And just to expand ^^ a little.
Look for specific flop textures to try and get thin value from bad villains. Monotone flops are excellent examples, coz bad players will just c/c 2 streets with a big suited card and so you can get 2 streets of value with a bad pair then just c/f if the 4th suit hits on the river. Flops like 67J. You can get alot of value with a hand like A6 or 78 on this flop and alot of turns because guys will stick around unecessarily with SDs and GSs.
Here is an example which might make it a little clearer - far from a typical thin value but if you follow what i say about it i think you should understand better.

At first glance this probably looks terrible on my part. Against most players you'd think i'm sort of mixed up and half bluffing half value shoving this flop. Basic point being that in a vaccum this looks anything but standard.
However, in this case, villain is pretty wild, although he does have a clue. Stats are like 62/56/9.75. 3B% of 58%, cbet% of 100% and double barrel% of 55%.
So on the flop we know nothing about villain's range except that i crush it. On the turn, villain's range has tightened somewhat, but it is still quite wide and is far more than a J. 58% 3B means a huge range of hands, tons of which are stuff like 9To or 86o, etc. Now the reason i shove is this - i can't really call a 3rd barrel from villain (only cbet river 25%, and in any case i was moreorless convinced that a river bet would never be a bluff). So there is no way of getting the money in on the river and me being good, unless i make a retarded donk shove and expect to get called by like 3rd pair, which also isn't happening). That said, villain's range will have alot of 2nd/3rd pair hands or straight draws, which i don't think villain is folding on the turn at all (although he prob would on river) because sometimes i am going to just spaz out in frustration, sometimes i am going to shove a draw, and me having a J or overpair here (which is what i am representing) just isn't that likely. And so by shoving a hand very light like i do here, i am actually in a position where i can get called by ALOT worse due to metagame/board texture. So hopefully that helps.
