That would be a fun way to define computer opponent: introduce an arbitrary amount of allowed compute power. Say, allowing a purpose designed device, but limited to 1W of power consumption. Or some fixed energy budget (J) per move. Too strong? Take it down to 0.1W, 10mW or whatever. That would degrade brute forcing as a viable approach, and bring it back to smart algorithms, clever ways to reduce the search space, etc.
