How is the strength of the chain calculated?

Total proof-of-work.

So a very strong node could continuously reverse the last x blocks and only allow transactions which include a transaction fee over a certain amount, right?

A strong enough of a node could do *anything*, the entire point of the proof-of-work is that as the bitcoin network grows, this kind of takeover becomes; if not really impossible, increasingly and astronomicly improbable.
