Can flat-betting SD become +EV?

Let's assume H17, RSA. This plays to a 0.15% House Edge off the top.

My understanding is that "House Edge" is not the same as "Average Edge."

The sims I've looked at show this to be a very small negative #, like -0.05% EV. And this # creeps into +$, if the deck Pen is good enough. This is b/c of the gained information of seeing more cards.

Besides deck pen, other considerations would be:
1) Heads-up play VS other players at table
2) Table position. I believe the far left spot would fare better than 1st position, by about +0.10%.
3) One-level count VS multi-level count.]
4) Using a count which divides by denominator of Cards Remaining. The concentration factor changes quickly in Single-Deck.

When you gain information, particularly in Single-Deck, your playing efficiency improves on the 16v10, 12v4, Insurance, etc. The 80/20 rule of thumb I've read says that Net Gain is 80% attritubatable to Bet Ratio changes and 20% to strategy changes.

I don't think I'm crazy to think you can carve out a +$ game on flat-betting SD. Any edge would be small, and you'd have to be betting black chips to make it worthwhile.

I don't have the numbers in front of me, but you would probably need an extremely deeply dealt game to gain a very small advantage.

Part of this is making strategy changes when you have more money on the table. For example, the biggest gain in in the surrender index, where the true count is > 1.4 and you should have a higher bet out, especially since the dealer's ace drops the running count by 1.

Betting black chips will not make it worthwhile. Even though you increase your win-rate with a higher bet, you will also increase your risk of ruin. What do gain if you lose all your money?

My simulations for a single deck, H17, RAS, three players, 60% penetration game using Hi Opt II with full indices (you will need them!) shows an advantage of .231% for flat betting this game. In other words, if you flat bet $100 per hand for this game and played 100 hands per hour, you would make about $23.10 per hour.

I guess you would have to decide if this is worth it for you especially considering the risk to your bankroll, flucuations, etc.

For sure, you need a sizable bankroll and some tolerable for variance.

This was more of a theoretical question. Obviously, you'd like some Bet Ratio > 1:1. But if you had a shop that was intolerant to bet size changes, then this becomes viable. Even a $200 flat bet is not unreasonable for some people.
