}

check1 до check3 не са от най-добрите имена на променливи :). В случая, може би ще е по-четимо просто да не си правиш отделни променливи за тях, а да сложиш проверките в клаузите. Иначе няма как да прочетеш тези if-клаузи без да скачаш няколко реда по-нагоре да се консултираш със "чакай, какво беше check1?"
