I like the charts for the beginner. They helped me and as I think SSHE says somewhere, The charts will lessen the number of times one is faced with tough post flop decision. It won't eliminate them altogether, but it helps. For a beginner playing after the flop is harder to learn and takes more time. But, after playing, studying, posting, and grunching here on the boards, one should have a better idea of the reasoning behind the chart. At that point, their usefulness declines.
