For poker, you are playing against other players and it is possible to hold an edge if you are an expert player. For casino games, the rules are fixed and there is no way you can increase your probability of winning. No matter how good you are playing blackjack, you cannot win against the house dealer in the long run.
I'm ever play poker and try some method to make profit and it happen.
I with my friend work together to beat other player by bluff and play strategically. Once we got profit, we share 50 : 50
This is also a good strategy. But what if the other players will know that you two are working together?? They'll get angry for sure.
I'm not that good at playing poker but i still find it quite entertaining that requires skill. I'm always practicing and looking for some tactics.
