How does the split power play work?

The base mechanic is one gesture: as soon as the puck reaches one defenseman, it goes straight to the other. That relay forces the penalty kill to cover the full width of the blue line instead of camping on one side. Both defensemen must be ready to shoot, and a wrist shot is perfectly acceptable when time and space are short.

The two half-boards players work exactly as in the 1-3-1: right shot on the left, left shot on the right, with the priority of moving the puck up to the defensemen, especially when the pressure comes from below, rather than forcing a play through the box. The net man keeps the same mandate as everywhere else: stay active, get into shooting lanes, release to one side for a low pass, and relay the puck behind the net to the opposite half-wall to escape pressure.

Five options are taught. The D-to-D point shot, with instructions to aim low because a low shot leaves a rebound the goalie handles badly. The D-to-D and back, where the second defenseman's fake opens the shooting angle for the first, right in the middle. The D-to-D cross-seam pass to a half-boards player for a one-timer. The double-seam pass, which adds a second fake and crosses the ice twice. And the low-release play, a chain of three fakes ending with a low feed to the net man and a choice between driving the net and the back door.

The strength of the split matches that of the 1-3-1: it is hard for an aggressive kill to defend, because every pressure release leaves a lane. It also has an advantage of its own: it converts easily into an overload and back mid-shift, with no personnel change. And when the defensemen shoot, lanes open mechanically for the forwards below them.

Its weakness is sequence length. The low release demands three consecutive fakes, and rushing the chain makes it readable from the first pass. A strict zone kill that reacts to no individual fake absorbs the whole sequence without moving. A killer glued to the cross-seam receiver from the first fake kills the one-timer. And a goalie who controls his low rebounds removes most of the benefit of option 1.

One look at the blue line is enough: two defensemen lined up and nobody planted in the slot means a split. Count the D-to-D relays that actually end in a shot, and watch where the rebounds go. With RinkLog shots are located and timestamped, which lets you check whether rebounds really went to the sides, the way the system intends.
