Clojurians Log v2

Great session yesterday at Thoughtworks. Our group did Tic Tac in Clojure: https://github.com/TomSpencerLondon/Clojure-Tic-Tac-Toe I am being a bit slow on this code: https://github.com/TomSpencerLondon/Clojure-Tic-Tac-Toe/blob/master/src/tic_tac_toe/core.clj#L16

I understand game and full-row and first two lines of check. Just wondering about lines 20 and 21 in check method. Thanks!

Most peoplw switched from this channel to #clojure-uk several years ago, so its not very active, although there is still 128 members of this channel. Feel free to use this channel if its valuable, but most people (456) are on #clojure-uk. Thanks
