The LOCK Switch is a GSOH technique for switching one or multiple playing cards at the table in the action of placing the card/s back to the surface.  The move is hidden in natural movements and allows the gambler to show empty hands before and after the switch.

This serves as an introduction to LOCK SWITCHES and in this 45-minute workshop Madison teaches many variations, different handlings and approaches to the concept, with fast Lock Switches, Slow-roll Lock Switches, The OTT Lock Switch, the Lock Replacement and notes on using the Lock Switch with the Dan Macmillan Switch.
