Issues and features

[dav1312]

Issues

• When using multiple engines, the eval bar can get crazy if the engines have very different evals
• The first time the analysis board is opened, the coordinates don't appear #229
• Engine lines are always displayed after changing tabs #232
  
• Wrong file missing error in all engines
  
• It's not possible to change the number of lines of chessdb
• There is always an "Unknown" player and tournament in a database #144
• It's not possible to disable cloud engines from "Your engines" #145
• Check the opponent's threat is broken #143
  
• Use move history instead of fens
  position [fen | startpos] moves ...
  This helps with / fixes 3-fold detection
• If an analysis is running, and database moves are pressed, the analysis doesn't update the position and the engine will still analyze the original position
• Automatically detect available engine settings #132
  The uci command also outputs all the available options with their type, and their default values. Sending the engine options that it doesn't support may cause unexpected issues.
  Something that would be cool is adding a button to select a file from the computer if the option has "file" (or "File") in its name.
• When a pgn starts with black to move the moves still start as if it was white
  e.g. loading:

  [FEN "rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq - 0 1"]
  [SetUp "1"]
  
  1...e5 2.Nf3 Nc6 *
  

  results in:

  [FEN "rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq - 0 1"]
  
  1. e5 Nf3 2. Nc6
  

• The pictures when trying to load the engine are stretched. Might require to be inside of a div with text-align: center.
• App crashes trying to enable Stockfish
  
• Minor border issues with the last move color. #95
  Prettier lichess deals with this using overflow: hidden to the chessboard. Chess.com doesn't deal with this and just has a very small border radius which makes this issue imperceptible.
  
• Disabling an engine doesn't stop it #91
• Sorting the games of a database tournament by date or ply count doesn't work #90
• Komodo issues with 1 line #89
  When using just 1 line with Komodo, the info doesn't update. The engine works fine in the logs.
• When loading from a position, the PGN should have [SetUp "1"] #88
• PGNs should end in either *, 1-0, 0-1, or 1/2-1/2 #87
• Engine options are sent every time even if they don't change #81
  This causes some issues like, in Stockfish, clearning the hash after every position which means the engine doesn't "learn" about the game.
• App crashes when trying to go to the Database tab without a reference database #62
• The app crashes when Edit position > Empty position #16
• Fen Editor has incomplete and incorrect information #12
• The engine settings reset (visually) to the default position when changing tabs #39
• If you try to analyze a previously analyzed position, the eval and depth don't update until you get a to higher depth (even if intentional it doesn't seem like a good idea)
• It's not possible to make reports of games that start from a specific position #18
• If the engine PV is too short, the PV can get misaligned #22
• Don't let the user select more cores than it has available #35
  navigator.hardwareConcurrency
• The picture for the Komodo default engine should be Komodo, not Komodo Dragon
• The engines have a scrollbar in their edit engine modal #33
• The queen is being valued at 8 points #28
  
• The flip board button doesn't work the first time its pressed. #20
• The WDL results of players from database are incorrect #26
• Shouldn't be possible to keep downloading user games once it reaches 100% #54
  
• $2 is a ? (mistake), not a ?? (blunder) #30

Ubuntu-only issues?

• Castling text wrap #64
  
• Missing tab closing icon #65
  
• Can't add engines #68
  • Default komodo:
    
  • Default Stockfish:
    
  • Local engines don't appear in the modal when trying to add them into the binary file input

Suggestions

• Make the size of secondary arrows depend on the evaluation #231
• Remember the sizes of window elements #146
• Make the clock progress bar animation move from right to left, just like the progress bar itself
• Keep the evaluations and lines even after the engine is stopped #103
• More keyboard shortcuts
  • New tab (Ctrl+N)
  • Load FEN or PGN from clipboard (Ctrl+Shift+V)
  • Write PGN to clipboard (Ctrl+K)
  • Analyze with all engines (Ctrl+G)
  • Stop all engines (Ctrl+H)
  • Restart engines (Ctrl+.)
  • Play vs engine (F9)
  • Engine selfplay (F11)
  • Generate game report (F12)
• Better indications for the existing keyboard shortcuts. #116
• Being able to modify and load a FEN and PGNs directly in the inputs of the info tab
• More robust FEN loading #114
  You can make some assumptions like:
  • default flags can be assumed to be w - - 0 1 if some are missing
  • if it has tabs or new lines they should be replaced with spaces
  • multiple spaces or spaces at the beginning or end should be removed
• Being able to load multiple PGNs in the import PGN game
• Delete all sidelines
• Promote line to main line #104
• Parse cutechess-style comments #142
• Different arrow colors for each engine
• More default engines (Leela, Berserk, Igel, Rubi, Koivisto, etc. Or even older Stockfish versions or Stockfish dev)
• Being able to limit what moves the engine analyzes (searchmoves)
• The engine page add new button td might need colSpan={3}

  en-croissant/src/components/engines/EnginesPage.tsx

  Lines 62 to 70 in bd3c3a7

  	<td>
  	<Button
  	onClick={() => setOpened(true)}
  	variant="default"
  	rightIcon={<IconPlus size={14} />}
  	>
  	Add new
  	</Button>
  	</td>

• Improve Play Chess options.
  • Some engines might not support Skill Level.
  • Impossible Bot should not have a Skill Level input, it should use the engine default.
  • If the user changes the default parameters, the selected bot should change to some "Custom Bot".
  • More limit customization like limit by nodes, thinking time or a time control.
  • It makes no sense to have a Color option when selecting Human.
  • The Event and player names should be filled accordingly. For example: Event: Easy Bot. Black: Stockfish 16.
• Being able to let the engine selfplay #115
• Being able to let 2 engines play against each other
• Being able to navigate the game using the scroll wheel over the chessboard #113
• Being able to disable inline notation of the moves
• Resizable chessboard
• Automatic resize of the chessboard for small screens
• Local puzzle databases #47
• Using online databases (https://github.com/noobpwnftw/chessdb) for move evaluations
• Save engine settings (fixed by Add option to save engine settings as default #92)
  It is pretty annoying having to set the settings every time I open a new tab or when closing an opening the app.
• Being able to reorder Board tabs #24
• Copy PGN to clipboard #70
• A way of running all engines at the same time
• A way of accessing the engine logs (this could be in the sidebar with "Engines" and "Report") #45
• Access to all of the engine settings #42
• Being able to limit the engine by time, nodes, mate, or no limit at all.
• Update default Komodo to 14 (https://komodochess.com/pub/komodo-14.zip)
• Eval graph
• Move tags (mistake, brilliant...) in the chessboard #78
• The promotion preview should have the same size as the board squares #43
• If the value is higher than 0 in the report, change the color so its easier to see #37
  
• The eval bar should have a (short) transition #14

These are great suggestions, thank you! I'll be working on them.

If you try to analyze a previously analyzed position, the eval and depth don't update until you get a to higher depth (even if intentional it doesn't seem like a good idea)

It was intentional, I was trying to replicate the behaviour of lichess analysis. Why do you say it's a bad idea?

Being able to load multiple PGNs in the import PGN game

That should already be the case. In the Info tab there's a dropdown to choose from the games in the file. Or do you mean loading multiple files to different tabs at the same time?

Because moving back and forth through the game can make the engine learn more about it and newer lower depths can have more accurate evaluations than older higher depths.

If you are going to keep the engine running either way, letting the user see the updated evals shouldn't be an issue. Right now it will just take more and more resources for the user to see them.

I mean pasting multiple games in the PGN game textarea and load them in the same way as the PGN file input does since right now it only loads the first game.

Wait (I haven't checked the actual code) but (in v0.5.0) the PID of the engine is changing every time a move is made so it seems like you are not using the same process (a common issue in chess interfaces that use Tauri) thus the engine doesn't actually learn from the game so what I said doesn't apply.

Therefore, you should prioritize fixing this and then eliminate the min depth issue.

App crashes trying to enable Stockfish

You used the "Save as default" feature before, right? You'll have to clear the previous saved values. I've added a button on the Help>Clear saved data for clearing all the data on localstorage.

Ah, okay, thanks

It's not possible to change the number of lines of chessdb

Do you still have this issue?

Yes, lichess works fine, but chessdb still doesn't

[franciscoBSalgueiro]

Just removing and then re-adding it should solve it.
