Gerardus Hendrik Goethart (04-09-1892 - 17-05-1969) Dutch composer
Gerardus Goethart was mostly a twomover composer.
24 of his problems were compiled by Max Niemeijer in "
Chess Problems of G.H. Goethart" (1962).
He left his name to the following theme, also called "Goethart unpin": White unpins a black piece, taking advantage of an interference of this pinned black piece by another black unit.
Here is a good training for the twomover round of the
coming WCSC:

Jean-Luc Seret
[Kevin Spraggett's blog [broken link] ] |
Jean-Luc Seret is a French o.t.b. IM and was four times o.t.b French champion, but what interests us is his contribution to chess problems.
He was a friend of
Jean-Michel Trillon's (they worked for the same company) and they composed a few problems together. He is interested in problems with retro contents (with fairy conditions Volages or Sentinelles Angevines) or in moremovers or studies.

Show Solution1.Kb2? is the main plan threatening 2.Bxa4# but 1...a3+ disrupts this plan.
White could try 1.Bxa4+? Kc1 2.Rc4+ Kb1 3.Bc2+ Kc1 4.Bf5+ Kd1 5.Bg4+ Ke1 6.Re4+ Kf1 7.Bh3+ Kg1 8.Rg4+ Kh1 9.Bg2+ Kg1 10.Bc6+ Kf1 11.Bb5+ Ke1 12.Re4+ Kd1 13.Kb2 Rxc5 14.Ba4+ Rc2+ 25.Bxc2# but 3...Ka1! 4.Kb3 b5! 5.cxb6 e.p. Rb5+!
This is why both pawns a4 and b7 must be eliminated:
1.Be2+! Ke1 2.Bg4+ Kf1 3.Bh3+ Kg1 4.Rg4+ Kh1 5.Bg2+ Kg1 6.Bxb7+ Kf1 7.Ba6+ Ke1 8.Re4+ Kd1 9.Be2+ Ke1 10.Bb5+ Kd1 11.Bxa4+ Kc1 12.Rc4+ Kb1 13.Bc2+ Kc1 14.Bf5+ Kd1 15.Bg4+ Ke1 16.Re4+ Kf1 17.Bh3+ Kg1 18.Rg4+ Kh1 19.Bg2+ Kg1 20.Bc6+ Kf1 21.Bb5+ Ke1 22.Re4+ Kd1 23.Kb2 Rxc5 24.Ba4+ Rc2+ 25.Bxc2#
