It is the methodology used when searching for a key move. Here we are dealing with the elimination of the white pieces, which are certainly not eligible as a key move. What remains is a piece that does nothing for the mating pattern and this piece must move as a key move.
@@petersiegfriedkrug I assumed that the rook could not do anything, (and meet 2 moves), so I never thought of it after that assumption. Makes a guy with a couple engineering degrees, (not leave out factors in a problem), feel silly.
I'm not especially good at these puzzles, but this one I saw right away. I didn't analyze every possible black move the way you did, but I was pretty sure that black had no escape.
Interesting. This is very good solving fodder. As in a game, you have to eliminate the pieces that will certainly not act as a key move as quickly as possible. If you do this, you will quickly get to the remaining piece. For once, this problem is not a zugzwang problem, but a threat chess problem. I´ve solved it in about 5 seconds.
It is amazing, what we miss with our brains, even when thinking about it for only 2 moves. I find your chess vids make us think more than any other chess vids on YT. Outstanding sir! Someday, I will figure one out before you show the 2 moves. :) Doug in Michigan
It is not hard to find the solution. First you cannot move the king but one step backward. The queen has 20 possible moves only. The pinned rook can only move horizontally to 6 possible squares , while the other rook has 7 possible moves. That makes it only 1+20+6+7 = 34 choices only.
I just looked at the b1 rook moves first because going through all the queen moves can take a long time. Got it pretty fast but it was more luck than skill.
The one thing I learn from all of these puzzles is that I'm a pretty poor chess player. Of the dozens of puzzles I've tackled, I think I've correctly solved 1 or 2.
You simply have to go through the options and opponent's answers, and exclude the one's which don't work out. Since the condition is "in 2 moves", the number of follow-up moves to calculate is very limited, other than in an actual game. It's a logical chore, basically.
This one was funny. After a minute or so I couldn't find the winning idea when I got a low battery indication. I plugged in and after the interruption I saw Ra1 instantly.
Not too difficult. The white queen has no good move. The king only has one option, which makes no sense. That leaves only the rook b1, which also only has one sensible option.
I got it. I was like "ok we're probably going to need to sac the queen" and then "wait what's our second rook for ?" It took me a couple of mins but I was looking at it while eating too 😝
Didn't find this one too difficult. Thanks for all the puzzles! :)

It was surprising to ignore all the threats and still checkmate the opposite King!

@@Echekk Thanks! When moving the rook I could find it also. Updating the description now. Thanks again!
Nice as usual. Thanks
Excellent puzzle as always. Thank you very much
Actually managed to solve this before hearing the solution, neat :)
In 2-moves puzzles the first move should be: either extraordinary or too much humble😂
I only saw the winning move, and did not try anything else

For some reason, I saw it immediately. Usually not the case at all.
The bottom White rook is the least useful of the pieces in this position, so one can stumble onto the discovered check threat.
Man that is brilliant.
Excellent puzzle, thanks for sharing.

Actually got it right. First time in months.
I saw the move in seconds.
Spotted the solution in a minute or two. I love checkmating with a king move =D
I FIND IT ! I FIND IT!
In a real game I would probably just capture queen with check and take the free rook on h2 and be up a rook.

I guess that's why they call it discovered check, which I did not discover. Next time!

Yes sir!😊
Crap, out of all moves I didn't think of moving that rook
Same here.
I did think of moving the rook, but I could not follow up. Quite embarassing...
I couldn't find it. Great puzzle.
Got it in the end but it took me about ten minutes. 👍

Puzzles are different from playing a game of chess.

That rook killed itself with effort have to move all the way to a1. The lazy assassin.
Excellent
Я знал, что эта ладья не просто так там стоит, но до этого хода не догадался. Классная задачка)
Before watching thru: R to A1. (took me almost 20 min tho... I don't have much experience).
This one was funny. After a minute or so I couldn't find the winning idea when I got a low battery indication. I plugged in and after the interruption I saw Ra1 instantly.
Too sneaky for me :D
Great puzzle
I'm a little shocked, I got this in about 5 seconds.
I was surprised you didn't mention rook h3, but it doesn't change anything. Rook b4 is still checkmate.
With a pinned rook on b2, the only reply to 1. ... Rxb2+ is indeed the solution.
Yeah, totally missed that
Ra1- whatever black does, next move mate!#
Took me about 10 minutes. Pretty chuffed.
It took me 15 minutes, but i got it! Love the challenge of these puzzles.
I saw immediately the solution but without seeing the black rook in h2😂
Luckily I then realized it was good anyway😊
Fun!!
Took to a1

This was easy.
I thouhht easy cuz no other purpose with the R on b1
