vonKrolock: <6.d4> According to Suetin, Boleslawski was very fond of this variation - sharper then that of Smyslov vs Flohr, 1950 or Aronin vs Flohr, 1950 from the same Tournament - and he liked to sacrifice some Pawns while playing this - Really a fine psichological coup to transform a Caro-Khan in a Gambit...
<8...Qd4> alea jacta est
<9...Qd8> Evidently to capture the second Pawn would be very risky
<12...Qb6> Going the wrong path - 12...Qa4 13.Nf6 Nf6 14.Bb3 Qe4 15.Qg3 0-0-0 was what Boles expected from his powerfull oponent
<13...Ne4?> "Already the decisive mistake" (Suetin)
<14...Nf6> "Or 14...Nc5 15.Re2 Be7 16.Bc3 0-0 17.Qg3 g6 18. Qe5 whith a wining position" (ditto)
<15.Be6!> A nice stroke
<16...Be7> Or 16...Kf7 17.Rf6! gf 18.Qh5 Kg8 (best) 19.Qg4 Kf7 20.Qc4 Kg7 21.Be3 Qb4 22.Rd7 Kg6 23.Qf7 Kf5 24.c3! Qb5 25.g4 Ke4 26.Qf6 (Boleslawski)
<17...Nd5> Or 17...0-0 18.Re7 Nd5 19.Rg7!! Kg7 20.Bc3 Nc3 21.Re7 Kh6 22.Qc3 etc
<23.b3> Not 23.Rb7?? Ka8 and the double therat Qe1 or d2 decides... for Black!
The rest is silence (a matter of technic for White's victory)
