Is game review's 'best move' inaccurate?

See move 81, it says rook to b2 is 'best move', yet it drops the bishop. When I play versus computer this move it says it is 'innaccuracy' and kc6 is best.

Is the depth of game review (18) lower than when play versus computer. Or is this truly the 'best move'?

The "best" move depends on the depth of search.  A depth of 18 is fairly low.

The computer can't find anything good when you run the max analysis.

Thanks, makes sense.

Recommended Move

The analysis suggested take a pawn and lose a queen instead of forking and taking a rook with a lesser important piece, the knight. I don’t understand how that move could be recommended. Can anyone help me understand why this move would be recommended and the score could be so extremely different? (My score has been dramatically dropping over the past few months. I see these ‘recommended’ moves quite often and I’ve been ignoring them thinking it’s a glitch but my score has been taking such a free-fall, I need to understand the rational.)

Nxa1 and black plays Qxd7+.

I can't imagine how, but you simply confused the white queen on h5 with a pawn.

You wrote "take a pawn and lose a queen" but instead it is "trade queens, then take a rook".

The alternative is "take a rook" in your interpretation, but in reality it is "take a rook and lose a queen". Your queen is hanging right now, there is a white queen on h5 (see your first diagram).
