So I've been playing 'perfect' blackjack a little on the side, and am on a little upswing. However I do have some questions
1- ROR (risk of ruin) I've been told that with 200 units you have a 40% chance of going broke, while at 1000 units it's only 5%. Can anyone give me the numbers WHY it's 40% at 200 units? and would it be ~50/above 50% when player has <100 units?<br /> 2. I understand if you play perfect BJ (basic strategy, dealers tells not included, no card counting, 6 decks) the house still has a 0.5 advantage. Why is this? how does one get to this number? Also, if the house always has a minor edge, how is BJ beatable? is it the whole variance+leave while you're up? minamo99 is online now Report Post
1 - From a card counting perspective, this may be true given the factors of how that person plays, the rules in the game, penetration, his ramp/spread, etc. From a recreational player's perspective, it comes down to how long you're going to play, rules of the game & HE, as well as strategy (basic strategy or poor strategy). But, if you don't have an edge -- you will go bust...eventually.
2 - Depends on the rules of the game. I'd say a common game in Las Vegas (where BJ pays 3:2) has about a 0.5% house edge (or 0.5% casino advantage). Determining the house edge is a bit complicated. Here's a video I found on one technique used to come up with the number:
Online casino blackjack is alot of fun with the basic strategy, that's a cool video. It shows a really complicated method but i will try to understand it.
