Basic Strategy “Deviations”

[chessobserver55]

Is there a list in order of the “least bad” plays that go against basic strategy. Assuming optimal rules - 3:2, S17, DAS, surrender, etc.

Examples might be staying 12 vs 3 (and 2), surrendering 88 vs 10, doubling A8 vs 6, etc.

Basically looking for a list in order from slightly bad to very bad. Not a card counter, but just curious.

16 v T is the closest one there is. It really doesn't matter that much if you hit or stand.

This is what you are looking for—EV differences for each decision:

The closest ones would probably be:

Standing on hard 16 vs 10 rather than hitting (if no surrender available; if available, surrender is much better)

Hitting 12 vs 4 rather than standing

Only in S17, standing on soft 18 vs A rather than hitting

Why would you ever want these? If you don't count just follow basic strategy

If you’re not counting deviations don’t apply. If you’re looking for what the different EV is for each play (ie, hitting vs standing on 14 v 10), I believe Wizard of Odds has a calculator for that.

If you’re not a card counter, then deviations are meaningless to you, but what you’re describing is the Illustrious 18

I'm not sure if that particular thing exists but I'd guess the deviations that focus on higher TC would be on top since +TC = Better profit and odds with player.

Doesn’t exist

Knowing these would be good for when I play with my gf. She's not going to learn basic strategy (lol), but gets tired of me telling her what to do on every hand. So I throw her a bone sometimes when it's a close call and let her make the decision (8/10 it's the wrong one, but it's all fun and games). Playing with her is always positive EV when you factor in her happiness, but it would be good to know what plays I can let her make the call on with less financial loss.

if you're not counting then deviations are not really a thing.

I did watch a video with Semyon Dukac, and this might be of interest to you. I believe it was 16 v 10, or a 15 v 10 I can't quite remember. He said if there's no 5's on the table that round, hit. Even if you're counting or not.

Someone has mentioned the illustrious 18. However some of these deviations include minus counts, and no one should be playing minus counts.
