thomastonk: <whiteshark> You write about a <7.. g6 > line in those days, but I could find only one more game with this position played by the same players and three games played 1966 and later. So I would very much appreciate a source or further information.
Maybe you are interested in my view of the game. After 17.Rh7 the main theme of the game is this dominating rook. White has thereby a slight, but enduring edge. 17.. b5 is a minor mistake, because it increases the rook's effect; 20.. Kb7 is a serious mistake, loosing two moves.
23.a3 is a double-edged move, because it weakens b3 seriously, and makes White's queen's side pawns immobile, but I don't see a prophylactic effect. 23.g4 would have been a fine example of restriction.
23.. Nf5 is another serious mistake, and now White should be winning. The reply 24.g4 is quite naturally here, but 24.Nb4 is a pretty alternative, inceasing the rook's power.
25.Ncd4 is a blockade, but a self-blockade! 25.Qe3 and 25.Ng5 are much better. Beginning with this mistake, Paulsen looses almost all of his advantage until move 32, and - though I generally like his play very much - I have to say, that he is playing badly here. Imagine Black would have played 32.. Nb3 -- yes, this little square that has been weakened in move 23rd! Suddenly, d4 becomes a threat. After, say 33.Qf4, Black has 33.. a5 with the new threat of b4. White still has this rook on h7, but Black is closer to equality than White to winning, I believe.
