- The noun 'a bet' is not always 'ставка'; in 'Your best bet is...' it means 'лучший вариант'.
- 'You bet!' as an interjection means 'Конечно!' or 'Ещё бы!', not an invitation to gamble.
Common Mistakes
- Using 'betted' as past tense (correct: 'bet').
- Using 'bet for' instead of 'bet on'.
- Overusing the literal meaning when the figurative is intended.
