I would love functionality as in the software "Chess Hero":
random pick of any position of games in the database - choose your move - move gets rated against engine's best move - you can pass to next position when you give up or score a move within a certain centipawn range of the engine's best move.
Of course you can stay in the position and check engine-suggested continuations of your input move, to see where it might be lacking.
This functionality doesn't exist anywhere online, except for in that program "Chess Hero" (found through google).
My chess improved drastically using that program. The best move in the position might be positional or tactical - you never know in advance.
