"... Komodo mastermind GM Larry Kaufman introduces Komodo 13
May 6, 2019
We have just released Komodo 13.01. The normal version is about ten elo stronger than Komodo 12.3, while the MCTS version is about thirty elo stronger on one thread, and over forty elo stronger on four or more threads at blitz time controls.
While the MCTS version is not yet as strong as normal Komodo (unless you are using MultiPV), we believe it is among the top 5 CPU engines, and we claim that it is the number 1 CPU engine when MultiPV is set to 6 or more.
Komodo 13 MCTS is much better than previous versions in its ability to utilize hardware with many cores. Elo gains in MCTS mode from version 12.1.1 are in the 250 to 350 range. ..."

Me, here:
- Multi-PV affects Stockfish's time management: the higher the PV number the faster Stockfish over-aggressively uses up its base time in long thinks. See http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?pid=582892#pid582892
- Here Stockfish's setting 'Slow Mover' is 28 (not the default 84).
-- This makes Stockfish's time useage quite close to KomodoMCTS's.

In this wild book opening both played the Evan's-like 9.b4.
As black KomodoMCTS accepted, 9...Nxb4, and lost the shortest and extraordinarily complex game.
Stockfish declined, 9...Bb6, and won a short game with a spectacular attack on white's king. [Event "SfPV6-KoMpv6_1"]
