Abstract
We define parameterized complexity classes that allow us to investigate the complexity of k-move games. We establish a number of concrete hardness and completeness results for games such as the k-move versions of Geography and Chess. We relate these classes to bounded space computations.

Flum and Grohe argue that this makes the A-hierarchy a natural analogue of the polynomial time hierarchy. The other possible analogue according to our results would be the AW[t] hierarchy. Space considerations preclude us for a discussion, and we refer the reader to [312].
