I composed this puzzle myself - enjoy! (mate in 6)
It was nice. Took me some time to figure out, but I need to do more puzzle like this one, where you trap the king.
Interestingly a couple of weeks after I composed this puzzle I reached a similar position in an online blitz game. However my opponent timed out and the game was drawn (although I should have won).
Nice puzzle, although this theme is very well-known.
Also, what happens if Black plays 1...Kg1? I'm sure that there is still a mate in 6, but what is it?
1. ...Kg1 2. Ne3
cool puzzle :)
Nice one. I need to do it again to understand well and find others like this one.
