I am new to counting. I have been looking at past postings and wondering what is the truth about ko-preferred. Someone posted that the ko book misrepresented it's power. Can it beat most games? I am looking mostly at 6d, 4d, 2d all with h17 das doa. Pen. are roughly 75-80, 75, 60. Bet spreads 1-12, 1-8, 1-5. I know that ko-full would be better but I like the rounded matrix, but is it too costly? I have been using the basic strategy training from this site and counting with ko-preferred with success. I have in only about 20 hours doing this. I know that I can get in a unrealistic amount of hands in, but I do have to play through large negitive counts. I am just wondering if I am playing a winning game? thanks in advance.
