In an article in the 1969 bulletin of the Latvian Chess Club, Boles-lavsky suggested 22 Q-R5 but it would appear that Black has at least two good lines against this try:
a) 22 ... K-B2 23 N-K7 R-Kl 24 Q x BP B-R3 + 25 K-Nl KR-B1 and 26 ... RxP+ + ;
b) 22 ... P-R4 23 R-K3 K-B2 24 R/l-Kl K-N3 25 K-Nl R-KN1 26 Q x RP R-N3 27 Q-R4 Q-N5 28 QxQ RxQ, and with the exchange of queens Black has consolidated his material advantage. Gurevich-Shershnev, ¿-final Latvian Corres Ch 1969-70.
