My works 93 - 98

a) 1.Rxf4=w Rf2 2.Bxc3=w Rb2#
1.Bxf4=w Bd2 2.Rxc3=w Rb3#
b) 1.Rxc3=w Rf3 2.Bxf3=w Bg5#
1.Bxc3=w Be1 2.Rxf4=w Bh4#

Two pairs of analogic solutions but very skinny strategy and poor twinning.

Personal rating: D.

a) 1.Rxh6(Ra1) Rc1 2.Bg3 Bxe3(Sb8)#
b) 1.gxh6(Ra1) Rh1 2.Rg3 Rxc2(Sg8)#

Nice analogy with rich Strict circe motivation.

In this helpmate I again discovered something never seen in works by other authors and impossible in orthodox chess: checkmate by double check with active pin of black piece. Later I published some other works with this theme, this one shows very successful echo diagonal-orthogonal and patrol chess strategy.

Judge Cedric Lytton wrote in the judgement: "Perfect ODT of play with black anticritical moves actively pinning bSf5 (depending on where the wQ is), reciprocal exchange of black 1st/2nd move selfblocks, finally function-exchange by wB/wR in Patrol mates. Attractive, homogeneous and unified, with geometry neatly fitted together, but the (admitteldy inherent) same two black moves, along with the double checkmates, inhibit a higher placing."

Well, I'm ready to accept the argument about repetition of black moves, they are surely a bit boring. But the double checkmates are the core of the problem!!!

1.Ke3 2.Mf2 3.Ke2 4.Kf1 5.Kg2 6.Kg3 7.Kf3 (7.Mg4??) 8.Mg4 Mh4#

Far echo of typical mate - compare to 89.

After long time some my works placed in award of thematical tourney. This one asked for problems with lone king on one side (Rex Solus). Although at the first sight they may seem uninteresting, my future searches proved the opposite.

Köko seems to be extremely suitable for producing helpmate moremovers with very surprising manoeuvres and finales.

Personal rating: C.

1...Mb2 2.Kc4 Mb3#

1.Kd3 Mc4 2.Ke4 Mg3#
1.Kd4 Mc3 2.Ke3 Mg2#

Transmuting rex solus. 2 echo mates, set mate is in fact their diagonal transformation.

Personal rating: C.
