实招 is the contracted form of
如实招供 ('confess truthfully'). Most often heard in interrogation or accusation contexts:
从实招来! ('come clean!'). The
招 here means 'to confess' (as in
招供); separately,
招 can also mean 'a move/tactic', so
实招 occasionally means 'a real, effective move' in the context of strategy or martial arts.
