Blackjack Basic Strategy Engine

BlackjackInfo is the home of the original Blackjack Basic Strategy Engine, since 1998.

These strategy charts are also applicable to playing blackjack online or live blackjack.

You can also purchase a physical wallet-sized plastic version of the strategy charts here. Or you can try out our strategy trainer which interactively tells you whether you made the correct strategic choice or not.

Once you feel like you’ve memorized the charts, you should also try out our blackjack quiz to put yourself to the test.

How to Use the Strategy Engine

To modify the rules, simply click on the Adjust The Rules button and change from the default options to the exact rules of your casino.

The left hand column represents your hand card values while the very top row represents the dealer’s upcard.

You should also notice the chart is split into 3 segments – Hard Totals, Soft Totals and Pairs. Simply line up the hand you have with the dealer’s up card value and the intersecting value in the chart is the optimal basic strategic choice for these set of rules. Also be mindful that you should never take insurance.

That list is very useful. But the real trick is to learn to variate according to true count. There is no need to learn all the variations according to counting only the most important from true count -2 to + 3. Of course prepare to hear complains at the table from players that play basic strategy exactly and think that is the Bible of Blackjack.

Do you know how many times I have been booed off a table for splitting tens with a high true count? Or how many times the dealer had an upcard if 6 and the cou t was like 2.5 3.2 and the third base guy hits on a 16 making the dealer get 18-20-21 when I had 250 in the hand only to loose standing with 12. I see a lot of people on here talking about all this theory. And that’s great but there is a lot of things you can’t be taught. I think this is the primary… Read more »

What’s the difference between early and late surrender?

Early surrender is vs a dealer T or A *before* they check for blackjack — extremely valuable.
Late surrender is *after* they check.

Chart is instructing playing to stand on 7,7 vs the dealers 10???? I don’t see how this can be correct? Is it?

Its correct… because 2 of the cards that can help you, you already have in your hand.

Nice engine. It’s good to see the deviations from standard basic strategy chart that are on the Google because those charts (Google) created for 2 decks and no surrender option. I prefer the options not to split 88 against TT and AA, and not to split AA against AA but hit Aces.

Thanks
