I'm having a hard time understanding the whole concept of long-term/short-term. Does this mean that each session (no matter whether same day or week later) at a blackjack table is just one big session but just split up, basically each session is a continuation of the last and in the long run if you play long enough you will lose (considering u play straight basic strayegy w/ no card counting). It just confuses me because I feel like each session is independent of any other session with no memory of what happened in previous plays.

Say that everytime I go to the casino I only play 15 hands, isn't that short term? And everyone says that in the short term a player can win but it is in the long run in which a player with always lose(unless card counting). Therefore, aren't I always playing short term by playing only 15 hands a day.

And what exactly is long term. I mean the basic strategy was developed through simulating billions of hands, I will never play a billion hands, so doesnt the strategy change a little bit. Because a 15 hands a day player and a 350 hands a day player have different definitions of long term. Does this also mean that because one is playing 350 hands a day he will reach the "long term" (and his inevitable failure) sooner than the person playing 15 hands a day.

Im not sure if any of this is valid, I am a little confused about this topic and would appreciate it if somebody could clear it up for me. Thank You.
