$11 6 max on stars, what to do against donk?

[Coz]

The villian in these two hands has been very loose, calling raises with a wide range of hands. Normally he calls flop bets with any pair no matter whether its TP/TK, two pair or a gutshot straight draw or a flush draw.

My reasoning behind checking was that I may be able to encourage a bet from a misguided bluff on the river, or a lesser pair, and also minimizing my losses by calling a smaller bet on river because his bets are generally small. Thoughts? Is my thinking process right?

This next hand is against same opponent, and a player just as loose as him in the BB, I thought about open shoving but thought that my stack was too big. Thoughts.
