Commenting on solution:This is #629 in L. Polgar's "Chess" book with all the mates. I got this book myself early in my chess phase, but have had renewed enthusiasm for it since reading GM Jesse Krai's novel "Lisa" where it figures prominently. This one really stuck out for me as an interesting idea.Basically, you sac a knight, and black is forced to capture and has 2 choices. However, either choice blocks the action of the other piece and so allows the other knight to mate.I really like the basic idea of the distraction technique where the there are two options and either one blocks the other piece allowing the mate. I also really like that it's a little bit hidden because the first impulse is to try Queen checks first, because the reply is forced and that seems like a good start to a mate in two. So, it was only after awhile of trying to find a cool second move to both queen checks that I started looking for something more subtle and found this. So, I felt pretty happy and decided to share.
How to get to that Solution quick?You may calculate Checks First , a) queenchecks, b) knightchecks ..but even if then you have to have a Good vision .Or do we Start with the possible Matepattern and try to realise One of them?Or do we solve thaaat many puzzles that we simply Spot the Solution?
In my case, I checked all of the checks first. I gave up on the knight checks pretty quickly because they seemed to lose a move by just getting captured. When I had worked on the queen checks for a bit and found nothing I stopped and the actual idea of the puzzle occured to me as a concept. Then I had to check it out and make sure it worked. Maybe not optimal, but I'm fine with how it happened. I think I liked that it occurred to me as an idea rather than just as another move to try.
Often for me when I look at a chess position of any kind, my first instinct is to start messing with, start jiggling the pieces and as I do that, I start to learn things about the position. Eventually I feel I have an accurate enough picture and can start to try to come up with solutions to specific issues raised by the position. I think this method is quite slow though. So I think my chesstempo times are pretty slow because of that. With a mate in two its much easier because the options are pretty limited. So the jiggling can be quite targeted to begin with.
