  We present a new quadratic Chabauty method to compute the integral points on
certain even degree hyperelliptic curves. Our approach relies on a nontrivial
degree zero divisor supported at the two points at infinity to restrict the
$p$-adic height to a linear function; we can then express this restriction in
terms of holomorphic Coleman integrals under the standard quadratic Chabauty
assumption. Then we use this linear relation to extract the integral points on
the curve. We also generalize our method to integral points over number fields.
Our method is significantly simpler and faster than all other existing versions
of the quadratic Chabauty method. We give examples over $\Q$ and
$\Q(\sqrt{7})$.
