The real question is, what engine can see the sacrifice in less than 3 minutes using a regular PC, not a super pc with more than 2 processors etc......

1. e4 {What a day it was! What more you could ask for? Well, today's round
featured one of those rare days where we have thrillers everywhere on the
chess board. Let me not scare you, and sum up some minor things. Well first,
we had a solid draw between Kramnik and Adams. Boo. Then we had Giri chase
Vishy's king but left with a draw. (He is an artist after all) Then we had
Aronian over pressing and losing against Maxime. Then we had Wesley demolish
Topalov's king. (As usual) And then well... this game. Let's keep it as
suspense. So that was the things which happened today. Mind blowing, right?
Even more so, when you see this game, the best of all, a Caruana-Nakamura duel.

Re: What engine see the Queen Sacrifice of Caruana game vs N
According to ChessBase (http://en.chessbase.com/post/a-master-c ... an-machine) the move that is really hard for engines to see is 21. Nf5:
[D] r1bqk2r/5p2/p2p1b1p/3Np3/1P1NP1BP/8/1PP2B2/2KR3R w kq -
(Houdini Tactical is said to be fast on this though.). Without this move the Queen sac looks maybe equal but after 21. Nf5, White is winning.

Re: What engine see the Queen Sacrifice of Caruana game vs N
I disagree with the comment that this position should be evaluated manually because stockfish can see that 21.Nf5 gives advantage for white and not equality(maybe not in the first few seconds but it is known that engines see more with more time and people who analyze seriously a position should give the engine more than few seconds).Paloma wrote:Game Kommentary and Variations on

Stockfish can see a big advantage for white after 21.Nf5

Re: What engine see the Queen Sacrifice of Caruana game vs N
then youre just arguing semantics; he's saying you'd either have to force Nf5 manually or wait 5-10 minutes for SF to see it.
