What emerges from this design is something resembling a tiny virtual machine built on top of TeX’s macro expansion engine. The \count registers serve as RAM (with dedicated address ranges for the board (200-263), scratch computation (188-194), and the search call stack (10000+)). The \csname lookup tables act as a read-only ROM for precomputed data (file/rank mappings, piece-square tables, material values). Token lists (\movelist, \legalmovelist) serve as dynamically allocated buffers. Macros like \makemove/\unmakemove and \pushstate/\popstate are the instruction set. TeX’s \ifnum and \loop primitives provide the control flow. The whole thing is a register machine with no stack frames, no heap, and no garbage collector (just flat integer registers and name-based indirection). pdflatex is, in effect, the CPU executing this VM.
