AFq: Aggression Frequency
Of all of a player's post-flop actions, AFq is the percent where they bet or raised. It's a coarse measurement of their overall aggression. Against aggressive players, you will have to call (or re-raise) more of their raises. Against passive players, you should treat their raises (and their calls!) with more respect. For specific situations, you may be able to use one of the related statistics for more precision.
