An unbalanced position has arisen straight out of the opening, in which, with an open centre, Black has a pawn and the bishop pair for the exchange. Is it enough compensation?

<...>

Anyone willing to volunterely help me research this imbalance further, - arrange with decent hardware K10.1 with white pieces against SF Dev as black or vice versa. TC 90+30 atleast.

Apparently, White wins but it may take a TC a lot longer than 90m+30s to prove.

Stockfish: 21h 7m 24s
Komodo: 21h 27m 17s
Total analysis time: 42h 34m 41s, the actual time was less since the analysis was done on two separate boxes and often ran concurrently when the opponent's next move could be predicted with certainty from the previous PVs.

Although the times consumed by each engine are quite close this closeness is deceptive. During one of SF's turns I forgot to stop the analysis and it ran overnight for 9+ hours. At least 8 of those were pure overkill. Komodo's rising score constantly lagged behind that of Stockfish despite spending 2X-3X longer on many moves and having four cores more at its disposal.
