Insurance & even money
"Could you please explain that topic [even money] to me and explain a little on insurance."
Insurance is a side bet offered when the dealer has an ace up. You are allowed to bet up to half of your original bet that the dealer has a 10 valued card in the hole. If the dealer has a ten value card in the hole, you are paid 2-1 on the winning insurance side bet, but of course you lose the original bet which means you breakeven overall on the hand (unless you have a blackjack too, which takes us to the even money offer outlined below). If the dealer doesn't have a 10 valued card in the hole, the player loses the insurance side bet and the hand is played out to determine the outcome of the original bet.
An even money offer on a player blackjack vs a dealer ace up is the same as taking insurance in the full 1/2 of the original bet amount allowed. If you were to take insurance and the dealer has blackjack, you push the original bet and win 2-1 on the insurance side bet, winning a net amount equal to your original bet. In the same senario but the dealer doesn't have blackjack, you lose the insurance side bet of 1/2 the original bet, but win 1 1/2 times the original bet for the blackjack, again winning a net amount on the hand equal to the original bet.
