Find the right winning strategy as white!

[@brettmccann3403]

My apologies to Emanuel Lasker for yesterday's arrogance (albeit tongue-in-cheek). I didn't come close to solving this one. Talk about out of one's league. Mr. von Bargen, thank you for the lessons in both chess and humility.

Thank you so much sir, you are a saint!

[@brettmccann3403]

@@Chess-strategy Perhaps, but I'm certainly not the patron saint of chess! You are very welcome.

It takes a bigger man to admit he was wrong than to insist that he was right. Well played.

Thanks

Thanks a lot! You're my hero ❤

There should be a time stamp in the vid separating all the wrong variants from the right solution!

[@rogerkearns8094]

Busy life, eh? ;)

[@fireworxz]

Yessss, agreed

[@mauijttewaal]

Well what about almost at the end?

[@MatthewPierret]

Very proud to say I found this making it three puzzles in a row, especially since I initially had no idea what to do. Doing these puzzles every morning has really improved my thinking over time. Thanks!

[@rogerkearns8094]

Nice domination of R by B, not easy to find. Thank you.

[@mauijttewaal]

R by BpK...

[@ismailabdelirada9073]

The defender's king position -- so remote that it looks irrelevant -- turns out to be his fatal vulnerability. Because it is on h1, a _white square,_ it enables White to control the entire eighth rank.

[@RamKumar-gy9nb]

Excellent thought process, thats what I keep learning in each of your puzzles. You teach us the thought process behind a strategy which is required in real chess games. Thank you very much and God bless you.

[@UteAllef-wo5uj]

😂yes, this is what I thought, it ought to be... I really almost had it and came quite close. One of the things I can do best, is surely to let other people do the right work for me 😂 this one is great😊

[@giovannicorno1247]

Missed😢. I tried other moves with the same piece but I didn't consider that in the correct variation there is a double attack😤. Nice theme of domination!🙂

[@TwoHeadedMeerkat]

1:45 What if you move the bishop to e6? Threatening a potential check on the King while threatening the Rook directly? Could you chase the Rook down with the King and attempt to fork them both with the Bishop if they try to retreat to the left corner?

[@FireCrack]

I found this, though I have to say the low number of valid starting moves helped! But still this was a really fun one!

[@FritzchenBox]

Tolles Rätsel! Danke

شكرا🎉❤

[@drjaigupta]

A bit tricky but able to solve it in 5 -6 minutes. Is K e6 correct choice?

[@Jared7873]

Yes

[@gokceaydin3324]

Well, I made a trial and Stockfish with a queen only could not defeat itself with a rook only. Stuck by the 50 move rule.

[@rohdri]

Thankfully humans generally can't do perfect play

[@mauijttewaal]

It's tablebase, nothing to calculate...

[@ismailabdelirada9073]

​@@rohdri: Even if they did, Q vs. R should be a win. A grueling win, but still a win.

[@rohdri]

@@ismailabdelirada9073 Should be, but really? It's not so clear cut. You still have to pin the king somewhere, and that's a tricky thing, especially if you have to protect your own king. Now, if it were a bishop vs a queen, I'd definitely say it's only a matter of time. But against a rook? 50 moves is possible, and you can play for a draw.. Most humans couldn't pull it off, but a computer?

[@ismailabdelirada9073]

I've been playing for fifty years now, including tens of thousands of blitz games, so what I say reflects my experience, as well as the theoretical understanding that, with reasonable play, the win takes an average of 31 moves. Now, of course human players err, and that's why I say the win is grueling to bring home, but I have had to do it anyway, and I did find it possible.
