Sure, it's possible to get heat as a red chipper (especially with a very large spread), but the EV you gain is not enough to worry about heat, especially when it's so rare at those levels. However, this becomes bad advice if you plan on moving up to higher levels later on down the road, as the time it will take you to get there will give plenty of casinos plenty of time to peg you as a skilled player. It's a bit of a conundrum, unfortunately.
But the Golden Nugget is worth a stop in, especially during weekdays.
