Do all systems lose? What about advantage play?

I just like to point out something, and ask a question.

Firstly this section states that all gambling systems are worthless. But what about advantage play? I'm referring to things like visual ballistics and bias analysis.

I'm no spring chicken and I understand the maths of game such as roulette. Specifically that the payouts are fixed, and if there are no change in the odds, then you are going to lose over time. But advantage play is called as such, by casino staff, because a legitimate advantage is obtained by the player.

I have searched the forum for a section related to advantage play, but haven't found one. Am I missing it? I'm interested in sharing information with other advantage players.

Also where is the roulette board here? I run my own roulette forum, but I can see a lot of experienced players, in varied gambling games, are here.

"Systems" generally refer to betting systems. They're all worthless. Sure, Martingale looks good on paper, until...

Advantage Play is different. It means you change your play strategy (and possible bets) according to new conditions that take the game outside of the normal math parameters.

While there are elements that make it seem systematic, AP is not like a system / betting system.

That's my 2¢. Keep the change.

P.S. As far as sharing AP info goes, there was some bru-ha-ha here recently about that sort of thing, so I'd suggest you proceed with caution.
