I was thinking allong the lines of Nc4, or even Ne1 or Ng2 to reposition. Stockfish thinks very simmilar, it suggests Be2, Bg2, and Nc4. It was constantly switching between the three, and ended up with Nc4 being the best move.
Whites plan is to move the E knight to c4, e5, d3 and then to c5
Blacks pan is to reposition pieces bishop to a7, bishop to d7, and then to e8, then black will open the position with b5 and f5
White will respond by taking controll of the center, he will use his knights to block the position to keep it closed while posting his knights in avangious spots. E knight going to c5 and if f5 is pushed white will take and reposition his other knight on e5. If white has time he will reposition his D rook on b3
Black will respond to theese knight on c5 and e5 with his own knight in the middle on d5. With the position closed, black will start pushing his kingside pawns, allong with advancing his king.
White will respond with bg2 attacking blacks center knight.
