Thanks for your reply. So there isn’t a big difference when Ivanhoe uses more than one core against to such a good engine as robbo! That means that the code of Ivanhoe is clearly better. A big bravo to everybody who develops this engine!
Results can fluctuate / varey depending on your system / pc my own test had Robbo do a bit better still loseing to ivan but by a smaller margin , iggorit fares slightly better on my system :idk:
