Welcome  To  StrateGems - The  Official  Publication  Of  The  Good  Companions !

Kostas  Prentos - Retros Editor

   I was born on August 28th, 1966, in Thessaloniki Greece. I graduated from the Economic University of Thessaloniki and I work as an accountant. I am not married.

   I learned the moves of chess when I was 12 years old and started playing more seriously at the age of 16. All I could achieve in the tournament arena was the title of FIDE Master in 1995.

   In the last years, I gradually lost interest and gave up tournament chess to concentrate on problem solving and composing. As a result, I was awarded the title of International Solving Master in 2004 and have two GM norms.

   I composed my first problems before the age of 15, but I published my first one much later. Between 1987 and 1991 roughly a dozen of my problems were published. After a long break, I resumed chess composition in 2001. I have published 175 problems in total. Two thirds are proof games; of the rest, orthodox helpmates and fairies hold the biggest share.

   More than half of my published problems are joint compositions. About 130 have been honored so far; 44 among them being prizes. To date, I have 6 entries in the FIDE album (or 4.5 points)

1.Rd8? Sg3 2.Rd3 exd3 3.(Bc2)??

 1.Bf7? Sd2 2.Bc4 bxc4 3.(Rc2)??

1.Bc2? Sd2 2.Bxb3 ?? 3.Rc2 Sxb3#

 Active black sacrifices for square vacation and creation of tempo.

Sacrificing on the wrong square fails each time, due to interfering with the black blocker’s route to c2.

Capturing the white pawn fails each time for lack of a tempo move.
