In Game #2 of Truth and Lies, there were actually 6 truths, not 3.
From now on, every puzzle will be internally verified before I send it. There will be exactly the announced number of truths or lies.
- ✅ True. In Chess960, after castling, the king and rook end up on the same destination squares as in standard chess (king on g/c, rook on f/d).
- ✅ True. A pawn can absolutely deliver checkmate.
- ❌ False. Threefold repetition is not automatic. A player must claim the draw (under standard FIDE rules).
- ✅ True. Fool's Mate ends on White's second move.
- ✅ True. Two bishops (one on each color, since they start on opposite colors) can force checkmate against a lone king.
- ✅ True. King vs. king is an immediate draw due to insufficient mating material.
- ❌ False. A knight attacks 8 squares only from the center. On edges and corners it attacks fewer.
- ✅ True. In principle, all eight pawns can promote, and they can all be promoted to knights if the game permits.
