I thought Zenith Go is similar strength to CrazyStone but apparently I was wrong. I purchased Champ Go HD which running on iPad and purchased in-app for Engine Server Game (8-core-Server) which according to the notes is the 6 dan KGS and the machine that won the eight UEC Cup GO Tournament.

I also purchased Zenith Go 4 so out of curiosity I ran Zenith Go 4 on my office PC intel-i5-4-core, 8 GB RAM, set for 5 second thinking and play against CrazyStone (engine server Lvl 10). At the beginning I feel that CrazyStone was leading at least until the first 50 moves but later Zenith did some amazing attack, I feel that CrazyStone does not understand sente very well.

After move 220, finally CrazyStone admit the defeat.

Here’s the record for those are curious.
