Even if you are not a slots player I am willing to bet you have heard of hot and cold streaks. It is when a slot machine is either paying out often or is paying next to nothing, respectively. I have crossed paths with a number of beginner blackjack players who smirk at slot players, believing that they are playing a game that is above hot and cold.
Blackjack is not above the hot and cold phenomenon. It relates to the dealer. When a dealer is hot is winning more than he is losing; and a cold dealer is he is not winning as many hands. Obvious which dealer you should want to be playing with right?
Like with slot machines, there really is nothing a blackjack player can do if they find themselves with a hot or cold dealer. Not that you would want to give up a cold dealer and all those opportunities to win.
What do you do when you find yourself with a hot dealer though?
Finish the round you are playing, and then take your chips and find a new table. There is nothing that says you have to play at only one blackjack table or at the same blackjack table. You can hop around. So if you find yourself at a blackjack table with a hot dealer, leave!
It may not always be immediately apparent that you have a hot or cold dealer. The trick is in observation. Watch the rounds, see how the dealer does. If he is winning more it would be a good idea to find another table; and if he is losing more often then pull up a chair and play some blackjack.
