re: Poker & Quick Tourney Advice!
Once you double up a couple times from the beginning, its pretty easy to cash in the DD freeroll because you dont have to and shouldnt be relying on your cards. Once the blinds are large enough, you should just be shoving from position to keep a medium sized stack. The people you're shoving on should be other medium stacks just hoping to cash, and try to avoid people who are tilting or who you've observed to be calling stations. Otherwise unless your opponent hits one of the top ten hands they arent going to call you down. Picking up the blinds once each rotation keeps you alive with a good stack and affords you time to wait for a bigger hand, and its possible to pick up the blinds more than once per rotation.
Hands you should be shoving with against medium stacked tight players near the bubble (500 or less imo): Any pocket pair, any combination of face cards, AT+, and if you're getting short, suited connectors 67s+.
Dont get me wrong, even doing everything right dont expect to cash more than a couple times a week at most if you follow this meticulously. The first few double ups can be tough, as can choosing your spots to shove. Its akin to playing minesweeper, there are correct moves always, but its very easy to make a mistake.
