JF Original Problems | November, 2020(2)

The judge of JF-2020/II: Hans Gruber.
The judge of Retro & PG problems 2019-2020: Vlaicu Crișan

Coming soon: nobody in the waiting list…

  • (30.11) No.1564 (hs#4) János Csák (Hungary) & Aleksey Oganesjan (Russia). Attractive sacrifices lead to ODT “model checks” and model mates.
  • (28.11) No.1563 (h#4 ; Grasshopper) Niels Danstrup (Denmark). An interesting coincidence about the numbers: the previous problem by Niels was No.1553 on the date 28.10!
  • (26.11) No.1562 (h#4 ; Functionary Chess) Oleg Paradzinskij (Ukraine). Warm welcome to Oleg!
  • (24.11) No.1561 (h#2 ; HurdleColourChanging pieces, Lion, Rook-Lion, Rose-Lion) Michal Dragoun (Czech Republic). The problem is not computer-tested – I found firstly geometrical pattern and then I discovered, that neither Popeye nor WinChloe are able to test Andernach roselion…(Author). Important to note two different names for the same property: Andernach hoppers = HurdleColourChanging pieces.

Animated diagrams use Py2Web by Dmitri Turevski and WinChloe‘s graphics, Christian Poisson
