You can definitely apply, but don’t be fool by the GC comments/confidence. Cornell probably a bit easier and “friendlier” vs Brown. Couple of things that are in your way - 1) GPA (weakish for these schools) 2) SAT (how much better vs PSAT - 15XX will get your cross the threshold - how bad is your Math or are you just humble - most Asians will have 750+ in M when they apply to these Ivies) 3) Hook - what is it - is Chess sufficient? People good at Chess are obviously “strategic”, “critical”, and “observant” - are those traits demonstratable in your other ECs? 4) Unfortunately, you have an “anti-hook” (esp. for the Ivies) - Asian/Male. Other than that, what is your intended field of studies? Non-STEM majors would be a way to avoid the Asian/Male “anti-hook” - but is that what you want? Can your feeling with Chess tie to the intended majors like History (many historical events, decisions can be examined thru deep strategic critical thinking!!_) Overall, I think you can apply to these two, make sure you have many other names in the Top25 to Top50 schools to consider. The smaller top liberal arts colleges may see “fewer” similar candidates with your profile and you have less an “anti-hook” there. Good luck. JMHO.
