Fast table-driven move generation

[hgm]

Why not just generate moves progressively until you get an alpha-beta cutoff? Saves on generating wasteful moves that only bloat the search tree.

Sorting: Most engines sort the moves in order of their relevance (MVV/LVA or history). Moves cannot be sorted if they are generated one by one.

But you could of course generate the captures in MVV/LVA order. History would be more difficult.
