I can assure you that if we play together 30 games and finish them today, there is no chance you or i will beat the other 100% of the times!
But as i see here this is not the case since they both play a huuuuuuge number of games at the same time so this is somewhat possible although i see maaaany resigns.....?!?!?
Notice how many games they have playing against each other! !!!!!!ENORMOUS!!!!! value......
And 40 days per move.
