Well curiosity got the better of me, see below.
Hello Nick,
Thank you for your email to PokerStars.
Unfortunately we do not have a specific filter yet that isolates out the deep stack tournaments nor do we have general deep stack tournaments at 30 minute levels with 10,000 starting chips.
However, I will pass your request to our Poker Room Management team for consideration. Please bear in mind that we get thousands of requests, suggestions, and ideas each month, and we cannot reply individually on the merits of each one. While we cannot possibly accommodate all requests, we do read every single one and consider each carefully.
In the meantime, may I suggest you just type in the word 'Deep' in the Tournament filter box. This will help you screen out the tournaments and show only Deep Stack events.
Our lowest buy-in right now is $11 and these games can be found under the Tourney -> Regular -> Low Tab in the main lobby.
If there is anything else we can do for you, please let us know and we will be glad to help you. Best of luck to you in our games!
Regards,
Lawrence
