James Malcom: The theme is that 5 bishops are fianchettoed-one more than normally allowed! (2020-10-13)
Rainer Staudte: Rules allow a 20-bishops-fianchetto. (2020-10-13)
Henrik Juel: Very nice, James
For this short PG any tester will suffice, but if you push this idea further, Natch is much faster than Jacobi (2020-10-13)
A.Buchanan: Can’t a fianchettoed bishop go round to the bank rank and do it again? So even 20 is not a barrier (2020-10-13)
A.Buchanan: Dates in PDB are yyyy-mm-dd or dd/mm/yyyy. Hence I will change publication date from Dec to Oct (2020-10-13)
James Malcom: Right-the date slipped me again!

Andrew, while a bishop can easily be fianchettoed twice+, about the number of bishops doing it, not how many times it is done. I'm sure that an expert could do 6 fianchettoing bishops. (2020-10-13)
A.Buchanan: I am joking James: this is cool already (2020-10-13)
