About VeryChess
VeryChess is a UCI-compatible chess engine developed as a personal software project at the intersection of chess and programming. The engine is designed to work with UCI-compatible chess GUIs such as Arena, Cute Chess, and BanksiaGUI.
Development is focused on building a clean, understandable architecture, improving engine strength through systematic testing, and documenting every step of the journey publicly.

What's new
This release covers two areas: search efficiency and time management.Five refinements sit on top of the table: History-aware reductions, Principal-variation reductions (LMR now applies inside PV nodes), Iteration-completion prediction (the engine now starts a new deepening iteration only when it predicts it can finish it within the budget), More realistic game-length assumption, "Move Overhead" is now functional.
