a good test position for developing engines

[Togga]

1.e4 c5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bb5 e5 5.Bxc6 dxc6 6.Nxe5

when the engine finds and play quickly 6. ...Nxe4

then the engine is very good.

I don't see how that wold help you developing an engine in any way...

1.e4 c5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bb5 e5 5.Bxc6 dxc6 6.Nxe5

when the engine finds and play quickly 6. ...Nxe4

then the engine is very good.

Well, of course all engines can find that as it is very simple, but it depends on the evaluation whether the engines think taking the pawn is better. For example, my engine first wants to take the pawn but then decides that 6...Bd6 is better:

[Togga]

look at the analysis of Alaric 707 and rybka 2.3.2a.
some engines finds Nxe4 very late.

i want that engines play this move at timecontrol 2 min + 2 sec.

[Togga]

i read somewhere that engine developers use test positions for developing, testing engines.
this is a good test position.

[Togga]

Nxe4 is a better move than Bd6.
look at the game between Anand-Kramnik.

[F. Bluemers]

i read somewhere that engine developers use test positions for developing, testing engines.
this is a good test position.

You mean that not_to_good engines won't find and play Nxe4 quickly?
why not?

imo one position tells just about zero about engine strength.

[Togga]

i thought so,the engine is then more flexible. cant explain it yet.
it scores then more points at timecontrol 2+2 matches:)
