just wondering if i have this correct:

in the later rounds of tournies, it is often the correct play to push all-in with a mid pocket pair like 66 against a single raiser who you think has high unpaired cards. when i've been playing tournies i see this race situation a lot.

however in cash games, the value of pushing all in over a single raiser on a pocket pair goes down unless your read is that they will likely fold or have a junk hand (like raising to steal the blinds). is a 50/50 flip for your stack a good play in cash games? just wondering because i see lots of people using this play online in cash games, and i'm wondering whether its because they watch too much WPT or something?
