in this position, i would probably play c4 to save the pawn on a2 and kick out the bishop

however i also see an opportunity for a discovered attack against that bishop, so maybe Bxg6 is better

EDIT: but probably not because black has Bxa2 and the rook is hanging, and white doesn't seem to have enough compensation

If ... Bxa2 then I assume you follow up with 2. Bxh7+ Kxh7 3. Qh5+ Kg8 4. Ra1 Bf6 5. Ra4 threatening Rh4 for a scary attack. You don't have a full bishop back but you do leave him with a massively exposed king and have enough active pieces to take advantage of it

For the people that suffer from rating anxiety:

There is this thing I do in most ELO based games where I have 2 accounts (might be against TOS, the lichess one was very vague) and bunnyhop the rating. Switch to queueing on whatever account is lower rated, that way losing won't feel as bad since you have a 'good' account left and you can freely spam until you top that one.

If you want to streamline it to not log in all the time is just be logged on one account on your phone, and the other on your PC or whatever

I just see that chess.com has analysed me as having played a few games at an estimated 1400elo and therefore that is my true rating even if my current one is 1069 and I’ve never even been above 1100.

The estimated elo thing is a bit weird, I think it has some kind of evaluation of how "hard" it is to see accurate moves, so just having high accuracy alone doesn't necessarily give you a high estimated elo (eg. a game where your opponent blunders a bunch of pieces and then a M1 doesn't require very high level play to be able to find the best moves), but at the same time it's never very clear why it thought a particular game was good or not.

The eval is heavily dependent on your starting Elo. If you import a game between 1ks, it'll give a well played game a 1300-1400.

If you import the exact same game but edit the import text to make the game between 2ks, it'll have the same well-played game a 2200-2300.

It's not totally blind, though, because if you pull the same trick but give each player 4k Elo, it just kind of breaks.

It's simplistic in some ways, yeah. For one thing it will seemingly always rate you higher than or at least equal to your opponent if you win, even if you barely scraped out a win by timeout after blundering yourself down to a king and pawn with a series of terrible moves followed by your opponent's internet going out before they can finish murdering you.

Played a decent game just now but ultimately I'm frustrated because I just don't know how to develop better vision.



White to play. This was a 15+10 rapid game.

I spent a couple minutes thinking what to play and then black resigned. Can you look at this and tell me your move and what your Lichess or Chess.com rating is. I'm around 1075 on chesscom and 300 higher on Lichess and my three candidate moves were Nd7, Ne6, and Bxe8. And all are winning, because black's position is terrible, but the clearly best move, the one that takes white from +10ish to +20ish, is Bb3. And of course I get why once I see it, but it's the seeing it in-game that is the problem.

Salt Fish

I'm 1400 on lichess rapid and saw all of those candidates, but I didn't manage to calculate past Bb3, ke7 in the 30s I spent on the move. Bb3 is a common pattern in puzzles where you use a discovery to take away more squares from the king. I looked for forks and skewers after ke7 and didn't see anything obvious, so then in that case I would take the exchange.

One concept I would apply here is that if you can reliably convert an exchange then its not wrong to take the exchange. Yes, +20 is a better evaluation than +10, but from a human standpoint you have limited ability to calculate, time pressure, and other factors. So sometimes you see a way forward that's going to convert and you can just go for it. Maybe not here specifically, but in general.

And of course I get why once I see it, but it's the seeing it in-game that is the problem.

I saw Bc4 rather than Bb3 which the engine seems to think is just as good (it likes the latter a little bit better though). I'm only 1021 rated on chess.com and don't play on lichess but I mostly play against bots rather than rated games because I always feel so intimidated against human players even if I actually have a pretty decent record against them. I didn't really have an idea of what I would do with that move but I did kind of have a feeling it might be the best one because of how forcing it is - the issue I see with Ne6 and Bxe8 is that both of them win the exchange but you also lose an attacker which makes it easier for the king to slip away. Nd7 doesn't have that problem and does have the advantage of only having one legal move in response, but it's also a "but then where do I go from here?" problem where it seems like the only thing to really do is make the same Bxe8 trade except now your knight is in a worse position.

For any of Bb3, Bc4, or Bd5 on the other hand, you create a situation where there's only one legal move for the king (which leads to a pretty easy to see forced mate), and the only other option for black is to block with their queen (where every available option will end up losing the queen or being a forced mate). Although like I said I didn't exactly see all of that (although I did have a strong feeling that there were a lot of forced mate lines in there) but I had a kind of gut feeling keeping all my attackers on the board was the best move. There are a lot of situations like this where if you put yourself in black's shoes, even if you're down material what you want to do is try to trade off pieces because the current problem is how many pieces are threatening your king and you need more maneuvering room. Conversely, as white, you can take the trade as you'll still be ahead in material but it gives up your very strong positional advantage, so you want to look for moves that allow you to keep all the pressure on the opponent's king.

Although all that said, you were already extremely winning so it's not a big deal to not find the most optimal move. It would have been just as viable a strategy to aim to trade off as much as possible to simplify into an easy to win endgame. There's a common problem a lot of players have at all sorts of skill levels which is "trying too hard to be brilliant" and ending up making a mistake because you feel like you should be able to win right now, rather than just sitting comfortably on your advantage and letting it win you the game in the long term. Playing it safer might be boring but it's a lot more reliable.

Oh whoops I missed Qf7. I spotted it when I came back to the position. That's just a specific category of hallucination that makes it hard to calculate where you forget that a piece vacated a square and now its available to be reused later during a follow up tactic.

Man that is like a puzzle position. There are so many potential forks and tactics that don't quite work.

I see the discovered check, I scan to see if there is a way to win a queen or major piece by moving the bishop, but there is not.
I see if there is a mating net but it looks like we can't cover e7.
I shrug and play Bxe8+.

Oh for sure, but this is just today's example. It's just as often that I have a couple candidate moves that seem like the best to me but they range from +1 to +1.5 and the right move would have given me a winning advantage. I guess it's the whole "when you see mate in one, look for better" I have trouble with. Or maybe I just have a blind spot for retreating moves.

another silly little moment from 5m blitz:



black is winning bigly, but white has a lot of pieces pointed at the kingside, and now black is in check. what would you do? how doers black get out of check and resume pulverizing white? there are three legal moves:

the good: Kh8 and white's attack is too slow. white has to move the rook to make space for the king to avoid mate in 1, but computer says it's mate in 13
the bad: fxg6 is what i played, and white gets a draw by perpetual check. automatically recapturing the pawn is a big mistake in this position!
the ugly: Kg8 is also good, but initially computer says not as good as Kh8, because white can play gxf7+ later. but leave it running long enough and it's mate in 12. funny!

how did you do?

Kh8 at least doesn't give white a check

Kg8, Nh6+ and I don't like any of what's going on; probably hangs a perpetual somewhere in here; Nf7+ I think doesn't work for him because Qxf7 Qc8+ but we've got a Queen covering on c1, depending on time and rating it's possible they hang it
fxg, Qxg6+ I think is just unavoidably getting mated

e: I can't find a draw out of fxg, Qxg6+ and any King move leads to Qxg7# ??

Kg8 Nh6+ is no good for white because simply Qxh6. instead, white still has to move the rook to avoid mate, but unlike Kh8, black can throw in an extra check later. but it turns out this doesn't matter because after Kg8 Rf3 comes the stunning h5! which can't be taken with check when the king is on g8 like it could be if he's on h8

Huxley posted:

e: I can't find a draw out of fxg, Qxg6+ and any King move leads to Qxg7# ??

note the presence of the queen on c7 and that the pawn on f7 disappears in this line, which allows black to defend against Qxg7+ with simply Qxg7. instead white plays Qe8+ and Qg6+ forever
