punts

I'm a little stuck... Click here to teach me more about this clue!

'gambles' is the definition.
(I know this)

I don't understand how the rest of the clue works.

(Other definitions for punts that I've seen before include "kicks" , "Stakes" , "Flat-bottomed boats" , "river-craft" , "bets" .)

I've seen this clue in The Globe and Mail.
