Really? Like what? I am playing these lines!

Watched the series up till this episode...verdict: Good general story..but...very sloppy in details.

You should engine check your comments/tactics when making a video.

MANY big errors... according to strong engines.

I must say I absolutely love IM Trendle's videos; I'm not sure if it's the accent or what, but I feel lik I could listen to him all day - and I don't even play the French!

Really want the next one in this series :)

good video on french variations.

Great video.  Explanations were clear and you answered the questions most club players would have at each step.  Interesting opening. Thank you.

This was a very good attacking strategy

With the way the opening went for White (badly!) I think Leko just wanted his King out of the centre before Black got to play ..e5. If instead of 0-0 if Leko had played say Qd2 planning to castle on the Queenside then there's not a good answer to ...e5 in that position.

In retrospect given the strength of black's king-side attach is White's king-side castle a given? What is the downside of O-O-O for white?  

True BrendanT. It doesn't change the assessment of the position just before. Black should castle Queenside and then play f6 to avoid the Qh5+ trick and the position is better for Black.

it's

 fine

As you continue this series on the French Defense, I hope that you will cover at some point a line in the Exchange variation 1.e4 e6 2.d4 d5 3.exd4 exd4 4.c4!? which can lead to rather sharp play.

At 6:43 you say the position is fine for black; however, after 1. Qh5+ black has to give up castling rights because 1... Qf7 is met by 2. Nxf6+
