The World Sit ‘n’ Go Masters is being held this year in Prague. Many poker sites, including Ladbrokes, are offering the chance to qualify for free.
Let's be realistic about this, you haven't got much chance of qualifying, but if you don't mind playing a freeroll and then qualifier after qualifier only to fall at the final fence, well, as long as you can multitask, what have you got to lose?
Details of the tournament and the venue can be found on the official site. As you can see, this is now an established event. The two screengrabs - above and below - are from a recent stud tournament on Ladbrokes. If you look closely, you will see some writing around the inside of the table. It may not be clear, but this an advert for the Prague event. Alas, no stud there. It's No Limit Hold 'Em all the way. The Ladbrokes schedule can be found here.
