It´s like trying to beat the index of a stock exchange: Some people manage to do it over a few years but they won´t be able to do it assuming long time horizons.
The only place where strategy works is poker. With all other “gambling” you are mislead, believing that strategy can give you an edge. The only edge to watch is the house edge.
I’m not sure you really understand what ‘basic strategy’ is.
The name was originally coined regarding Blackjack, tho it applies to other games such as Video Poker, too.
Basic strategy tells you the correct way to play in order to lose the least. There’s no thought or decision-making involved, it’s a simple chart which, if you follow, you will do the best it is possible to do in that game.
I guess therefore ‘strategy’ is a misleading word. I suppose it could be called a recipe, or a decision chart. Follow it exactly and you will lose the least possible – over time the money you lose will equal the house advantage for the game.
Deviate from it, i.e. play by ‘instinct’, and you will lose more money in the long run.
There’s no real comparison with poker, which is a game of skill. Casino games feature no skill – memorise the chart and you will play the best it is possible to play, and lose the least it is possible to lose.
No-one ever said basic strategy allows you to beat the casino – quite the opposite. It just ensures you lose as little as possible, and are playing to the published HA. Play basic strategy BJ and you will lose roughly 0.5% in the long run (depends on the rules used) – play by instinct and you’ll lose 2+%.
