Up Topic The Rybka Lounge / Computer Chess / Alekhine Defence, Quixotic 1.e4 Nf6 2.e5 Ne4?!
- - By MrKris (***) Date 2019-07-16 22:46
AMD PhII X6 6-cpu , 512M Sy.6
G/16'+4" , all c=0

Overall, RR x 5 openings
13.5/20 - 68% - Stockfish 190713 (white 90%, black 45%!)
9.0/20 - 45% - Houdini 6.03 (white 70%, black 20%)
7.5/20 - 38% - Komodo 13.02 (white 65%, black 10%)

1) White 83%: 1.e4 Nf6 2.e5 Ne4?! 3.d3 Nc5 4.d4 a 'main' responce to 2...Ne4?!, driving the knight to a6 instead b6 from 2...Nd5.
2) White 83%: 1.e4 Nf6 2.e5 Ne4?! 3.d4, the other 'main' variation, leaving the knight in danger.
3) White 75%: 1.e4 Nf6 2.e5 Nd5 the normal move for comparison.

1) White 67%: 1.e4 Nf6 2.e5 Ne4?! 3.c3!? d5 4.b4 a5 5.d3 Nxc3 6.Nxc3 axb4 (diagram).
An idea from KomodoMCTS, 3.c3!?. Instead of trying to save the knight (3...Nc5) top engines like 3...d5.
Then if 4.b4 Stockfish likes 4...a5, sacrificing the knignt for 2 pawns, instead of trying to save the knight (4...d4, 4...Ng5 etc.).
2) White 67%: 1.e4 Nf6 2.e5 Ne4?! 3.c3!? d5 4.b4 a5 5.b5!?.
Stockfish won both its white games with its idea of 5.b5 declining the knight altogether, allowing c5 as an excape square.
