8.Be3The Bishop is here in a somewhat exposed position; nor was its development yet in any way pressing. 8) R - K sq, B - B sq; 9) B - B sq appears to be a good plan, in order to secure the centre Pawns and guard the Bishops against exchanges.
10…c6After 10) ..., P x P; 11) B x P, Kt x K P?; 12) B - Q 3 Black would have a lost position.
13…Nf8The cramped White pieces have no object of attack.
14.c5Bringing about interesting complications, and giving an opening to the cramped heap of White pieces; but there is no gain in the transaction.
25.Nf6+More natural was 25) B - B 4, in order to continue, after 25) ..., Kt - B 4, with 26) K R - K sq.
27.Rd7A gross blunder, which costs the K B P.
43…b5At last he has succeeded in forcing the important advance of the doubled Pawn.
