Two good examples from the 2012 Championship. First a White win.

1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. g3 Nc6 5. Bg2 Be7 6. O-O O-O 7. Nc3 {Black is waiting for White to play cxd5 so his c8 Bishop can join the game after exd5. Black got fed up waiting so tries to sneak his Bishop into the game via Bb7.} 7... b6 8. Qc2 {Planning e4 or thinking of some tactical trick against the loose Knight on c6.} 8... h6 {No need for this. Rule of thumb No.431. If you play a move like 7...b6 intending to fianchetto then complete the fianchetto on your next move. I've seen 100's of losses attributed to a delayed ½ fianchetto. This is another.} 9. e4 dxe4 10. Nxe4 {Now complete the fianchetto. play Bishop to b7. Ignore the pawn on d5. The a8 Rook is trembling. Don't touch the d-pawn...} 10... Nxd4 {Too late.} 11. Nxf6+ Bxf6 12. Nxd4 {Black is missing a piece. At least he can save his a8 Rook.} 12... Rb8 13. Nc6 {Scrub that last note. Black resigned.}
Second is a Black win.
yournightmare - thaughbaer RHP Ch 2012
thaughbaer with a rather clumsy move 13th move (13…Rb8) drops the exchange. Though he will no doubt claim it was a sacrifice. I would 🙂
The Black Knight then takes over the game. First it hops all over the Queenside annoying Rooks. Then onto the Kingside to set up mating threats and other tricks. Meanwhile White is toiling to find ways to get his Rooks into the game. Just when it appears the breakthough in the centre is about to happen White walks into a trick kicked off with a Knight sacrifice.
The resignation is perhaps too soon. I would have played on.
Though the Queen v two Rooks is better for Black. I would still need to be shown.
