After the queen captures the d pawn, Nf3 doesn't work because Qe4+ wins the bishop with a fork. The better move is Qf3 instead of Nf3 because Qe4+ would hang a queen.

Decided to upload this one without any edits. Let me know what you think. I did not add a board to this one as it obscured the background of the cafe with loads of games going on. Let me know if you prefer this or if you would like a display board instead. I am open to suggestions on the format as it is very new.

Awesome sacrifice 😮 Thank you for sharing this 🙏

That guy makes the chess looks so easy and fun…I love the way he plays 💪

That was brilliant 🤩

Sorry for the rubbish video quality. I am going to use a tripod to record next time on landscape instead of portrait. Hopefully include some more post game analysis. Still an awesome game by Cristian!

Also: Ka5, Ka3, Qa4 mate

Easy

Not very difficult

How can you rate this to be one of the hartest checkmate in two. It's one of the easiest mate in two puzzles I've seen.

Instructive, but your A.I. subtitles suck!

2:46 7...Nf6 is also possible and after 7.Qh4 hxg6 8.Qxh8 Qxe4+ 9.Kf1 Qxc2 10.Nc3 Kf7 with a strong attack.

Who in the world plays D4 and then C4 to begin with

Ugh. Lots of annoying, beginner-esque commentary mistakes - calling out wrong pieces, wrong squares, and the wrong color on the move. Why is that so difficult to get right?! Great games, though!

Too easy. I saw 1.Rd1! Always if it smells Zugzwang, you can try a waiting move. This is a chess problem for beginners!

I solved it in 6 seconds!! Not longer. The key move is 1.Bb1 and then the rook goes step by step... Note: In a chess problem with view pieces on the board - very often you solve the problem by thinking on Zugzang. Actually only b3-b2 is possible. Therefore you have to find against this ...

This is one of the exceptions where it wins. The reason for this is that the black king is on the edge and the black pawn prevents the black rook from getting better squares faster. This position is posted on the Internet on KZfaq by other people again and again!

Much, much too easy Andrew! This are forced move. The rook must act quickly! The mate is easy, because the white King already is near the edge. I would say, for beginner this puzzle is okay.

Really beautiful. I saw 1.Qd4, but there is ...Bxd3+ because the w. bishop on a5 is undefended. Therefore 1.Qf2! It is very rare that I do not solve mate in 2 in about 1 minute or 2 minutes. He was so fantastic!

Famous study which I knew when I was 12 years old

1.Qc2 second 2.0-0 # I solved it in about 4 seconds. It is an extremly easy chess problem!!

Very, very easy. I solved the queen sacrifice in 3 seconds.

The black pawn on h5 is not necessary. Without this pawn on h5 it is also won (1.Kh5). By the way. the pawn pair e6/e7 can also be on the d file, or c file, or b- file, but not on the a - file for sure.

The second puzzle I believe it is by the famous study composer Mario Matous. I like his studies.

Famous problem. I think it is by Sam Loyd, is´nt it?

I just did the pitc defence

This is BS. How can you possibly know that castling is still available?

But which one? Is it white or black? Please make that clear

2:26 What if, instead of Qd3, white plays Bxc6 with the intention of trying to capture the pawn on e5 next?

10:33 that problem pointed out an issue in your calculation. You assumed the queen had to move after the rook sac and Rg1. The queen can stay guarding bc white is already down a rook and needs to give up another to win the queen.

Very informative

what about Nf5 if ... Kc5, Qc6 or ...Ke5, Qd6

I don't really like these castling puzzles, unless it's obvious that castling is still an option. I did figure this out on the second attempt. The first move I figured out pretty easily, but the castling took one mistake. A surprisingly quick solve for my rating still, my puzzle rating is only 2000.

Am I mistaken that I thought castling across a checked square is illegal, even if the king doesn't cross it?

what a beauty

Dang, these almost always get me. If I had actually played the game I would have known that I had the castle option. I gave up to soon on this one.

I'm a sicilian defence player, but started to play the Nimzowitsch 2 weeks ago. I also play the mexican defence (Tango) against d4, and didn't realize until now that they are almost identical.

I'm wondering if this defense will still be called "modern" in like 50 years

Great explanations. I used to dread the Petrov Defence, but now that I understand it, it doesn't really look that bad anymore. My dad usually meets 2.Nf3 with 2...Nf6, and I always feel uneasy when he does that. I can't wait to apply what I've learned from this video against him. 😁😈 Thank you!

I love when under promotion is the best choice

Hello

#6 Change the chyron's notation to include b5! Please remember this is chess and details matter!

I tried to do the King's Indian but the analysis said its the Modern Defence so now Im here. I didn't know they both put the bishop into the longest diagonal.

It's a good thing I couldn't figure this out years ago. It was so easy the 2nd time around.

This took me a number of minutes. fun problem.

No one open like that 😂

Problem 26 you start off down a piece and you are sacrificing an exchange on top of that. I think the key to that one is the evaluation of the resulting position after you win back the piece. You are down the exchange, but you didn’t mention why you were trading down into a material down situation.

7:55 How ist here no rush for white? What about Kh3+ discovered check! Looks like this stops the pawn because the square g2 is covered.

brutal! Congrats for the explanation and for the clarity

Bullshit puzzle. There is no way to know that Castle is still legal at this point in the setup.
