The term 'Overlay' is commonly associated with both poker and sports betting. In the realm of sports betting, the concept of Overlay revolves around odds that are higher than they should be, in a way that favors the player. These odds can be advantageous for punters and can lead to greater potential profits. However, in the poker world, the term carries a slightly different meaning. Here, we explore the Overlay concept from the perspective of Thai culture and gambling habits. In Thailand, gambling is deeply ingrained in the social fabric. Poker, a popular card game, is a significant part of Thai culture. The game is known as "Praew" ('ปัง' or 'face card') among Thai players. Poker hands are classified in the same way as in international conventions, including the 'Pair' (คู่), a hand that consists of two cards of the same rank. The 'Overlay' term, in the context of poker, is more specific. It refers to a situation where a player bets all of their chips. This is considered a bold move in poker, and it indicates a high level of confidence in the player's hand. In this instance, the term 'Overlay' implies that the player feels they have a strong hand and is willing to risk it all. This understanding of the term 'Overlay' can be seen as a reflection of Thai gambling culture. Thai gamblers, known for their 'hands-on' approach, often employ strategies that involve risking a significant amount of their stake in the hopes of obtaining a big win. This is evident in both sports betting and card games like poker. In conclusion, the concept of 'Overlay' carries different meanings in the contexts of sports betting and poker. However, both these meanings reflect the adventurous and bold spirit of Thai gambling culture. For Thai players, understanding the term 'Overlay' is part of their rich gambling heritage, and it adds to the thrill and excitement of the game.
