I will post the first position form the Chessbase site that I provided. White to move and find the best move Nd2! blocking the Rook and winning it with the White King in the next move Wink

[D]2rq1nk1/4bp2/4p1pB/Pp1pP3/1p1P2Q1/5NP1/1P2rPK1/RR6 w - - 2 1
   :: BR BQ    BN BK ::
::    ::    BB BP ::    
   ::    :: BP :: BP WB
WP BP :: BP WP    ::    
   BP    WP    :: WQ ::
::    ::    :: WN WP    
   WP    :: BR WP WK ::
WR WR ::    ::    ::    



=====================================================================================================================

The next position black simply play Nd7! and trap the White Knight:

[D]8/8/4kn2/3p4/N1pP4/1pP5/1P6/2K5 b - - 2 1
   ::    ::    ::    ::
::    ::    ::    ::    
   ::    :: BK BN    ::
::    :: BP ::    ::    
WN :: BP WP    ::    ::
:: BP WP    ::    ::    
   WP    ::    ::    ::
::    WK    ::    ::    



======================================================================================================================


Black to play, and most engines will find 27....Rxe4!

[D]2r1r1k1/3n1pp1/p2p1bbp/1ppP4/2n1PPP1/1P4BP/q1B1R1KN/1RQ3N1 b - - 2 1
