The Set Up
Players set up with three handlers across the field. The four remaining players (the cutters) also line up horizontally, about 20 yards up-field from the handlers. This standard horizontal stack will become the basis for many offenses. (see Figure 1)

The Basic
A basic offense runs from a horizontal stack and relies on vertical cuts. The field is split into quarters, with each cutter having their own lane running the length of the field. Vertical cuts are made either deep or back in towards the thrower. Because each cutter has their own lane, there is little chance that cuts will interfere with one another. Players can cut in and out like pistons, and create separation from their defenders so they are open for a pass.

The only essential ingredient to running a horizontal stack is that the handler must be able to put up fast, flat, deep throws that a striker can run into. Without this option the offense breaks down because the defender can ignore the deep possibility and defend on the inside only. Similarly, if a wind is preventing a deep-strike possibility, the defense can stifle this offense by guarding inside.

One of the Commandments of ultimate is to “take what they give you.” In this case, if your defender sets up inside, fronts you and leaves a deep strike, start running deep. The same applies if the defender gives you an opportunity for an in-cut—take the 10- or 15-yard gain.

After you receive the disc, look for one of the other three cutters still jockeying in their lanes, or dump the disc back to the line of handlers which has advanced up-field behind you. As you make a catch the other cutters reset the horizontal stack 20 yards up-field. If the handlers don’t see an open cut up-field they simply swing the disc over to one of the other three handlers to reset the stall count.

Defending against a vertical cut is difficult as both the deep strike and the in-cut are possible. A simple strategy when your cutter is faster than you is to shift behind your mark so he or she can’t take the deep strike, and hope you get a play at the disc inside. If you’re faster than your cutter you do the reverse, with the intent that the cutter can be caught in a race to the huck.

Also, if the person with the disc doesn’t have an effective deep throw (such as a cutter who has received a pass) it is only necessary to cover the in-cut until a handler has the disc again. This should curb the offensive team’s up-field flow.

When defending a disc on one side of the field, you can poach off the cutter on the opposite side of the field to interfere with the open space. This can work if you do it sparingly, but if you’re predictable your cutters will react as they would with any poach—by getting to open space where they can call for the disc and burn you.

Advanced Ideas

With the basic set running smoothly, some further ideas can improve effectiveness.

Often two cutters on the same side of the field will cut in or out at the same time, which fails to open space for a pass. To alleviate this, pair up and communicate so that one goes in while the other goes out. This opens up space and you can adjust your in-cut across two lane widths to get open. If you use the extra lane-width and don’t get the disc, it is important to reset after a cut so that your cutting partner still has a lane to use. In much the same way, defenders on one side of the field will pair up, one covering the deep threat and one covering the in-cut.
In this case, a double in-cut (both cutters coming in on the same side) will split the single defender and one of you will be open.

This vertical cut may be all a team needs to run a smooth offense, and it’s what you should run until you’re familiar with it. Eventually however, you will run into a team that knows how to defend this basic horizontal stack offense.

The Next Level

When confronted with such an experienced and cagey defense, the horizontal stack becomes the starting point for horizontal cuts. This offense can be run as a set-play with each person knowing where and when they are going to cut, or it can be the start of a free-flow offense with everyone reacting to the open space.

To initiate a set-play offense, one person (you) is chosen to start a horizontal cut. Cut across the field inside the defenders to open up more space for the remaining cutter on the same side. The disc may go to you if you’re open, but more often will go to the following cut, which should be wide open.

At this point the disc and all four cutters are compacted into a short stack on one side of the field, leaving much open field space to work with. The next cut could be another horizontal cut into the now-open side from the other pair of cutters, or a deep angle cut to the empty side, or it could include both. (see Figure 3)

With the disc moved this close to the goal line, a team can now set up one of their end-zone plays to finish off the point.

Alternatively, the play can become a free-flowing offense. Using the horizontal stack this way requires good field-space recognition as there are no longer individual lanes and it’s possible to clog the flow. You need to see what other cutters are doing and react to the space they are creating. If you make a horizontal cut, there will be a hole left where you started that another cutter can use. If you cut away from your partner, there will be more room for him or her. If you make a cut and don’t get the disc, you must reset into the horizontal stack. Sometimes when you’re in the stack you have to shift over a lane to make space and reset to the position closest to where you finished your last cut. Once again, recognize what other cutters are doing, find the open space, and use what the defense gives you.

A major benefit of the horizontal stack is that these two completely opposite offenses, the basic vertical cuts and the next level of horizontal cuts, are run from the same starting position. To take full advantage of these offenses, you must recognize the space that the defense leaves you and choose your offense accordingly. Pre-set audible calls to indicate which offense will be played. As you pick up the disc, make a choice and call it out. The defense won’t know what’s happening until the first cut is initiated, too late to adjust their field positioning.

These ideas are only a starting point for formulating an offense off of the horizontal stack. There are numerous variations, which you will see run by the best teams. Keep an eye on the offense in the final of the next big tourney and you’ll recognize a horizontal stack, and perhaps notice some aspects you can use for your own team strategy.
