Some of the scenes felt rushed plus I never really cared for Bobby Fischer to begin with, but if you aren't sure what to watch and like chess then it's pretty decent.

https://www.imdb.com/title/tt7494416/ Closing Gambit is a documentary about Korchnoi vs Karpov. It features a bunch of GMs from that era and was pretty good! Main issue is that its very "history channel" in its presentation but I can live with that.

Is there a significant difference between how Chess.com and Lichess assess ratings? I've been struggling to get out of the 800s for Rapid games on Chess.com for awhile now, but on Lichess after playing for a bit I've landed around the mid-1300s for rating and I'm not really feeling that much of a difference in the difficulty of the games -- if anything I've been doing a bit better there. Just curious if there's anything to that or if it's just a string of luck.

The same skill rating on chess.com equates to a couple few hundred points higher on lichess it seems. Whether this is due to a different rating algorithm or just due to a different population of players with a similar algorithm I don’t know.

Rating systems can't be compared across different pools in general. Lichess I think starts you off with a higher rating which obviously affects the numbers. I think at ratings in the 1000-2000 range Lichess ratings will be 3 to 4 hundred points higher, but it levels off at higher ratings and eventually Lichess ratings will actually be lower. Rapid ratings also tend to be higher than blitz which are higher than bullet due to the different player pools (also your rating will probably change if you switch time controls within the same bucket, eg. 5+3 to 3+0). Which is to say, only compare within the same time control on the same website or you'll get conniptions.

On chess.com the default rating is 1200 iirc, never looked up the median but it is probably also 1200.

You can get an approximate idea by looking at the rating distributions for particular formats. It's not going to perfect of course but you can see what the percentile numbers look like: https://www.chess.com/leaderboard/live https://lichess.org/stat/rating/distribution/blitz

Another question on opening moves the online engine doesn't like: https://lichess.org/z48Ltt2V/black#12 This time it's a bit more ambiguous on whether the move is good. The masters database has 6... e5 being very rarely played (with very good results for Black, but it looks like it might just be one guy's pet variation?). In these cases where top players don't play a move, is it usually because it's "bad", or just unpopular? More generally, are there any hard principles on when to play e5 vs. e6 in these Sicilian positions, or is it a matter of knowing the theory? I can see how here e5 weakens the light-squared diagonal of the White bishop. But then why is e6 the move against 6. Bg5?

This is all about control of the d5 square. Basically, as black, you only want that d6-e5 pawn structure if you have a definite way that you're going to be able to push d5 (or otherwise take care of the square) in the near future. Otherwise you will suffer tremendous violence as white uses the square to throttle black's entire position.

Ah, so 6. Bc4 directly attacks the d5 square and 6. Bg5 indirectly does by pinning the knight, so e5 is too weakening. But White's other moves don't help control d5, so e5 becomes the main move. That makes sense.

Ugh, important safety tip re lichess: There is a setting under "Game Behavior" to "Scroll on the board to replay moves" and I've lost at least a few won games because I had this enabled, and short on time, accidentally scrolled my mouse scroll wheel to roll back a few moves and flagged while trying to figure out how to unfuck it (You can forward arrow your way back to the current position lol).

Iirc it only scrolls if you're over the move history! You can go forwards/backwards with the mousewheel, or do left/right on your keyboard.

I wonder how much psychology matters in classical chess because online it's gotta be a huge factor. I've found that if I beat a significantly higher rated player and they slam rematch immediately I should take it because it's likely to be easy wins for several games in a row (and free cheating accusations)  Since I don't want to be on the wrong end of that I pretty much never click the rematch button.

i never ask for rematches and almost always reject rematches for purely psychological reasons. i know there's no reason to assume any particular motivation behind my opponent's request but i always assume the worst, picturing either some vengeful, bitter opponent or some smug gently caress confident of another win against me. it's just easier to dodge the pschological minefield i've laid for myself and take a fresh, random opponent.Redmark posted:I wonder how much psychology matters in classical chess because online it's gotta be a huge factor.

- Solve chess puzzles daily to train your ability to spot tactics. Doesn't have to be long, 10-15 mins - Play longer, rapid (10 mins) or even daily games, as endless bullet/blitz doesn't help you improve much - Watch youtube videos by strong players, Daniel Naroditsky's speed run playlists are excellent and ChessNetwork's beginner to master playlist explains some useful concepts.

not sure how much of this is applicable, but it does sound like you might be starting from the bottom. if you leave pieces hanging, or don't see when your opponent's pieces are hanging, keep drilling with puzzles and focusing on seeing the whole board before you move until you see the hanging pieces 99% of the time. if you're in a low elo bracket, just being able to do this consistently will yield significant improvements without you having to learn anything else if you're at that level already, continue developing your tactics with puzzles, and start studying your end games and basic checkmates. focus on being able to checkmate with 2 major pieces, or 1 major piece and the king, every single time. then learn how to simplify into those positions when you have an advantage. you should learn the basics of opposition and how to win a king and pawn endgame start getting familiar with opening principles (not memorizing specific openings, but understanding what kind of things you want to get out of the opening, and what you want to avoid)

Got this video randomly recommended on Youtube which I think is a pretty cool puzzle: https://www.youtube.com/watch?v=kDkIo90kOwE The logic is obvious once it's explained but not so clear when you first see it. I never thought about it but there are probably a bunch of chess puzzles which utilize the rules for something other than finding best moves.

Thanks for that, really cute puzzle. Knowing in advance that there's only one square the king can be on helps with working it out because you realise it must have had to capture something otherwise there's multiple options

Unless I'm missing something it's not asking you to sacrifice a piece, but rather complaining about Be6 which hangs the knight on c6 (and a fork) and wanted you to trade the white bishop with your knight instead.

I wonder if you're reading the notation Nxd5 and assuming "d5" means a pawn because that's how pawn moves are notated It's not necessarily intuitive if you used to use old style notation (NxB) back in the day, but this is how algebraic notation works. The piece on d5 is a bishop and it's telling you to exchange your knight for it. Also in algebraic notation the letters and numbers are absolute and don't correspond to different squares depending if you're playing black or white, like "N-K4" did. Look at the little numbers and letters on the edge of the board. Sorry if I'm wrongly assuming. I learnt chess from books written in the old notation and took a bit of time to adapt.

See that lovely rook that now has nowhere to go and nothing that can move to protect it? The white queen can move to the noted spaces to capture it, also letting the bishop out to attack the pinned knight

Yeah. Qd5 is the only move that would protect the rook but that blunders mate in 1.

I'm sorry, I don't think I understand--if I move my queen to either of those spaces the rook can just take my pawn directly in front of it right? I really appreciate the help, let me know if I am posting too much. I was ahead in the 3 games I played today and the app categorised them all as Giveaways. I step on a giant rake every single game when I try to transition from defense to offense.

I suspect the line the computer is giving isn't actually about winning the rook, but rather going after black's awful king. Something like 17.Qe6 Rxc3 18.Bg5 Nbc6 19.d5 and black is getting mated in the middle of the board.

Lol you're right, I saw Rxc3 while trying to figure it out and then forgot about it, shameful. Anyway listen to Hand Knit, he's the strongest player here (FM I think?) What site are you playing on? You can probably find a way to display and play out the lines the computer is thinking of.
