Chris Ohiri may be back in action this afternoon at 2 p.m. when the varsity soccer team faces Dartmouth on the Business School Field-and then again, he may not. Doctors will decide this morning. But it is reasonably certain that whether the Crimson's star center forward plays or not, there will be no recurrence of the paralysis that struck the team against Williams.

Coach Bruce Munro said last night that one reason for the Crimson's 3-2 upset loss to Williams was that "we didn't know that Chris wasn't going to play until a couple of days before the game." The team had little opportunity to work on a new, Ohiri-less offense before the Williams contest.

"The team learned most of what it know about the new offense on a blackboard before the game," Munro said. As a result, the varsity played a weak, tentative brand of soccer.

Munro claimed, "Now they know the offense." The varsity showed more than a passing acquaintance with the new attack in defeating Columbia, 4 to 0 last Saturday.

In the first few games of the season, when Ohiri was healthy, the team concentrated on setting him up for shots at the goal. This strategy gave the Nigerian Olympian 14 goals in his first three games.

Without Ohiri, the Crimson passes to the wings more often, and relies on them to carry the ball downfield. And the wings and insides are expected to shoot, a purely incidental function when Ohiri is in the game. With this system in effect, Seamus Malin, Eb Klufio, John Thorndike, and Al Chang accounted for the varsity's scoring against Columbia.

Dartmouth stands seventh in the Ivy soccer race, with an 1-2-0 record. (The Crimson's 2-0-0 mark puts it in first place.) But the Indians can be rough; a week ago, they battled Princeton through two overtimes before bowing, 1 to 0. Last fall, Dartmouth treated the varsity to one of the low points in the long history of Harvard soccer, winning 5 to 3 in what Munro called "a comedy of errors."

The Indians like to use a "four-full-back" defense, with one man playing fairly close to the goalie and three more lined up father out, Dartmouth goalie Duke Ellington is a good one. On offense, wing Keith Streuli has been a standout.

Crimson fullback Lou Williams will be out with a pulled knee muscle, and Sandy Cortesi will start in his place. Inside and captain Ted Wendell is still not at full speed, but halfback Tony Davies and Thorndike, an inside, have recovered from minor injuries.
