The 45-year-old two-time Malaysian Open champion delivered the strikes needed to win the match with 204 and clinched the title to give Thailand the double.
The champion did the same trick in the semi-final match against newly-crowned Thailand Open champion, Lee Ik-Kyu. Lee had failed to spare pin 10 in his last frame which gave confidence to Kritchawat to strike home to win the match, 218-202 to reach the finals.
Kritchawat beat the first Korean, Cho Young Seon by a single pin, 237-236 in the first round and then ousted compatriot, Dechochai Tinjiratip, 245-215 in the second round to advance to the semi.
The runnerup beat Hussain Al-Suwaidi of UAE, 243-172 in the first round and then compatriot, Gang Yu Chan of Ulsan City, 199-160 in Round 2 before thrashing Badin Lerdpiriyasakulkut, 277-237 to reach the finals.
