The 2 Board Press is one of the top 5 all-time max effort exercises. This is because the 2 Board places the bar in the sticking point for many lifters (approx. 4 inches off of the chest.)
To perform the 2 Board, all you need is a 2 Board Press (this is 2 2x6 boards) placed on the chest. Bring the bar into the boards, but don't heave the bar off of the boards. You need to let the bar sink into the boards, but don't use that momentum to cheat your weights up.
Make sure you use the same form as your regular bench.
You can use a close, medium or wide grip on this lift. This is most commonly used as a max effort exercise and thus working up to a 1-3RM is most often done. However, you can use this as a supplemental lift and work for multiple sets of 3-8 reps.
