How to Beat Kingside Karl
- Kingside Karl loves to attack — make sure your king is safely castled before the middlegame begins.
- Defend carefully against early sacrifices. Take the material and consolidate; aggressive bots often run out of steam if you survive the storm.
- Trade queens when you can — without their attacking piece, aggressive bots lose their main weapon.
- Avoid weakening your kingside pawn structure; they will be the target of attack.
