I was playing stockfish at level four a couple of days ago when it hung a mate in two.  I know that level four isn't that high, but this still seems like an implausible error.  True, Stockfish will make odd moves when it is hopelessly lost, but in this case the evaluation of the position showed it to be  only a pawn down.

I checked for horizon effect problems, but there were none.

Yesterday in a slightly advantageous ending against stockfish at level five, I attacked two pieces.  It could move one to defend the other, but instead it gave up a piece for nothing.   I analyzed the position, both by myself and with a stronger version of Stockfish, but there was no reason to give up the piece.  I was about 70 centipawns up according to the computer.

These games were all at g5+4, stockfish usually had four minutes or more when it erred.

Has anyone else noted strange underperformaces in Stockfish lately?  This isn't happening, sadly, because I am getting better.

Sometimes when we become a grandmaster, like you or me, the opponent looks feeble.  The opponent must err in some way.  That it looks funny to you is
merely that you are used to less ignoble ways of dealing with loss.

Still feeling under the weather, so I'm playing stockfish at  level five.  I wasn't really trying in this game - as you can see from my Knight blunder..  Stockfish just folded.
