lichess-bot's Issues

Capture Lichess error message

Sometimes Lichess produces HTTP 400, although the second example refers to an unfinished game where Lichess rejected a legal move. It would be good to output the error message produced by Lichess:

Reconnect after Lichess restart

Similar to lichess-bot-devs/lichess-bot#584 , automatically reconnect the client if Lichess restarts.

Log?

I attempted to play a chess960 game against my bot (Stockfish supports every Lichess variant), and I don't know what went wrong:
https://lichess.org/Bg5bUFlW

Do not decline challenge after accepting it

Apparently if an opponent's lag or online status changes, there are two challenge events. This wrapper doesn't care about the opponent's lag or online status.

Perhaps the first step of this function should be to check whether lichess-bot thinks it has a game in progress whose ID is the same as the challenge ID:

lichess-bot/stream_event.go

Lines 64 to 73 in 97af669

    
           func handleEvent(e *event, eng *uci.Engine) { 
        
           	switch e.Type { 
        
           	case "challenge": 
        
           		if validChallenge(&e.Challenge) && !gameInProgress() { 
        
           			log.Println("Accepting challenge", e.Challenge) 
        
           			acceptChallenge(e.Challenge.Id) 
        
           		} else { 
        
           			log.Println("Declining challenge", e.Challenge) 
        
           			declineChallenge(e.Challenge.Id) 
        
           		}

Lichess now supports specifying a reason for declining a challenge #247

There's a new field in the API: https://lichess.org/api#operation/challengeDecline

Maybe lichess-bot could make use of it.

Copied from lichess-bot-devs/lichess-bot#247

Feature request: abort against sleeping opponent

BOT opponents might take more than an hour on their first move:
https://lichess.org/wCezm8ck/black

Rather than leaving the game hanging forever, maybe after an hour abort the game.
