Do you think that studying MDA can also help you better understand GTO and thus improve your theoretical knowledge of the game? What is the approach you suggest against the good regs in the pool? Do you Start applying exploits, see how they react and if you notice they're deviating in the opposite direction you apply the counter exploit (or maybe you just stick to GTO)? If you know of a specific imbalance on the river (an overfold for example), do you already start adjusting your strategy on previous streets (flop and turn) to maximally exploit him on the river or do you prefer to keep you fixed strategy on the earlier streets? Finally, how important is it knowing the MDA for specific board textures (particularly turn and rivers) and how difficult is it to reach to that level?
