{Louis D. Statham (1907-1983) invented medical instruments and became rich. He
sold his house in LA to Hugh Hefner. It became the Playboy Mansion. Statham
moved to Lone Pine, a village in the desert of California. He sponsored the
Lone Pine Open from 1971 until 1981. Fischer's successes were a great stimulus.
Kashdan became the director. 33 players with a US rating of 2000+ carried out
seven Swiss rounds from 14 until 20 iii 1971 during the first installment.  
The contemplation times were two-and-a-half hours for 40 moves during the
afternoon and one hour for 16 moves during the evening.   Evans had spoiled a
drawn position in the first round.} 48. Ka3 (48. Kc2 Qc3+ 49. Kd1 Qa1+ 50. Ke2
