The exercise here is to write out what your flop range is and how you play each hand in your range.

For example, if your range on the flop for some reason was just {22+}, you might bet {TT+, 66, 55} and check {99-77, 44-22}. That's all we're looking for is for you to list how you play your entire range here after open-raising from the CO and acting first on this flop.

I am raising pre-flop here with 22+, A2s+, A8o+, K9s+, K10o+, J8s+, Q9o+, 108o+, 97s+, 87o+, 54s+

I am betting 22-66, JJ-AA, A2s+, A8o+, K9s+, K10o+, J8s+, Q9o+, 108o+, 97s+, 87o+, 54s+
I am checking 77-1010
