3chessengine's Issues

Promotions

Better Serialization (Engine Side)

See also: Board side

Prevent moat crossing if it results in check

Castling

It's possible to castle through check

TODO: Tests for checkmates

Should have many scenarios

Replace bower with yarn and webpack or parcel

@peterhurford

Creeks and Moats

Moats

• Pieces cannot cross moats unless (a) the moat is bridged and (b) moving through the moat does not capture a piece or initiate check. At no point in the game, ever, can a piece check through a moat.
• Moats surrounding a particular team become bridged if (a) that team has been eliminated or (b) that team has moved all of its outer-rank pieces (repopulating the outer-rank does not unbridge moats).
• If any knight move would carry it horizontally across a moat, then the move is illegal unless the moat is bridged.

Creeks

• Creeks prevent pawns that have not yet crossed the center from capturing across a creek.

Enforce all the moat logic

Checkmate (Engine Side)

See also: Board side

bin/update

It's possible to castle with other people's pieces?!?!

Drop moats when a side is eliminated

or when a side vacates its outer rank....

Promotions broken in production / on my local computer

I think it might be an issue with moving from git tag 0.1.9 to 0.1.10.

Pieces API lags one turn

Castling isn't prevented after the game is loaded.
