Art Chaos: MS Bitburg 2012

Red circles indicate a primary position taken more than 60% of the time OTB. In the case of Home & the D-side Can it ranged between 80-100% of the time. And the orange circled TCK on the D-side developed over the weekend into a near constant primary OTB. Otherwise orange colored props were alternative primaries used at least 25% of the time. The two that are also green indicate the principle secondary props. The light blue SD was an unusual primary OTB as was the snake corner CK; they were used primarily to break their previous patterns and get wide guns up asap.
From the color coding it's easy to see that the basic Art Chaos (AC) strategy OTB is to minimize early risk and get guns up quickly for lane control. What is less obvious is that AC consistently played the D-wire as the strong side of the field--by that I mean they tended to commit their 3rd gun to that side even when the intent was to go up the middle. They also preferred the majority of the time to fill the upfield middle props via secondary rotations once they could make a decision about where to commit their guns after either getting an elimination or gaining clear control over a portion of the field with their guns.
Here's the basic breakout: red T, 2 guns at Home, the D-side insert Can plus either upfield TCK or Can or the D-side TCK. The most common choices were the D-side TCK and the upfield Can. In purple you can see the primary lanes shot OTB (with some minor variations). The plan is simple enough; keep 5 bodies alive OTB and play early contain. The red T played wide can control rotations to the corner or snake and if played on the inside can counter secondary moves up the middle. Both sides of Home shoot constant lanes either keeping the opponent inside or forcing them to move thru the lanes risking elimination. With two shooters at Home there are players in reserve who can move either direction to fill for eliminated teammates or take up secondary positions that begin to lock the field down. For that purpose the preferred route was the upfield D-side Can. The snake shaded TCK was used less often and frequently earlier, as an aggressive secondary move, to increase the pressure on the opponents in their primaries for eliminations and as a change of pace. The principle attack was a direct line to the D-side of the M followed immediately--or as nearly as possible--with a sweep up thru the doritos. (Occasionally vice versa) Snake side play looked to bump wide to the wire and if a snake option presented itself--due to previous eliminations mostly--a closing sweep along the snake wire could be incorporated in the close out.
There were some tactical options that largely amounted to adjusting the timing of certain actions in order to alter shooting lanes either OTB or in expectation of countering an expected move, etc. In any event the basic game plan is as described. If any AC matches become available to watch, particularly prelim matches, you will plainly see the core pattern and follow-up execution outlined here.
