Blackjack has always offered a great value in the casino for anyone willing to learn basic strategy. Without card counting, a player that uses an accurate basic strategy at the table can play games at most casinos with substantially under half a percent house edge. Even the worst rules and conditions rarely exceed a house edge of 0.8%.
If you are a recreational player, you can consistently overcome that small edge with the value you receive from comps of free rooms and food. Why is it possible to get back more in comp value than your actual expected loss?
