Roger Simpkins, a big, blond belter who always resembled Jack Nicklaus in every way but putting skill, found the right combination today and took a two-stroke lead at 139 in the Middle Atlantic Open.

Half the big field of 270 played at Allview and the other half at Hobbit's Glen.

Hobbit's was where Simpkins and most of the leaders, with the exception of Jim Glass, played today. Glass, unattached, who used to be an amateur out of Allview, is in a five-way tie at 141 with a group that includes Tony DeLuca of Chantilly, the low amateur thus far, and Gary Mankulish, the first day coleader.

Tom Smack, who shared the lead with Mankulish with a 67 at Allview, found the Hobbit's Glen course much tougher and shot 76 and 143. Defending champion Paul Ryan, an amateur out of Congressional, atoned for an 80 at Hobbit's Glen on Monday with a 70 at Allveiw today.

The team championship, a complicated format that took into account better ball on Monday and the sum of the 18-hole scores of the pro and his amateur partner today, went to the Chantilly pair of Glen Miller and DeLuca, 207. There are 20 golfers within five strokes of Simpkins, so it will come down to the final 18 holes Wednesday. All players will play at Hobbit's Glen.
