In this note, we show how positional strategies for k-pebble games have a natural representation as certain presheaves. These representations correspond exactly to the sheaf-theoretic models of contextuality introduced by Abramsky-Brandenburger. We study the notion of cohomological k-consistency recently introduced by Adam Ó Conghaile from this perspective.
