Game 2:

Komodo sacrifice a pawn for obtaining pair of bishops. Komodo's king activity is proving ample compensation for the pawn. However Komodo is not able to break through.

Question for Mark: Is King walk heuristics adjusted in Komodo recently? My impression is that Komodo is more keen in letting the king taking a stroll, over the board. Maybe Komodo is inspired by Stenitz.

We worked on King Safety lately and some is in K 11.2.2, but thinking much involving king "trolling". In a development version we did another change for king eval which is more likely to encourage the king to go toward the opponent's side of the board, but it is a pretty small change. Komodo in the past has been known to take king strolls, like this one in a past TCEC: https://www.youtube.com/watch?v=HoUDv08wXRI

When the opponents Queen has 'self stalemated' itself, I guess the King can wonder all he wants!
