You would win every game but it would be fun to watch.   

Would you set up Mogo to run on KGS so we could watch all the games and
of course never take back a move?   

Are you actually willing to wait for 20 minutes per move and are you
saying you will limit your own thinking time?   (Humans improve more
with extra thinking time than computers do, every computer chess
programmer knows this - it's all about the error rate stuff I talked
about.)

Again, even if you do all those things I think you would win all the
games - but it would still be fun to see if you feel any resistance
whatsoever.
