Take risks; bet (6)
I believe the answer is:
gamble
This clue is a double definition.
'take risks' is the first definition.
(I've seen this before)
'bet' is the second definition.
(I know that bet can be written as gamble)
(Other definitions for gamble that I've seen before include "Bet money" , "Risky enterprise" , "Bet; risky undertaking" , "Make a bet" , "Run a risk" .)
