pocket pair play in 6max cash games

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?

there is two people making the mistake in this situation in a ring game .. the person pushing all in with 66 or the person calling all in with AK.

i dont even call it a coin flip when its a ring game, the pair is ahead 55 to 45, that small of an edge isnt worth it unless youve seen his two overcards everytime before you push. after a few 10 thousand situations exactly like that will this ever show a profit.

so you should only push with 66 if you're pretty sure they will fold?

I never push with small PPs in cash games; short-handed or otherwise.

Why? Two basic reasons.

(i) Even though you have a small edge over two un-paired over-cards, why risk your whole stack on such a small edge? I'd rather see a flop and try to hit a sneaky set and take my opponents' whole stack (in other words, implied odds will increase the EV of these cards played this way relative to a simple push as a 55:45 favourite).

(ii) You have a small edge pushing with small PPs only if you are correct that your opponent(s) are in fact sitting on un-paired over-cards. What if you are wrong? The times that you are wrong and you are in fact up against a higher pocket pair will definitely erode away at that 55:45 advantage. Making this play go from being slightly EV+ (assuming you can be correct 100% of the time), to EV -ve.
