Problems 410 & 411: Nikola Predrag - Helpmate

nikola(19.06.2014) We present two more helpmates from Nikola Predrag.  He has used another unusual twinning to show lengthy double rundlaufs. In these problems also the twinning happens after the mating position of each previous solution.  (I have used the symbol "#>"  to indicate that the change of twin happens after the previous mating position).

Two ten-step Rundlaufs:

Bl.bishop: b2-a3-c5-e7-d8-g5-h6-f4-h2-e5-h2.

W.Pawn:/Q: d3-d4-d5-d6-d7-d8-f6-h4-e1-g3-d3. (Author)

The length of the Rundlauf makes the task, also the consistency of the twinning without any superflous white officer in any of the phases. The captureless play ensures that only the BK, WP/Q changes position during the play enabling the return to the start position (Author)  

The next problem shows even longer Rundlaufs. The twinning is not consistent at twin (g), but worthwhile considering the length of the round-trip !. (Seetharaman)

Two more unusual chess performances from Nikola showing the synergy of logic and strategy! Who knows, maybe the concept of continued problem will became a popular type of Helpmates Of The Future?

More popular is the removal of white mating piece. Using that Bala did some years ago a nice problem showing a short rundlauf. Nikola is taking the theme to great heights with this more unusual twinning. Well done Nikola!

Last year the theme in Matreshka tourney (WCCC Kobe) was also for interesting twin form - the twin is created after change of colour of the mating piece in the mating position.
Here is the bulletin with the award:

This Matreshka award, the Bala's gem and the award at bstephen.me.uk/.../... ,
show very interesting potential of the "Continued Play" twinning.
