SF doesn't see mate in 8

Post by tpoppins » Thu Jun 28, 2018 6:19 pm

In a recent 40/40 game between Deep Fritz 14 and Wasp 3.0 after the opening moves

1. d4 f5 2. Bg5 h6 3. Bh4 Nf6 4. Bxf6 exf6 5. e3 g6 6. Nh3 Kf7 7. Nf4

the following position arose

rnbq1b1r/pppp1k2/5ppp/5p2/3P1N2/4P3/PPP2PPP/RN1QKB1R b KQ - 0 7

here Black fell into an opening trap I hadn't seen before:
7...Bd6? 8.Bc4+ Kg7 9. Nxg6! Kxg6??

Image
rnbq3r/pppp4/3b1pkp/5p2/2BP4/4P3/PPP2PPP/RN1QK2R w KQ - 0 10

and after 10. Qh5+!! the game was over in three more moves.

Curiously, SF 06252018 (the Brainfish compile) endorses 7...Bd6, a move after which Black's game is beyond repair, even at d=42:

Code: Select all

rnbq1b1r/pppp1k2/5ppp/5p2/3P1N2/4P3/PPP2PPP/RN1QKB1R b KQ - 0 7

Re: SF doesn't see mate in 8

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
