Which Engame Gives You Grief?

Escapest: there are quite a few pretty dances in R vs K mates for the quickest mating line that while are completely unnecessary are also rather attractive.

Grobe: it's possible to learn some QvsR technique. I wouldn't say I mastered it, but I think in a game I'd eventually force the win, which definitely wasn't the case a couple of months ago.

With regards to Q vs R, I presume everyone has seen the Philidor position. If not, I include the problem below which isn't quite at the Philidor position. Note that there is more than one good move on move 4, and I include a couple of notes on the move list after you've done the problem.

Good exercize again Marvellosity.  Is that also called the Philidor position?  The Philidor position we were discussing before involves rook and pawn vs lone rook.  I know there is that key Q vs R position which I only vaguely remember. I never know of the ethics in linking to other sites but here is a good general self-training tool for anyone interested.

And here is another specializing in Q v R

I find it frustrating as they don't tell you how to get into the crucial position, but good training.

I haven't used it much, but are some of these key positions possibly available and easily retreived from the Computer Workout feature here?

If not, I think some key endgame studies would really be a great addition to it.

Both my suggested links are a bit different.  The 1st lets you set up any position and tells you everything, all errors by both sides etc.  The 2nd is endless random Q v R drills with the computer explaining nothing, just making the best R move against your Queen.  There is nothing wrong with the various lessons here.

Escapest_Pawn, I assume this is what you are talking about?

yep, you got it
