This will be the biggest grind in this game. If you have played this before, all the hands played before the update will count towards the achievements. You can check your progress in the Help & Options-Career Stats. The best way to grind this is to set up a 30 person tournament. This will allow you to play more hands and work on more achievements if needed. I was able to play about 150 hands just in a tournament that I finished 8th in. Also if you have the WP7 version of the game, all the games you play on it will count. Just to be safe, I would recommend not playing your 10,000th hand on your phone though just in case it glitches.
