Reading books may only help someone to know and add some strategies and tactics for playing and betting, this is only limited to adding knowledge and does not guarantee that they will win, after all knowledge will also be very important and can be very helpful when someone can use it well in add to the collaboration the experience they have gained.
A gambler must be able to seek more insight and knowledge to increase experience to become smarter gambler and not just rely on feelings or random bets, apart from luck I believe that anyone can increase their chance with what they can do.
I will immediately advise any gambler to watch these movies on gambling whether it will give them some insightful practical knowledge and understanding of how people gamble out there. The movies have their own storylines and were either talking about someone or playing a scenario that has happened in the past. Smartness plays a significant role in the activities of a gambler which is gathered based on experience. A gambler ordinarily gets more smarter in gambling when he plays frequently but with high level of mindfulness and study of events. If you do not invest that level of intuitiveness in your gambling, you will end up being a serial loser with experience but little or no results.
These movies are Casino, The Gambler, 21, Molly's game and Rounders. Casino was directed by Scorsese and told a story about the Las Vegas casino business in the 80s and 90s where gamblers battled for power and the level of corruption and chaos involved in gambling business. The Gambler movie played around gambling psychology and how a Los Angeles literature professor, Jim Bennett risked all his fortunes into gambling and ran into debts as a result. The movie starred a popular face in person of Mark Wahlberg who acted as the professor owing a loan shark over 50,000 dollars in debt and another gambling owner, Lee, a whooping sum of 200,000 dollars.
21 was a 2008 movie was directed by an Australian director and tells a story about MIT students who were recruited by a professor to loot casinos. Ben was a mathematics major who would later be initiated into the MIT Blackjack Team operated by the professor which comprises of other students and syndicates. Ben was invited after he performed excellently in a Medical College Test but yet find it difficult to pay his bills and the 300k dollars tuition. The professor saw that as a chance to initiate Ben into the card counting and convert signaling technique to beat casinos.
I won't talk about the rest two but this is just a bird's eye view for anyone who's interested in gaining some knowledge and experience on gambling.
