Bihar chess also sustained a setback on 3rd April 1983 when the two factions of Bihar State Chess Association split and held their elections separately. The matter even went to the Hon’ble High Court which ruled in favour of the faction led by Dr. P. N. Sharma & Rupendra Narayan Sinha because they submitted documents relating to the election of their faction to the Registration Department and had obtained its certified copy. But the AICF had in the meantime recognized the other faction led by Prabhakar Jha and Premendra Kumar. In view of High Court judgment against the AICF recognized faction, it resolved to change its erstwhile name from ‘Bihar State Chess Association (BSCA) to All Bihar Chess Association on 26th January 1986. In 1985 Muzaffarpur Disrict was brought into existence by Rajiv Kumar Sinha, a local chess enthusiast from Muzaffarpur. By his efforts several All India Rating tournaments including National Under-25 and National A was conducted at Muzaffarpur.
In 1978, for the first time, an All India Open Chess tournament was organized in Bihar under the banner of Magadh Chess Club whose Secretary, Rupendra Narayan Sinha. RN Sinha was among official founder members of Bihar Chess Association.
ABCA organised National Under-25 Chess Championship in 1988 under the leadership of Dr Amaranth Singh and Prabhakar Jha (both from PU) who were ABCA President and Secretary respectively. Later, as it appeared, they lost their interest to continue in Bihar Chess and paved way for AR Khan in 1991. AICF did not accept this change of power though it continued allowing players from Bihar in the National events.
In 1992, National A Championship was again organized in Patna (Bihar) but in a typical way. AICF Secretary PT Ummer Koya allotted this championship to Bihar appointing Navin Kumar Upadhyay, a chess player and a journalist. The championship was successfully organized under the leadership of Tripurari Sharan,IAS, However, PT Ummer Koya discreetly recognized A R Khan and ensured Bihar’s vote in the 1993 AICF election he won. Once again around 1996, all most all leading chess players stood united and revolted against A R Khan to the extent of holding a parallel state championship, but that proved futile in the light of the fact PT Ummer Koya continued supporting A R Khan uptill he himself was ousted from Indian Chess in 2005.
