Are you sure you don’t have a corrupt TB file?

I had the white pieces here. And I know that the Black player has at least 2 accounts on PlayChess and that the engine has been purchased. Whether he had corrupt TB? I don't know that. He plays a lot, he also played in today's tournament on PlayChess and even acted as tournament director. I'm assuming he's not a beginner.

By the way, the ad about CheckMate was correct. That is not the point. The question is, why did Dragon play that if it's checkmate? The alternative is to see the correct draw move, but Dragon didn't play the move --> 46... fxe6 -250.00/72 64 (Qxe6+) .

Hard to say. Dragon 3.3 at depth 35 found the right move. In an online match, who knows?
