Problem no.762 (Geoff Foster) would have been a good thematic example for this tourney announcement.
Except that problem was H#2,5 and the tourney is for H#2 !
Of course there is the little detail of the length.
But 762 shows very adequately what can be achieved with a Face-to-Face / Back-to-Back twinning.
The theme is “Face-to-Face and/or Back-to-Back”, so I presume that Face-to-Face / Back-to-Back twinning is NOT required?
I understood it as the one of BTB/FTF is enough; and also that it is not necessary for the both pieces in BTB/FTF pair to be neutral, but at least one of them should be.
I believe that absolutely thematic example to this TT might be Igor Kochulov’s problem No.852 which can be shown either with Duplex or with b) Face-to-Face.
