NLP can have alot of usage in the game, either for working out the best ways to identify with your target or a group, maybe an Opener, or just helping to read someones words to suss their true feelings and emotions.
though its pretty useless without further reading into similer subjects i like to beleive(or at least what i use NLP for the most)
is to be able to offer myself and sitautions and questions with li miting the answers i will get back with the words that i used.
to an unsuspecting target(if done right)
metephor time!! 
-you work in a cafe, and you want to sell the larger of 2 coffees to a customer that doesnt really know what size they want
-if you offered a small and a large, large sounds intimidating and only really bought if you know you need a large amount, so they are more likely to get asmall becasue at least yo uknow you can handle it
+morever mentioning small fisrt will make them more likely to ask for a small becasue they heard it fisrt and are more familier with it or in a rush and may offer teh fisrt thing you asked for, ie saying "large or small" they are less likely NOT to say large but still will probably say it.
- if you were to infact offer a medium size(even if its the alrger of the two sizes by quite some amount) it doesnt sound threatening, infact it sounds like the normal size, and accomapied with its position, "medium or small"
now the "Small" option sounds like its the lesser and more to teh point, seams to be some ort of counter-offer for pe ople that dont want alot rather then another choice.
-ontop of this! if you didnt offer the small at all, but hinted that there were other choices, but only offered the alrger of the 2 sizes ie
"medium ok?" your not denying them the choice but they have to put in mroe conciouse effort to get the small size, and as they just want a coffee, its more then l iekly they will say"thats fine"
i work as awaiter and i have tested this down to teh ground.
unfortuantly any example using the feild will be so vast and detailed its pointless me writing it in any format other then abook! lol but i expect you should be able to apply this to your own game and the way you talk to your target so you dont offer to much but hint at other things. just making it a mroe sneaky subtle way to play.
best of luck
