Check out the game from move 50 on from Reggio-Emilia
K+N+B vs K
Great instructional for showing how to execute this checkmate.

P.S. Never mind, found it http://www.chessvibes.com/reports/gashimov-wins-on-tie-break-in-reggio-emilia/ . Black could have defended much better with 58. … Kd1 and forced White to find 59. Ke3 Kc2 60. Nd2 Kc3 61. Bd6! Playing as he did, Black should have resigned much sooner.
Moro’s position collapsed at light speed once the rooks came off. You look at the ending B + N + 5P vs. 2N + 5P and it’s hard to believe that soon, Ivanchuk will win all Black’s pieces and pawns for just his five pawns.
