It’s possible to look for "warm" blackjack tables, which are perceived as favorable due to a higher concentration of high cards remaining in the deck. Skilled players may use card counting to track the deck and identify when the shoe is advantageous. In some cases, players observe dealer patterns or deck penetration to predict when the odds might shift in their favor. However, most modern casinos use automatic shufflers or shuffle frequently, making it harder to reliably find a warm table. Ultimately, any perceived "warmth" is often temporary and based on patterns or luck, rather than a consistent edge.
