Odd game analysis again - how is this a "blunder"?

saxon4413 vs. JBarryChess | Analysis - Chess.com

Look at move 11 for black. The analysis engine says moving the queen to b8 is a blunder and suggests moving the black queen to e6, but moving there will enable white to move its knight to C7 forking the black queen on e6 and black rook on a8.

i think you lost the queen anyway but keep more pieces and better position.

If you play 11. ... Qb8 then after 12. Qg4 your king is going to die in a few moves. That's why the engine wants to give up material.

No, continue the game, black won.

So what?

You asked why Qb8 is a blunder so I answered. It's a blunder because after 12. Qg4 your (black) king is getting mated.

Qb8 gets mated in six moves. Starting with Qg4.

The fact that White blundered and lost instead does not make Qb8 a good move.

The engine says Qb7 is mate in 6 for white. I don't know how JBarryChess isn't seeing that while looking at the Analysis. Maybe you're looking at Game Review instead? Or what?

Yes, I'm looking at the review, not the analysis. I'll look at that, thanks.

Thanks again everyone. The analysis is the real story. I was wondering why the review would say something was a "blunder" and I couldn't make sense of it at times. Getting old suks at times, lmao.

That's not your fault. "Game review" is absolutely useless for everything.
