I wouldn't be that confident on that, currently the qualifying entry list
ends in the 98th ranked, in this case, Jan Hajek.
In fact, it's the strongest Estoril Open ever, with the last player in MD ranked at 69.
There's no such thing as a qualifying entry list for 250 tournaments. That's the alternate list for the main draw. The qualifying has a personal sign-up period in Estoril until Friday night.
