What and where do you suggest I research? I am working on index plays at the moment, in particular insurance. Is the right TC for insurance +4? I was lying in bed thinking about this last night. 9-4 is the ratio of non ten's to tens, so you would think a TC of +4 would be perfect for insurance (since there are 4 suits of every card, if you knock off four non tens for every deck you have the right insurance decision, but my count has aces as +1, so this would seem to be inaccurate). Anyway I am all for preparation! I lost 200 units today (at a number of points I was betting 75 units a hand (3 * table max), which is obv. a pretty bad idea). I was down much worse at one point - probably 300-500 units, luckily I had a pretty monster hand with 5 * table max on the table (3 hands + splitting and resplitting seven's against a 3 (or was it 3's against a seven?)) and took that down. As bad as all that may sound I am up 1000+ units in the past couple weeks, and looking to change to a much lower variance strategy and cement the win.
