Originals from The Problemist November 2001

After some time I had enough time to study the new originals from some magazine, this time it was the most recent issue of The Problemist. Well, there is also published the preliminary award of fairies 1996 informal tourney, it will surely be well covered by Christian Poisson's Problemesis. Incidentally, it is Christian who is the judge of 2001 tourney and below you can find some problems that he will have to judge. Of course, the contents is as I saw it, it needn't be complete or precise.

1.Sxd4! th. 2.Sc6+ Se4~ 3.Se5#

It is possible to see now that black kight jumping away closes lines of black lions and thus allows 3 white potential mates Sa3#, Se3#, Sd6#. But white can move his knight d5 only to allow its jump to two of these 3 sqaures. That's why these jumps are possible only after black defences that allow another lion mates by withdrawal. All these defences defend by preparation of antibattery aiming at e5. Main variations:

1...LIh5 2.Sxb5+ Sg5, Sf6, Sd6 3.LIxc1#, Sd6#, Sa3#
1...LIb8 2.Sc2+ Sg5, Sf6, Sd6 3.Se3#, LIf7#, Sa3#
1...LIh8 2.Sf5+ Sg5, Sf6, Sd6 3.Se3#, Sd6#, LIc7#

By variations:
1...Sxf3 2.Sxf3+ S~ 3.Se5#
1...cxd4 2.Rb4+ Kc5 3.LIa3#
1...Rxa1 or c2 2.Sxb5+ S~ 3.Rxc3#

Despite heavy position very good fairy threemover with a strong main idea.

The same mate is reached by two different ways. In set play, white fires double battery, before that the rook is transported to c6 by bishop move. In solution, the mate is given by rook rook move transporting bishop to desired square. Enough use of Circe Parrain, but otherwise too little.

Vladimirov theme. Strange presentation of this paradoxical theme, mixing zugzwang and threat phases. But well, motivation isn't special, it is based mostly on captures.
