IM van Mil commented on the game as follows: "I was deeply impressed how beautifully I was outplayed by DARKTHOUGHT. I was lost but the computer missed one thing. I had a potential breakthrough which was too far away for the computer to comprehend. Because of that it opted for the wrong exchange of pieces." 38. Qc5 instead of 38. Be2? keeps White's obvious advantage.
