As I mention in another thread, I'm new to playing blackjack at the casino. As a new player, I'm thinking hard about just correctly playing basic blackjack strategy. I compare it to learning to drive a car. In the beginning, trying remember all the rules and how to keep the vehicle moving forward was tiring for me as a student driver. Later, those things became second nature. Only after that was I able to relax a bit and learn to drive well. I expect to be able to handle longer sessions at the blackjack table as time goes on and I gain experience. Currently, I can maintain a quality concentration level for about 1-1 1/2 hours. After that, I start getting tired and lackadaisical. How long are your blackjack sessions before you need to take a break and recharge?
