Wow, everything looks great everyone. I like the hints of green (the green in #57 and #59, not a huge fan of the greens in #46 and #33), I also like the canary in #54. not so much with the red tho, it's a little intense.
I also like the graphic on #57 and #59,
#61 has the advantage of simplicity and only b/w which means it'll look good on everything, it's very possible we choose something like these, a logo that represents kids/chess/premium chess lessons, with a logo we can use on ANYTHING, more like these!
keep the ideas coming, i'm having a ball doing this!
