Wing Gambit (Read if you want points!)

Hello, the first  person who posts a detailed description on what the wing gambit is, how to counter it, and it's pros and cons wins 5 chill points! Btw, please do not copy other place's content. However, you can use info from videos or websites but use your own words. I expect this post to be quite long(because it is worth 5 chill points). Please post it in the comments. Thanks! Good luck guys!
