Abstract

In this paper, we study (1:b)(1 : b) Avoider-Enforcer games played on the edge set of the complete graph on nn vertices. For every constant k3k\geq 3 we analyse the kk-star game, where Avoider tries to avoid claiming kk edges incident to the same vertex. We analyse both versions of Avoider-Enforcer games -- the strict and the monotone -- and for each provide explicit winning strategies for both players. We determine the order of magnitude of the threshold biases fFmonf^{mon}_\mathcal{F}, fFf^-_\mathcal{F} and fF+f^+_\mathcal{F}, where F\mathcal{F} is the hypergraph of the game.
