Search fixes and the first evaluation improvements, including tapered PSTs and a bishop pair bonus.

Changes

  • Allow futility to filter all moves and return oAlpha in that case.
  • Fix infinite loops when showing PV.
  • Fix mate killer addition condition.
  • Generalise bishop counting using board.pCounts.
  • Don't allow a killer to be the (current) hash.
  • Don't research ALL node LMR fails unless R is set!
  • Arrange things so that QS doesn't use or affect node killers/hashes etc. In tests it's less nodes.
  • Increase asp window and add time on ID research.
  • Add crude bishop pair bonus imp. NB: updating a piece count array using a[i]++ and a[i]-- was too slow!!
  • Use tapered PSTs.

Usage

Runs in a web browser (or a web worker). There is no offline/UCI-GUI support yet; Node.js support arrived in 1.13.
