Thanks Colin! Stockfish still needs 60 million nodes so not super easy for it. It's nice to see the score shoot up suddenly. Good test for all engines for instance because the score is so clear.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Re: Interesting position, best move b4

Post by Eelco de Groot »

I think this first b4 position is only leading to a draw though, so not really a very convincing testposition.
For instance after [pgn] [Event "?"] [Site "?"] [Date "2018.07.21"] [Round "?"] [White "?"] [Black "?"] [Result "*"] [SetUp "1"] [FEN "1k1r2r1/pb5n/1qpp2pP/1pb1p3/4P3/1PNP1QN1/1PPB4/2K2R1R w - -"] 1. b4 Bxb4 2. Qf7 Qc7 3. Qxc7+ Kxc7 4. Nxb5+ cxb5 5. Bxb4 *[/pgn]

Hi Vincent, thanks for the analysis!

I still think the 1.88 value is closer to the truth than the 2.21 for 7. Kb2 Here everything stayed under two pawns. But this is with contempt still on (21) and version 10 of Kaissa but that should not matter so much. In the start position I got

65/79 1097:27+1.98 1.b4 Bxb4 2.Qf7 Qc7 3.Qxc7+ Kxc7
4.Nxb5+ cxb5 5.Bxb4 Rd7 6.b3 Re8
7.Kb2 Re6 8.Ne2 d5 9.exd5 Bxd5
10.Rh2 a6 11.Ng3 e4 12.dxe4 Bxe4
13.Re2 Bd5 14.Rxe6 (122.853.594.632) 1865

so a different move again after 6. b3 but more moves seem possible there.

Instead of 4. Nxb5+ another option is 4. Rf7+ The difference seems now minimal though.
