The largest intercollegiate bridge event of 1968, the Eastern Intercollegiate, will be held at the M.I.T. Student Union to day and Sunday. The Harvard Undergraduate Bridge Club will sponsor an Open Pairs Championship at 2 p.m. and 8 p.m. today, and an Open Teams at 1 p.m. and 7 p.m. on Sunday.

The tournament is open to any full time student, and ACBL membership is not required. Fine teams from Texas, Maryland, Toronto, and Columbia will be returning to participate this year.

Last November the contingent successfully defended its unblemished record in intercollegiate competition by defeating a strong Columbia team at the Brandeis Invitational Knockout Tournament. The members of that squad playing together for the last time are: Don Bloch, Peter Y. Connor, Lawrence A. Darby, Emmett Keeler, John V. Lindsey II, and Mark Thompson.
