I am looking for some advice and pointers on teaching young kids about endgame ideas. (Say for children ~8 years old). I am asking specifically regarding my nephew, but I have seen this happen to other kids as well. Often, they know how to mate with K+R vs K, K+Q vs K and similar.
In their actual games, they will get a good position (often even a piece advantage) and then they are just meandering instead of casting a mating net. Here's the interesting thing, if my nephew is shown a mate in 2 or 3, he'll usually figure it out. But in his own games, he seems happy to just keep making the moves.
Any suggestions and link/book pointers from parents, coaches welcome.
