Puzzle 188 of Thích Tình Nhã Thú is a siege built around the twin chariots. Eight of Red's nine moves are chariot checks: the pair hammer the palace in turns, and even when one chariot is captured by a black advisor mid-line the rhythm never falters; the Red pawn speaks exactly once, on move eight, before the surviving chariot finishes. Black has advisors, elephants and a chariot, cannon and horse to defend with, yet every reply is purely reactive. Prime practice for the alternating double-chariot attack and high-difficulty calculation stamina.

✓ Engine-verified — Two independent source transcriptions agree character for character; the Pikafish engine confirms Red checkmates in 9 moves.
