件名: Chancellor and Pawn ending

I will have to annotate the ending of that game (I do not think it would be possible to annotate the whole thing.) I learned a lot about Chancellor and Pawn endings from it, and there are some new strategies for when to give up your checking sequence and allow yourself to be checked.

I am assuming my move 54...i6 is the source of some confusion. I thought about this move for a long time before making it. The rest of the game we pretty much played at a rate of about 2 minutes per move. We were both online and I guess we were both anxious of the outcome before CaissasDream went on vacation.

Here is the start of the difficult portion of the ending

white to move

This is where I stopped checking as black and allowed white to give check, only for his checks to expire at the moment when I could play ...Cd2+ which wins the b3 pawn and established 3 connected passed pawns on the queenside.

There is too much to write about here, but that is a good start.

I think the analysis of the chancellor endgame is not very important. You can see light that White`s positions becomes bader after Black`s rook invades in the white position with 40..Re2!and after 49.Cxg2 the position is probably
lost for White because he loses now many of his pawns and now with enough time of consideration it is only a question of Black`s technique until he can realize his win.
More interested is the question why the better position of White until the 38.Move now was lost!
Ed found a very good move with 38...d6-d5!!, so my move 38.Bh3-g2?? was a mistake and loses the advantage.
I have to prove a better move, which doesn`t White allow to play 38..d6-d5.
Better seems to be at first sight 38.Cf4!? or 38.Ce5!? Comments?

I thought the Chancellor ending was important since it is the first real life example of such an ending. Even the famous Rook and Pawn Lucena Position had a predecessor referenced in that book from over 500 years ago!

The Chancellor and Pawn ending we were in has no such predecessor -- it is the first such ending, ever.

You are correct in that 38...d5 was a transition of sorts in the game. In fact, you could argue black was losing the whole game by making non-developing opening moves, at one point in time with only two minors developed while all of white's forces were in play with the option to castle to either side.

After 38...d5 white did have the opportunity to equalize, but the pawn push b3 on move 44 is where I consider the position definitively lost.

black to move and win

I think Black was forced to take the bishop, allowing the chancellor check and then the recovery of it, leading to an equal position with white to move and deliver check.
