The course is rather frustrating and not solidly worked out. Correct moves are given as "incorrect", without clearing variations, and equally easy winning variations are also given "incorrect". There are no variations at all in this cases. For exampel:lesson 2: 1..Nb7, 1..Nc8 etc. are given "incorrect", although in no means worse than the move, given by the author.lesson 3: there are, in my opinion, many ways to win, but all others than the authors choice are given "incorrect", without variation at all.lesson 7: 2..h7 and diverse Night-moves are all correct and not weaker than the authors choice, but given "incorrect".After that I decided to skip the course and post a comment.Very bad course, surprisingly, after the part 1 on the same subject from the same author was great! Sorry, when I overlooked something, but I had the feeling, the further course would go on in the above described way and I decided to save some time for more useful study.
Seeler, thanks for your comments and pointing this out to us, with those details. i have no idea how these glaring errors slipped through my supposed editing process. the course will be updated/improved/edited, and i'll make another post here when it is.
Hi IM dpruess,many thanks for your reply. I´m very glad that you are ready to check the material and if necessary make some updates. I can add, that I checked the new course of GM Bojkov, Night Endgames (Part 1), and I can say, this course is also great, as Knight vs. Bishop (1), so this indicates additionally, that in the above mentioned course something must have gone wrong. I found the courses from GM Bojkov on these subjects very instructive and i hope he will continue this work for us in the future.
i see i'm not the only one having trouble with this lesson. when i play this one against the computer using the link at the end of the lesson, i can't win unless it's on easy. after 1...Ng4 per the lesson, white moves 2. Bd3 and wins. black never gains the tempo needed to promote before white. the variations mentioned don't seem to be losing for white either. i understand black may have won that game but the lesson seems kind of lost on me when white apparently had better moves and could have won the game. i'm just a beginner, so perhaps i just haven't found a way for black to win this position against a strong opponent, but it seems white always finds a way to block black's a pawn and promote its h pawn.
which lesson vparty?
same one, called Barrier, #KVB003
here's what happened when i played this position out vs the computer:
Ng4 Bd3 Kb3 Bc4+ Kb2 Kd3 a3
now the computer realizes that it can't stop the a-pawn, and it can't do anything anyway. it played
Ke4 Nf6+ Kf5 Nxh5 Kg4 Nf6+ Kf3 a2 Bxa2 Kxa2 Kf1 Nxd5 etc...
ok i get it now, i see how the knight bars the king from supporting the h pawn and white cannot stop black's a pawn AND promote its h pawn. i was able to win the following lines:
...Ng4 Bd3 Kb3 Be2 Ne3 Kxe3 a3...
...Ng4 Bd3 Kb3 Bc4+ Kb2 Ke4 Nf6+...
...Ng4 Bd3 Kb3 Bc4+ Kb2 Be2 a3...
...Ng4 Bd3 Kb3 Bc4+ Kb2 Kd3 a3 Kd4 a2...
thanks for your help IM Pruess i appreciate it!
