Basic Blackjack Strategy

Introduction

Blackjack has always been the favourite for seasoned casinos gamblers as the house advantage on Blackjack is very low (usually between 0.3-0.7%). However these odds assume you are playing according to optimal basic strategy. Needless to say, you can't expect to win very often if you hit on 20.

This means you need to play smart and to know when to hit, stand, split etc based on knowing only your hand and the dealer's face up card.

Golden rules:

• Never take insurance (it increases the house advantage by 5.8-7.5%).
• Card counting will not work as online casinos typically re-shuffle the deck after each hand.
