Lol a whole lot of the posters so far must be A ranked players or realllly full of themselves.
It all depends on how well they are playing. If they make more mistakes than usual, then I can see myself getting to 10 in winner breaks and maybe 20-25 in alternate breaks.
But then you also have to factor in the bet size. It wouldn't be cheap, and no one is dumb enough to back me against them, so I'd be putting up my own money. In which case, 5 games.
i'd probably have to give both of them at least the 7 on my home table for them to even get past 50 games
