Conversation
Add docs/engine-strength.md: a reasoned (unmeasured) playing-strength estimate derived from the current feature set and benchmarked search speed, with calibration against known engines, time-control sensitivity, per-roadmap Elo deltas, and the SPRT process for replacing the estimate with real data. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Depth/time/node tables for the current single-process search, perft throughput, and a fixed-depth baseline with an alpha-beta pruning estimate against full-tree perft counts. Measured on Apple M4 / Go 1.27. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Engine architecture, implemented search/eval techniques, and the backlog of unimplemented ideas, mirroring the pyChess design doc structure. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

docs/performance.md, a benchmark summary in the style of the pyChess doc, adapted to goChess's current single-process search.Contents
goruns today — single-process iterative deepening from the start position (depth 7 ≈ 3s, depth 8 ≈ 30s on this machine). No Lazy SMP.perftthroughput — move generation is delegated todragontoothmg; ~160–170M nps at the deeper counts, all matching published perft results.prunedestimate against full-treeperft(depth)counts. Alpha-beta + MVV-LVA reach "1 node in ~620" by depth 8; the doc is honest about the estimate's limits (depth 2 goes negative because unbounded quiescence with no TT expands more nodes than the full tree).Method
Measured on Apple M4, 10 cores, Go 1.27,
