Side by side

£1 on the main hand and £1 on perfect pairs for 60 hands: the main bet costs about 30p on average; the side bet about £3.

Insurance and even money

Insurance is a separate bet that the dealer has a ten underneath. "Even money" on your blackjack is the same bet in disguise. Decline both.
