Position 2: 3qr3/5pk1/p2p2p1/Pr1Pn2n/4P2p/5P1P/3Q2P1/R2N1RKN w - - 0 28 Classic Ara prefers the immediate 28.f4 at 1 million nodes, but 28.Ne3! is so much stronger. Classic Ara thinks that after 28.Ne3 Qf6 Black is slightly better, but it misses the counter-trick 29.f4! after which White takes over. |
