Hi,
He doesn't really look like the type to check/raise worse hands on the flop so i doubt our pair of tens is good on the river too often. That being said it's really hard to make a "bad call" getting nearly 5:1, so since you don't have many hands on him and some donks will show you 9x 7x or JT for a split, you can call when in doubt and figure out what he's doing.
Hope it helps.
