Three asterisked clues need encoding by a Playfair square before entry and three unclued need to be entered likewise. Needless to say the Playfair needs to be derived.
Some very straight forward clues allowed the concentration to be on the end game.
SW encodes to WI meaning SW and I are in the same row or column sequentially (SWI)
IM encodes to LV
LY encodes to NV combined with previous implies I and L in same column/ row as are M and V
RE encodes to LR meaning RE and L are in the same row or column sequentially reversed (ERL)
SWI
ERL
–M
–V
MO encodes to OP meaning MO and P are in the same row or column sequentially MOP – as they are close in the alphabet likely they are in the same row and not in the keyword.
SWI–
ERL–
–MOP
–V–
TH encodes to SO modifying to
SWIT-
ERL–
H-MOP
–V–
Adding in LY to NV gives
SWIT-
ERL-N
—–
H-MOP
–V-Y
A simple leap of faith gives the keyword as SWITZERLAND aided by some subliminal pointers (Geneva) and William (Tell)
S | W | I | T | Z |
E | R | L | A | N |
D | B | C | F | G |
H | K | M | O | P |
Q | U | V | X | Y |
Reverse encoding the title gives EUROPEAN STATES
Column 3 is PORTUGAL encoded on entry to HPAWYBNA
Column 7 is MONTENEGRO encoded on entry to OPAZRENDAK
Column 11 is BULGARIA encoded on entry to KWNCNLTL
Great fun Piccadilly – a lovely implementation of PLAYFAIR. Many thanks and also for the easyish clues, which gave solvers the opportunity to try something a little outside of their comfort zone and I would hope complete their grids.

Agree on the simplicity of the gridfill, but I wasn’t a fan of the Playfair thingymajig as overall the experience was less that of a barred crossword and more that of a Mensa puzzle.
I got to about step 2 or 3 of the above but then got stuck and wasn’t sufficiently motivated to continue – but thank you for the opportunity and the elucidation – I might go back and look up my workings 🙂
