I took my friends to a local Casino a few weeks ago (needless to say they enjoyed themselves) I won £30 on the Blackjack table (bearing in mind I am a student and only took £50 out with me) Whilst I accept that playing £2 minimim with a bankroll (albeit a laughable bankroll ) of £50 was poor mathematically I was pretty happy (and got let off pretty lightly). Anyway having spent the last few weeks memorising basic strategy, counting through decks, reading blackjack books, getting my girlfriend to deal out cards, doing mock casino tables complete with chips in the kitchen etc I am more lost than I was to begin with for a couple of reasons. Firstly I started with KO as it was the easiest to learn and have also learnt HI-LO since. (Blackwood mentions in Play Blackjack Like The Pro's that KO is more efficient than HI-LO aswell?) with the intention of learning HI-OPT I / II soon however having made no further trips to the casino's is it worth doing the extra work at the moment? Secondly I would like to know how playing against multiple decks affects play. If i have grasped this concept the only difference is that a True count and Running count are needed when playing against more than one deck? How many decks is too many? And finally how can I tell if a game is worth playing. I know that deck penetration is important, as are the offers for re-splitting, doubling after splits and so on but are there any particular rules that are an instant deterrent or should simply be avoided at my level of play?
