The front cover shows tlree new two-pi.ece records. The other nro-piece records, whictt still stand, are: KQ = KR = 40, QB =Qg = 30. QR = 16, RS = 64, BS = 112. Of the original three and four piece tasks only my QRB = 36 rezult survives the on- slaughtof"mesrsDuceandYlikarjula. MrDrice'iresultswerecirculatedinoneof his last communications to: the Fairy Ches Correspondence Circte before it closed in L982. M Ylikarjula's elmpreherisive results wdre sent to me on 29 December L982, some of his results equiUeA those of Mr Duce but the/record must stay witli W. H. D. Similarly Mr A. Willmott sent a result on 27 May-suggests 1983 whidt equalled the KB S record bi S. Y. with an identical position, which that 504 must probably be ttre ultimate atrainable in this case. But I still suspect that furttrer idvanc6ment of some of the records can be achieved.
