The Problemist (and some Greek composers)

The chess magazine The Problemist is issued by the British Chess Problem Society (BCPS, www.theproblemist.org/) since many decades and it has earned world wide recognition.
I have recently received the issue [The Problemist, Volume 24, No 1, January 2013] which has 48 pages and a supplement [The Problemist Supplement, Issue 122, January 2013] with 12 pages. The variety of the subjects is huge and it covers every genre of the chess composition.

Here we present Greek composers' problems, which are mentioned or published in this issue.

Problem-703
Kostas Prentos
First Prize ex aequo, Bulgarian Wine Ty Kobe 2012

6Br/1pp4s/1R1B4/3S4/pp2k3/5p2/8/1r2bKs1 (5 + 11)
hs#3, Anti-Take and Make, Help-self-mate three-mover
b) -bSg1 (Twin without the black Knight of g1)
a) 1.Be5 cxb6(Rg6) 2.Bxh7(Sf6) Sg8 3.Rg2+ fxg2(Rg6)#
b) 1.Se3 Rxg8(Bc4) 2.Rxb4(b3) b5 3.Be2+ fxe2(Bc4)#

In (Take and Make) the capturing piece continues playing a move. In Anti-(Take and Make) the captured piece makes a move.
In the Help-self-mate the White plays first and cooperates with the Black to bring him to a mate position, but then the Black reacts by giving mate.

Reciprocal batteries.

Marine pieces

As you know, in chess composition the composers invent various pieces, which move or capture in various ways.
The IGM Petko Petkov from Bulgaria has written three articles for a group of pieces which have Marine names, and they are published in the site Julia's Fairies by Julia Vysotska from Latvia.

1) Part I – Siren, Triton, Nereid

2) Part II – Poseidon, Marine Knight, Marine Pawn

3) Part III – Scylla, Charybdis
