It depends on the conditions. If you’re playing in a casino that you know is sweaty then you might stick to a one or two cycle hit-and-run. In bigger casinos you can get away with it as long as you want. Wonging into the shoe game at the Western and betting several green chips will get you heat right away but you can do it almost all day long at the MGM (with much better rules too!).
Different casinos will require different tactics. It is very important to get a feel for each casino’s “choke point” and adjust your strategy to suit it. That may involve using different session lengths (time limit, bet cycles, perceived heat, etc.), different playing strategies (WiWo, White Rabbit Wonging, play all, different spreads, cover plays, etc.) or simply walking out without playing at all.
