danielsmidl vs kharv
What we did find is that the 12... Nb6 move is a pretty clear mistake since it obstructs the movement of the Queenside pawns, which is where I should have sought counterplay.
Then there was a way to save the game and even get an advantage with 20... Rd4, hitting the Queen, and picking up the d5 pawn on the next move with Nxd5 which also secured the tender b6-square and prevented White forking my rook and Queen.
