to popularise chinese pieces for a long time, no wonder there are already some his problems published at CCM: (Look at some other problems featuring chinese pieces from fairy elements index on the left side of the main CCM page.)

Entries should be sent before September 25th 2004 to the adress

1st HM Suomen Tehtäväniekat 1997

1.Kf2? th. 2.Rd4#
1...c5!

1.Sd7! th. 2.Sc5, Sd2#
1...Bxd7 2.Rc6! th. 3.Rc4#
2...Bxc6 3.Kf2! th. 4.Rd4#
3...e5 4.Sd2#

Logical problem showing Dresden theme - the try is refuted by move op pc7 (unit A), by means of preliminary plan Be6 (unit B) is forced to switch the place to c6 and thus "sufficient" defence after Kf2 attack is replaced by "insufficent" one by pe7 (unit C). This form of Dresden is called "Wechselform" in German. (Isn't it?)









#4 (10+8)

Phénix 1988

1.Sxb6? th. 2.Sc4, 2.Sd5
1...h1B!

1.e7! th. 2.e8Q! th. 3.Qe2#
1...h1S 2.Sxb6! th. 3.Sc4, 3.Sd5

Another logical problem. The try is refuted by bishop promotion with stalemate motivation. That's why White changes the order of his plans, threats queen promotion and forces knight promotion by Black (avoiding bishop one). A problem full of promotions!

3rd HM British Chess Magazine 1978

1.Kxf6! th. 2.VAxd7#
1...LExb2+ 2.PAcc5#
1...LEf1+ 2.VAc5#
1...LExc6+ 2.Sc5#
1...PAd6+ 2.Sxc7#
1...PAde7 2.Sd4#

White in a key by King unpins wVA and provokes no less than 4 checks. However these by bLE unguard wPAd5 and allow antibattery mates by hurdles causing the check to wK. 3 mates on c5 by different pieces ...









#2 (12+12)
0+1 leo, 2+2 pao (c3), 2+2 vao (f2)

1.Rc7! th. 2.LEc6#
1...LEd4 2.LExg8#
1...MAfd4 2.LEf7#
1...MAed4 2.LEe6#
1...d4 2.Bxg8#

... and here even 4 defences on d4. 3 of them, by chinese units are pure anti-Somov defences (closing line MAd3-d4-c5 in anticipation of closing the c7-c6-c5 in threat, theme A), however they all immobilise pd5 and also unguard one of squares for leo mate. Good chinese strategy.









#2 (7+11)
1+1 leo, 0+2 pao, 1+2 mao

Die Schwalbe 1991

Black starts: 1.LEc3 PAh4 2.Kd4 MAg4#

White starts: 1.PAc4 LEf8 2.Kc5 MAe7#

Interesting chinese duplex has analogical play - 1st halfmove blocks (but PAc4 also unguards f8-c5) 2nd halfmove sets chinese piece line, 3rd halfmove is Umnov move by mated king and 4th move is model antibattery mate.









h#2 (4+5)
0+1 leo, 1+0 pao, 1+1 mao
duplex

2nd-3rd Prize e.a. Phénix 1996

1.Rc2 PAc3 2.Se7 VAb3 3.Bd7 Sc4#

1.Bh3 VAg4 2.Sc7 PAg5 3.Rc6 Sf5#

Great analogy in echo diagonal-orthogonal. Especially attractive are bicolour Bristols of orthodox and chinese pieces, and double indirect antibattery mates.









h#3 (5+6)
1+1 pao, 1+0 vao
2.1.1.1.1.1
