A couple of chips, maybe (3)
I believe the answer is:
bet
'a couple of chips maybe' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bet that I've seen before include "Wager, speculate" , "Speculation" , "22 across will accept one" , "'Stake, wager (3)'" , "Money risked on a gamble" .)
