Born into an Angolan coffee-growing family, Bis turned his trade into a global export business, and the same patience he brings to sourcing *arabica* and *robusta* cherries shows up in his play. His repertoire leans toward classical queen-pawn structures, and as White he often steers games into the [Queen's Gambit](/resources/openings/queens-gambit), preferring sound positional ground over fashionable theory. He rarely blunders, calculates accurately in quiet positions, and converts small advantages with the precision expected at master level. Opponents who sit down across from Bis should expect a calm, technical fight rather than fireworks, with mistakes punished cleanly and endgames played to the last pawn.","58","NihVk","Angola","ao","ee93136aba54557e0aa6511162fcd2fd36dc8496011951380df223357d9f7f34","2026-07-06",2449,"json",[15,18,21],{"question":16,"answer":17},"What rating is Bis?","Bis has an estimated rating of 2449, placing him in the national master to FIDE master range.

Strong IMs and GMs will score reliably, while peer-strength masters can expect roughly even results.
