What do you use for learning/remembering Ranges

What do you use for remember Ranges ?

Hi Cardmates 

I'd would like to hear your thoughts on what are good options for remembering Ranges.

One of the quickest way to sharpen your poker decision making is to know what the optimum decision for any given spot is, and for that we have ranges.

Doesn't mean we always follow that, but knowing the default before you make your play is very helpful.

This works best preflop, where is there a limited number of ranges to memorise, but even here you can have 9 positions at varying stack depths, and then a set for FR vs 6max and so on.

Personally I've never made a conscious effort to memorise these (beyond a little work I did with push/fold tables some years back) and relied on post game analysis to teach me when I was off and use that to gradually refine my instincts.

What about you, Do you study charts and try and memorise them take tests until your scores improve.

Look forward to hearing your preferences.
