Both fixed.

I have checked, and found that it was Fuego128t that lost that game on 
time, not EricaBot.  I have corrected that.  EricaBot was indeed on six 
wins from 7 games.

It is dead as a result of competent play - Black should remove all ko 
threats (which is not always possible, but is possible in this game) 
before starting the ko.

There are many different screen resolutions, and I cannot plan for them 
all, so I selfishly plan for my own screen.

Are you using Windows?  If you are, you can type control-minus to make 
your browser render everything smaller.

Best wishes,
