[Guenther Simon]

Hello Jan,

I believe giving diagrams or mentioning the positions you mean,
helps a bit My guess is you meant those positions below?

Spike: Nxg5?
[diag]r2q1rk1/1b1nppb1/1p5p/p2p2pn/1PpP3B/P1P1PN2/2BN1PPP/1RQ2RK1 w - - 0 15[/diag]
r2q1rk1/1b1nppb1/1p5p/p2p2pn/1PpP3B/P1P1PN2/2BN1PPP/1RQ2RK1 w - - 0 15

Spike: ...Bxh3?
[diag]r1q2rk1/p2bppbp/pn4p1/3pP3/3N4/2P3BP/PP1N1PP1/R1Q2RK1 b - - 0 16[/diag]
r1q2rk1/p2bppbp/pn4p1/3pP3/3N4/2P3BP/PP1N1PP1/R1Q2RK1 b - - 0 16

I could reproduce Nxg5? from example 1, but in example 2, Spike changes
here very quickly to Bh6 even on my slow second machine.(WB)
I read somewhere that Spike had a problem with CB Guis which is fixed
in newest version 0.9a?
BTW doesn't it save the depth too, when using that 'ugly' format?

Best regards,
Guenther

Yes, those are the positions, I'm sorry that I didn't point that out. About Bxh3:yes when analyzing it plays Bh6.....but try playing Bxh3....score ~0.00.

[Volker Böhm]

This is a known issue in Spike and not a bug. Spike is built to be an aggressive playing engine that preferes to attack kings. In some positions Spike does overrates the king attack.
