Good would be Nc3-e2 to pressure the bishop, followed by c2-c3 booting the bishop. The knight can then be further deployed towards the kingside at g3 where it also lends influence to e4.

Assessment: material +1 white, back rank development: white -1, black -2, center control favors black, positional placement of pieces is better for black than white because the pieces have more mobility, the bishop pin at f2 is a plus, the knight at f6 is a strong defender, the rook is ready at what may be a future open file. White has development issues becuse of the queen position and because of the incursion of the bishop at d4 which prevents f2-f4 or f2-f3. Both players have limitations on bishop mobility, but white has the worst scenario.

A tactical oversight. I have worked my way through many of these, still am, it takes practice to be able to see where tactics can work for or against you. * I highly recommend looking at the best games of Leonid Stein and Tal, 2 players whos games just astound me. Stein makes moves that just look impossible, crazy, or like a losing move, until after you react to them and it is all over for you. I recently got a book on Tal called Tal the Magnificient by Soltis and I am very impressed with the games. You can learn a lot by reviewing master games on a chessboard.

Play for white declines from here. In my losing games I keep playing on as strong as possible to give the opponent my best efforts out of fairness. I just look at it as good practice for finding the best moves when at a disadvantage. I usually play to the bitter end for endgame practice.
