In the following game movei made a speculative sacrifice that is probably wrong.

Fruit likes 14...Nxd4 even after long time when rybka does not like it.
Fruit is more optimistic for black than rybka.
[D]r3k2r/ppp2ppp/2n2q2/b2p4/3P1B1P/P1PBPP2/2Q2P2/1R2K2R b Kkq - 0 14
It is not convincing to claim with no diagrams things like
"Indeed, I carried out several tests with "Rybka 1.0 Beta 32bit", "Fruit 2.1"
and "Toga II 1.0" in infinite mode.
I then noted a too great number of similarities in the sequence of discovered
blows("coups" in french).
The difference is that "Rybka" finds much more quickly the concrete solutions,
while "Fruit" and "Toga II" delay."
