Dumb

A simple & stupid UCI chess engine

Dumb is based on the following algorithms:

• Bitboard/mailbox legal move generator based on hyperbola quintessence
• PVS/negascout search with aspiration window
• simple quiescence search (no see pruning)
• simple 4-bucket hash table (no ageing)
• simple evaluation function with knowledge limited to material, positional and tempo (no pawn structure, mobility, king safety, imbalance, trapped pieces, ...) tuned to probably suboptimal coefficients.
• simple (insertion) move sorting: hash move + mvvlva ordered capture/promotions + quiet moves (no killermove, no history)
• null move pruning (no lmr, lmp, razoring, frontier node pruning, ...)
• checking move extension
