I will leave it for the more experienced players to take it from here.
My opinion is that luck in the short term is significant while skill will overcome all in the long run. I do not base my play on luck, merely observe that cards do not always play out the way I want them to. I realize my opinion has no effect on the cards yet to be played. I play shoe games because I have to, and I base my betting strategy on my strong belief in counting and the ROR I can live with. Having learned 22 indices, I will only deviate from the recommended play with a risk-averse bias if the pivot is indefinite. I will continue to relate my bet size to the EV of each hand even if I am losing. I will call my losses, if I played correctly, attributable to standard deviation. The cards come out at random in a fairly shuffled pack. As I learn more about this game, I hope to become proficient enough to relegate the word 'luck' to the trash bin. In the interim, I use a session bankroll that I will not be devasted in losing, since my perception is that 'good cards' may not be part of the program on any given night. More often than not, the duration of my play is predetermined before I start. If I have an unusual opportunity, I will chase it around the block until I wear it out or the opportunity ends. If I am tired or have some other good reason to leave the game, I get up and go. The conditions in the Midwest are pretty predictable, so it is my opinion that the same game will still be there tomorrow.
Please feel free to educate me on these or any other points of interest. I am not being contentious in this offer. I have obviously not solved this game to my satisfaction, yet.
