From Jonny-Komodo:

6rk/1b4rp/1pp2bpn/p2pNq2/3P1P1P/1P2PB2/PB4RQ/5R1K w - - 5 38


Both Jonny (and Komodo) missed 38. e4!, which Stockfish-dev saw instantly. Below are the three best replies, according to SF-dev.

Yes, it looks like it is definitely a win for white if 38. e4 would have been played.

I played the game from move 38 on my own system.  I substituted SF dev 160716 in for white, and kept Komodo 10 as black. 

Hash: 8 GB
Ponder: off
TB:  6-men Syzygy on SSD
OS: Windows 10 Home 32 GB system RAM
GUI:  Arena 3.5.1

Time Control: 120 min + 1 min because my system NPS is approximately 1/4 that of TCEC for the same position. 

I used Komodo's NPS for move 37 on the TCEC hardware  and compared it to Komodo's speed on my system, for the same thinking time.

The actual time remaining in TCEC in the game at that point was about 1 hour for each engine.  I doubled the remaining time and increased the incremental time from 15 seconds to 60 seconds.  Hence, using TC of 120 min + 1 min.

I stopped the game after move 65 on my system, because by then, both engines had found a TB win for white for several moves.  If we go by TCEC win rules, the game would have been declared a win around move 64 or 65 as well since both engines had been +6.50 or more for about 4 moves (8 plies).

I am running it again from move 38, with SF dev 160716 as white and SF dev 080716 as black.  I will post the results of that later, but it appears to be trending to a win again.  The evals are increasing steadily in favor of white, after each move.

Here is the same position, and settings as above, but with SF dev 160716 as white and SF dev 080716 as black.

Virtually the same result, with a TCEC win condition being achieved for white by move 66, as +6.50 eval for white from both engines for 4 moves (8 plies).  Both engines also reached TB win or near TB win at that time.
