Whitaker wuxuu ku dhex milmay muran la leh maamulayaasha shaakada horraantii 1930-yadii. Wuxuu aaminsanaa in loo dooran lahaa kooxda Mareykanka ee tartanka Chess Olympiad-ka 3aad
, Hamburg 1930 (halkii uu ka ahaan lahaa Harold Meyer Phillips (0.5/2 ee Hamburg) ama James Allan Anderson (6/17)), ama Olombikada 4aad ee Chess, Prague 1931. Iyada oo ku saleysan natiijooyinka tartanka hore, iyo bandhigyada daciifka ah ee Phillips iyo Anderson ee koox Mareykan ah oo sifiican wax u qabatay (meesha 6aad) ee Hamburg, Whitaker waxaa laga yaabaa inuu lahaa kiis macquul ah. Laakiin waxay u badan tahay in dambigiisii hore (eeg hoos) uu sidoo kale saameyn ku yeeshay go'aanka. Wuxuu si toos ah ula xiriiray madaxweynaha FIDE Alexander Rueb, isagoo soo jeediyay in laba urur oo isbahaysi ah oo Mareykan ah loo oggolaado inay xubno ka noqdaan FIDE, iyagoo u oggolaanaya laba kooxood oo Mareykan ah, halka waddamada kale ay hal kaliya leeyihiin, laakiin doodiisa waa la diiday. Qaabkan uu qofku u soo dhawaado madaxweynaha FIDE ee ku saabsan xulashada kooxda qaranka uma badna inuu ku guuleysto saaxiibo Whitaker. In kasta oo ay u muuqato wax aan muhiimad lahayn, su'aalaha ciyaartoyda ugu habboon inay ku ciyaaraan kooxda ayaa u horseeday maamulayaasha isboortiga Mareykanka inay qabtaan tartan isreebreeb ah oo ka dhexeeya Masters, si loo doorto kooxda qaranka ee Olombikada 1933. Waqtigaas, Whitaker wuxuu la kulmay eedeymo dambiyeed oo culus (eeg hoos); waligiis laguma dooran kooxaha mustaqbalka. Kooxaha Mareykanka ee aan lahayn Whitaker waxay awoodeen inay sheegan kooxaha billadaha dahabka ah ee Olympiad ee 1931, 1933, 1935 iyo 1937, oo ay weheliso billado shaqsiyeed badan. Sanadkii 1939, Ururka Western Chess Association iyo National Chess Federation waxay ku biireen United States Chess Federation.
