AMAZING: vs Stockfish 230202 avx2 : 1000 (+ 0,=639,-361) .
There are a lot TB fixes now. Andrew have you measured TB gain for Ethereal?
It probably take at least 2 hours for Ethereal 14.00 to find the best move 1. Nf3, the only move that draw

Nf3 is getting mated in 14 moves, maybe fewer. Guess Ethereal must be much more powerful than whatever engine you are using. Good thing you have a copy.

That is because it is NOT following by Sacrificing the Rook, then Sacrificing the Knight on e5 by closing the position, [Moderation: no, it is because you messed up the FEN, which was not what you now show above in this 'doctered quote'] Sorry that I posted the wrong position which gave you the impression that Ethereal is better than Stockfish at solving this puzzle, see if Ethereal can find those move like Stockfish under 60 minutes per move

Needs a timeout.
Fat Titz by Stockfish, the engine with the bodaciously big net. Remember: size matters. If you want to learn more about this engine just google for "Fat Titz".

Heh, that position has been posted several times now.
He messed up the FEN or slipped when editing a board I guess. Black queen is supposed to be on d6.
Cheers!
You are correct here is the correct FEN, Dragon 3.2 without me changing the Contempt can NOT find 1.Nf3 after 4 hours neither.
Note: these 4 move guarantee a draw, but the engine has to sacrifice the Rook and Knight, NOT simply move the Rook to d4? and do NOT take the Black Queen if the engine offer it on d5 later on... and the Black King is near to snatch your White pawn, as it is the position is blocked by pawns and the extra Queen is useless. If any top engines analyze a little bit longer the 4 moves sequence after 1. Nf3 it will immediately find the draw, that is the reason why top engines can NOT simply select the 1st best move 1.f2-f3, since they are so materialistic

In reality most engines beside Stockfish do NOT evaluate the outcome of the 1st 2 moves, but I inputted the 1st 2 moves and it did NOT have any problem sacrificing the knight on e5 and blocking the position with pawns
