2006 and CYCLONE 50-40-30-20-10 years ago

(Text on this page was written by Peter Gvozdják.)

50 years ago (1956)

Refreshing touch to the Lacny cycle - one of the series by Vaclav Pribyl.

40 years ago (1966)

Two black pawns in the difficult Rice cycle.

30 years ago (1976)

Three cyclic plus three non-cyclic changes between two phases. The only Cyclone problem by the author.

20 years ago (1986)

Lacny cycle plus cycle of white 2nd and 3rd moves. Surely one of the very best threemovers ever composed.

10 years ago (1996)

4-fold Kiss cycle was much ahead at the time. Fairy twomover with perfect analogy of lines.

0 years ago (2006)

I do not like to have my name among these famous authors. Fortunately, mine is only one third of the problem, which shows, for the first time, the 5-fold Shedey cycle in a threemover. It took years from the idea to this correct position...
