Variance and fluctuate reduction

[seriousplayer]

Are there any possible way to reduce negative variances and fluctuations in blackjack? Especially with games with high house edge.

Backcount, wongout, don't make high-variance decisions (doubling Soft-20/21 vs 6, lucky ladies side bet, promo hunt the 7-7-7 of diamonds for $200,000 [or w/e makes the game barely +EV], etc.).

But yeah, you shouldn't be playing games with high HE's, and if that's all you got, backcount. Most don't play any game with an HE > 0.50%.

Most don't play any game with an HE > 0.50%.

I play a BJ game with a HE > 0.5% and a SCORE > 100.

In addition to what was already said:
Slowing the betting ramp will reduce variance, but will also reduce EV (sometimes not as much as you might think).
More indices will reduce variance.
A more accurate count will reduce variance.
Perfect hole card information will reduce variance, and increase EV.

Betting the same amount on every hand reduces variance. Not doubling down or splitting reduces variance. Obviously these aren't choices that would work for you. What you're talking about is reducing variance in blackjack relative to your expectation and that means playing games with a higher SCORE. That means shopping for better rules and especially for better deck penetration. You will get bigger edges and your EV will outrace variance sooner.
