  Chessical: A very rapid and impressive positional crush by Polugaevsky of a strong player's Semi-Slav Defense.

Biyiasas resigns as he has no answer to the threat of <d6>, e.g.27.Bxc4 Qd6 28.Bxe5 Qxe5 29.d6+

Biyiasas seemed uncomfortable as Black in the Meran which does not appear to have been a main line defence for him. The manoeuvre <Re7> and <Ne8> seems unnatural, and I think it would have been a good idea to instead play <a5>.

Did Biyiasas choose this defence as Polugaevsky had little experience with it, unlike the Kings's Indian which was a first string Queen's pawn defence for Biyiasas?

It is obvious that Polugaevsky understood the opening very well anyway, perhaps he remembered G Ilivitsky vs Polugaevsky, 1953.

Jan-17-15  Everett: Can Black improve with something else on move 15? He destroys his own q-side play and gives up c4 for nothing. How about 15..c4!?, releasing c5 for a black piece, freeing the a7-g1 diagonal for bishop or queen, and even consider exchanging on c3 after ...Bb4.

In any case, Black after <15..c4 16.bxc4 b4 with a classic blockade square on c5 available looks much better than the game.

  perfidious: <Everett> That is a standard idea for Black in the Reynolds--do not recall whether I this exact position way back when, often as I played 10.d5 in the 1980s, though.
Jan-17-15  jvv: 15..c4 16.axb5! axb5 17. bxc4 b4 18.Kb5.
That's the idea behind 14.Bf1.
Jan-18-15  Everett: <Jan-17-15 jvv: 15..c4 16.axb5! axb5 17. bxc4 b4 18.Kb5. That's the idea behind 14.Bf1.>

I don't think that changes much regarding Black's compensation on the dark squares and c5 in particular. He gains a passer, pressure on e4, and squares for his pieces.

<..c4 16.axb5 axb5 17. bxc4 b4 18.Nb5 Nc5> and Black has more play than in the game. Both players can go wrong here, as opposed to one way traffic for White.
