Question About the Catalan

Sort:
Ziggy_Zugzwang

Black can of course play dc in various positions. Sometimes white can recover immediately, and sometimes not. Should white always analyse towards being able to recapture in concrete variations, or is it enough that his pull hopefully leads to the recapture of the black pawn on c4 ? I find this one of the toughest opening ideas to untangle.

It's tricky for sure and it depends on the exact position of course but if you're not comfortable being a pawn dow for a while for "comp", you shouldn't be playing the Catalan...  :-)

Indeed. You are speaking in terms of Open or Closed Catalan. Weird. I think the Catalan is one of the most fearsome lines. Of course, there are equalizing lines; on the other hand, just concentrate on Open lines. Any one variation should be studied, to me. White enjoys a nice initiative. No need to overthink this is my advice. Experience plays a big part. As it is, cool...just play, my friend.✌🏽

Good luck if get anything useful, from that returning troll.

I think the second post was most accurate, The catalan is quite a complicated opening with white needing to be comfortable playing gambit positions, and subtle positional ideas exploiting weak squares on the queenside. Don't think the OP is ready for it to be honest.

Well I found the postings interesting and added to the debate.

When I read your suggestion that I should consider not playing the Catalan I considered throwing away my recently acquired Wojo trilogy. Nevertheless, inspired by your amazing powers of assessing my chess strength based on the question I asked, I looked up your chess grade. Lo and behold, I out grade you by twenty points. And yet your online rating is very high - hmmm

TwoMove

For somebody who has those Wojo books, it was quite a low grade question and a bit pointless because surely they answer this question and more. 

I am a FIDE 2000ish rated player, i.e a mediocre club player strength.  Considered playing Catalan myself at one time but didn't think I was strong enough. Can't find any OTB rating for you, if you are named as claimed to be.

It was a question aimed at generating debate.

2000ish FIDE is a stretch IMO.

Have to say looking at the quality of your online daily games, if you are really 20 points higher than me OTB, your not spending much time on the moves, you are drunk whilst playing or both. 

That's a different John Simmons, my FIDE rating is actual, but not based on many games. If you are if claimed to be there isn't much difference in playing strength. If find value in people posting games from database, you got what wanted. I'm not going to say anymore.

 Well perhaps I use chess.com as batting practice. To explore new opening. That must be you, since if you claim regular play you must have an ECF grading to play OTB tournaments.

Once again assuming I want to spend a lot of time on moves. I'm playing around forty at the moment. Who made you the arbiter of who should play what opening and how long they spend on game consideration ?

I'm also the webmaster of my club http://warleyquinborne.co.uk , so if you wish verification of my identity, I can call you a snotty nosed git from that email as well.

Catalan pawn sacrifice is too deep. Positional sacrifice is too deep to be seen as a mistake by powerful program like Stockfish. Stockfish accepted pawn sacrifice at move 10...... Qxd4??. and got hopeless game after 20 moves later.

 

This is a known pawn sacrifice variation by Leela.

Thanks for posting. Nice game.

Only an idiot would attach a double question mark to 10...Qxd4, which is a perfectly good move, and has been played by several super-GM's (and in a few serious ICCF games as well). 

You need to wake up to learn the changes in technologies. grin.png

Leela is at least +1000 elo above GM, GM are like amateurs to Leela.

 

All your ICCF GM used old version of Stockfish, so they do copycat of Stockfish mistakes.

 

Stockfish programmers already aware of it, it is still hard to fix for such mistake of Stockfish without sacrificing the speed. 

Bryan Stockfish is the main analyser of stockfish by doing reverse analysis.
