Participant in chess game’s blunder over pawn (6)
I believe the answer is:
bishop
'pawn' is the definition.
(thesaurus)
'participant in chess game's blunder over' is the wordplay.
I cannot really see how this works, but
'blunder' could be 'bish' (I've seen this before) and 'bish' is found within the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is present in the answer.
'game' could be 'p' (I have seen 'French game ' mean 'p' so perhaps 'game' could also mean 'p') and 'p' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bishop that I've seen before include "one of four beginning on board" , "Senior clergyman" , "Chess piece; mulled wine" , "Powerful cleric" , "Church leader" .)
