Board size would hamper old brute force algorithms. Modern Go AI also has "intuitive" components just like we do (large neural networks trained to immediately provide a heat map of what should be the next best move). That NN is not limited by board size. BTW, even when playing by "intuition" alone (no tree search), AlphaGo is still incredibly strong. It would still beat most amateur players that way.
