Re: Quick estimate please

One improvement of note for asmFish, made a few weeks ago, was for Syzygy, where DTZ was not always being probed once a DTZ position was reached.

Re: Difficult position for Stockfish

Latest AsmFish finds it for me in 7 minutes, using Syzygy 6....better late than never, I guess, and Qf5+ is also a Syzygy win found in 3 minutes.
