One of the biggest obstacles keeping most blackjack players from improving their game is that they aren't realistic about their current skill level. It is human nature to overrate ourselves and few of us are very objective in analyzing our flaws. A large number of tourists think they play basic strategy accurately. They may even have read a book or bought a laminated card intended to teach them the correct method. Yet in the fast-paced environment of the casino, what little they learned often melts away in the heat of battle. They never quite embedded proper strategy into their brain so it became second nature. Instead, they use some combination of correct plays and hunches.
