Expanding the use the tactics trainer

Just wondering,

lately after finishing a tactics puzzle, i sometimes try a finish off the game using the finish Vs computer Icon. When i make a weak move, i simply restart the puzzle and play until the next weak move i make, then i restart the puzzle again. eventually i can play from the start of the puzzle to checkmate flawlessly. i seem to be learning a lot from this training. 

basically, i'm practising a won position against the level 10 computer

Has anyone tried something similar?

They have offered that as "drills" for years.

I guess their letting people use any position for that type of training is new.

I haven't done this but it is an interesting variation on tactics trainer. I'm pushing more time into Tactics (puzzles on chess.com/working through bobby fischer teaches chess) at the moment and this may be a way of optimising training time.

An alternative idea I have inspired by this (where puzzle is not a checkmate - or you have missed checkmate) might be to force yourself to load up the position of a failed puzzle and play it to conclusion against a computer of comparable strength (L5 for me). This would provide a consequence to getting this wrong and make you work to recover/demonstrate why your choice was a poor move.

The drills section is interesting and not one I've looked at before. Thanks notmtwain.
