Where to start

Learn basic strategy first. The strategy chart shows every move, and the trainer drills it until you stop checking. Played well, a 3:2 shoe game costs you about 0.4%.

Then check the table

Rule	Effect on house edge
6:5 instead of 3:2 blackjack	+1.39%
Dealer hits soft 17	+0.22%
No doubling after a split	+0.14%
Late surrender	−0.08%

The house edge calculator puts your table's full rule set in one number and turns it into pounds per hour. Counting comes last: it's legal, slow, and only pays on top of perfect basic strategy.
