29. Qb6 $2 (29. Kd2 {with a favourable setup compared to the game, maintains
White's advantage}) 29... Ra5 $1 {using a simple tactic to get the rook in
behind the White forces} 30. Kd2 (30. Qxa5 $4 b2 {of course, wins for Black})
30... Ra1 (30... Ra2 $1 {Black needs to hassle the king, with the constant
threat of advancing the b-pawn. There is no good way for White to escape this,
as these sample lines show:} 31. Kc1 Ra1+ 32. Kb2 (32. Kd2 Ra2 {repeats}) 32...
Ra2+ 33. Kc1 (33. Kc3 $4 Bd1 34. e4 Rc2+ 35. Kxb3 (35. Kd3 Be2+ 36. Ke3 Bc4 {
and the pawn advances next}) 35... Rc6+ {wins for Black}) 33... Ra1+ 34. Kd2
Ra2 35. Kc1 {with a draw by repetition}) 31. Kc3 Rf1 $2 (31... Rc1 {hassling
the king from another direction, would again be enough to draw}) 32. Qb8+ Kh7
33. Qf4 $1 {I had "blundered" this re-routing of the queen to f4. Now White is
pressing once again.} Kg8 $6 {At this point I was running very short of time
leading up to the move 40 time-control, and didnt manage to come up with a
better defence than protecting my pawns} (33... Rd1 $1 {was more to the point}
34. Qxf7 (34. h4 f6 35. g4 {gives White some chances, but is much better than
the game for Black}) 34... Rd3+ 35. Kb2 Rd2 {and despite losing the f7-pawn,
Black has the "king hassle" setup again}) 34. e4 Rd1 35. Qe3 Kf8 36. f3 Kg8 37.
h4 Kf8 38. g4 f6 $6 {This gives White more targets on the kingside} 39. Qf4
Rd3+ 40. Kb2 Kg8 41. d5 {The first move after the time control at move 40.
Dlugy spent quite some time in thought here - he has a choice of good
continuations. 41 d5 is not a bad move in itself but it was based on the
concept that White followed in the game. He had seen the position where both
sides queen their pawns, but missed the perpetual that occured in the game.
Both} (41. g5 {and}) (41. e5 {give White excellent winning chances}) 41... e5
42. Qf5 Rd2 43. Qc8+ Kh7 44. Qc3 Rd3 45. Qc7 $6 (45. Qc4 {is better, keeping a
close eye on the rook, and then} Rd2 {or} (45... Rxf3 46. Qe2 Rd3 47. g5 $1)
46. Qb4 Rd3 47. g5 {returning to the idea of creating a second weakness on the
kingside. White is winning.}) 45... Rd2 46. d6 $2 {Now there is no turning back

48. Kb1 $2 Be2 $19 {and ...Bd3 wins.}) 48... b1=Q 49. d7 Ba4 {Only move.} 50. d8=Q Qd1+
{Only move.} 51. Ke3 Qe1+ {Only move.} 52. Kd3 Bb5+ {Only move.} {Nice geometry, White's king is stuck in a
'box' and White's two queens can only stand and watch} 53. Kc2 Ba4+ 54. Kb2
Qb4+ {Only move.} 55. Ka1 Qa3+ {Only move.} 56. Kb1 Qb4+ {It was not too late to go wrong, the
(for some reason) more natural} (56... Qb3+ $4 {allows the king to escape} 57.
