Here are the top 5 costly blackjack mistakes along with some blackjack tips.

Splitting Tens or pair of 10s

Splitting a pair of 10s is a horrible play to watch someone do but this is a frequent mistake at the blackjack table that is costly.

A pair of tens means you already have 20 and this will beat most dealer hands. The reason why players make the wrong play is because they are chasing the possibility of getting 2 blackjacks or hitting another set of tens.

Not only is splitting 10s the wrong play but these players that make this mistake now have 2 more chances of making more mistakes with more money on the line. 

blackjack tip #1: any hard 17, 18, 19 or 20 should always stand.

Player 10 versus dealer 2 through 9

If you said to hit then you have made the incorrect play. This is an obvious double down opportunity that many players won't make for 2 bad reasons, feeling unlucky or not wanting to risk more money and to take the safe approach.

When you run these hands through a million simulations you will find the correct answer is to double down and this gains the most amount of money on average for the player.

blackjack tip #2: Always double down player 11 versus dealer 2 through 10, double down player 10 versus dealer 2 through 9 and double down player 9 versus dealer 3 through 6.

Player Ace 6 versus dealer 6

If you answered stand or hit then you made the incorrect answer. Double down this hand without hesitation as this is pure expected value. Although hit or stand are incorrect players, stand is actually going to cost you the most money.

blackjack tip #3: always double down player Ace 6 versus dealer 2 through 6

Splitting Eights or pair of 8s

When a player gets a pair of 8s they usually freeze like a deer in headlights and we don't blame them as the statistical analysis of the options will reveal that splitting is the correct play against dealer 2 through 10 and that a hit, stand or double down are all incorrect plays.

blackjack tip #4: always split your 8s no matter what the dealer has

Pair of fives

Do you want to know the worst thing you can do to a pair of 5s against a dealer 6? Split. Why do players do this consistently will remain one of those unsolved mysteries but it is just a fact of life. A pair of fives should be treated like a player 10. Having a player 5 to start any hand is already a bad hand to be dealt so splitting 5s is just going to turn a good hand into a bad one.

blackjack tip #5: Treat pair of 5s like a player 10 and you double down against dealer 2 through 9.
