Yes, I want to kill the opponents as much as possible...I am a nice guy:-)

The third setting I made (actually the first one), before Colombus' egg was
Shredder 9 SN3, which is somehow the father of Columbus' egg...

Shredder 9 SN3

by Sandro Necchi

King safety = 112
Center control = 103

rest default

This setting was tested a lot  by me and the outcome was the following:

1) somehow weaker than Shredder 9 at blitz; about 20 points
2) somehow stronger at long time controls; about 15 points
