Hello. This is my first post here so don't beat me hard :)
Some casinos in my area offers BJ with joker (joker is 313 card and count as any card for player and as no card for dealer). Question is - where i can find literature or internet resources about tracking it and how joker arise my edge over game?
And 2nd question - by the rules 6D, S17, DOA, DAS, RSA, RS(4), NHC (no hole card), ES (early surrender at any dealer's card) (but penetration is awful - 50-60%) what system is preferable. Is any counting system effective or because pen. BS is enough?
