3,3 ≠ 21

Eureka! Earlier I posted a single-deck index of 0. Gramazeka's sims show a TC os 4.7 for shoe games. It's because the pair of 3's robs the dealer of the opportunity to make 21. tthree posted that a side count of 7,8 would be valuable. I thought so too, but it appears 2's & 3's are more important to the dealer.
You are looking for the double-deck index. In 1D 50% of 3's are gone, 2D "only" 25%, as opposed to 2/32 or 6.25% in an 8D shoe game. I propose a TC of +1 for double-deck games, though I have no math to back that up. A positive TC in Hi-Lo should have fewer 2's and 3's.
I've been considering this question, BJMath, in addition to your CV simulations with varying results including negative numbers for a TC. I see this as similar to 7,7 vs. 10 in single-deck games.

Uh, you might want to rethink that. How do taking 3's rob the dealer of the opportunity make 21 unless it's a game where the dealer hits hard 18 (which I've never heard of before)?

Good observation. In shoe games hit 3,3 vs. 8 since your max bet is out & splitting is risky towards your BR. The player's advantage for this hand is about -23, you wanna minimize losses. You will likely bust one or both & the dealer rarely busts 8.
A 3 would only help if it's in the hole, the dealer wouldn't hit a hard 18. This hand does not provide much in strategy deviation. I may be wrong, but splitting this hand is only relevant in single and double deckers with an average sized bet out. The Omega II count i use doesn't even have indices for this hand, always hit 3,3 vs. 8.

Dealer 8 up + 3 in hole = 11. 11 + 10 = 21. If the count is high and you have 3-3 the chances for the dealer to also have a 3 in the hole is much lower than normal in a high count there are, on average, a normal amount of medium cards and a higher amount of big cards so you have a better chance of splitting 3-3 and winding up with hands stronger than 18 than if you'd just hit your 6.

Actually you have a good chance of busting out both hands rather than just busting out one.
