Risked, as a wager
I believe the answer is:
staked
'risked as a wager' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for staked that I've seen before include "Bet, wagered" , "At desk (anag.)" , "Wagered with sharp sticks? (6)" , "Wagered or risked" , "Made bet or pierced with stick" .)
