4.Nbd2 is not a bad move, but it's committal for no reason. I like Bd3. The point is maybe the knight will get a chance to land on c3, which is a better square. Maybe its destiny is on d2, but by deciding early in the meantime you block the bishop.
5.c4 is not bad, but I'd rather break with my a pawn, which is really just as good but has the added benefit of getting the rook into the game.
9.e5 is not bad, but it opens so many light squares, really not a move worth looking at here when development is still an issue IMO. Maybe later it will be good, but all it does here is waste time, give your opponent more options (the light squares) and you fewer options (your structure is static).
10.Bd3 is bad though. This is a bad diagonal, and if the plan is Be4, it is a plan that wastes a lot of time, now black gets ahead in development. (It's also not a good file, remember bishops tend to block files, and here you'd rather a heavy piece have access to the d file).
Better was any move related to getting another piece off the back rank.
11.Be4 continues to waste time.
12.Nc4 lost the game, the end :p
This is a game I played
pls analyse it for me :) Thank you in advance
