10...Bb4?
This places the Bishop on a
vulnerable square and leads to a loss of time. 10...Be7 is preferable
although White retains a slight edge with11.Nh4.
11.Qb3 a5
Not 11...Ba5 ? 12.Qa3 !
and Black’s position is uncomfortable.
12.Na4!
Stopping Black’s planned …Bc5
and threatening c4-c5, trapping the Bishop.
12… Be7 13.Nh4!
Now 13...Bxe2? fails to 14.Rfe1
Bh5 15.Nf5 Bf8 16.f4.
So the sacrifice of the pawn on
e2 forces the gain of the two Bishops that, thanks to the hole on b6, will
guarantee White an advantage.
13 … 0-0 14.g4 Bg6 15.Nxg6
hxg6 16.Rfd1 Rab8 17.c5 Nh7 18.Nb6! Rfd8
If 18...Nxc5? 19.Bxc5
Bxc5 20.Nd7and White wins the exchange.
19.Qc3 Bg5
20.Nc4?
Needlessly refraining from
20.Bxg5! Nxg5 21.Nxd7 (not 21.Qxa5 Ne6) 21...Rxd7 22.Rxd7 Qxd7
23.Qxe5 Qd8 24.e3, when Black has absolutely no compensation for the lost
pawn.
20...Bxe3 21.Qxe3 Re8 22.Qa3
Ra8 23.Rd2 Nhf8 24.Rad1 Red8 25.Qe3 Re8
Not 25...Ne6? 26.Nb6
Nxb6 27.cxb6 Rxd2 28.Rxd2 Qb8 29.Rd7
26.b3 Rab8 27.a3 Ra8 28.b4
axb4 29.axb4 Ra4 30.Qc3 Ra6 31.Rd6 Nf6?
This loses a pawn.
32.Nb6?
There was nothing wrong
with 32.Nxe5!
32...e4 33.e3 g5 34.Qd2 Qe7
35.Rd8 Ra3 36.Rxe8 Qxe8 37.Qb2 Ra7 38.Nc4 Qe6 39.Bf1
39.Nd6! attacking the
e4-pawn is better.
39...Nd5 40.Nb6 Nxb6 41.cxb6
At around this point the game was
adjourned. But it is not clear who sealed the move.
41… Ra4?
This terrible move seals Keres’s
fate in the tournament. The rook turns out to be vulnerable to attack
on the a4-square. It is hard to believe that Keres could have come up
with this terrible move after careful adjournment analysis. It is
possible that he sealed the move at the time of adjournment. Instead
he should have played the more solid 41…Ra8!
42.b5 Ra2
42...c5? loses a pawn after
43.Qc2 hitting c5, e4 and a4.
42...cxb5? 43.Qxb5 Ra8
(43...Ra3 44.Rd8) 44.Bg2 is also miserable for Black.
43.Qb1 cxb5?
The final blunder. But
43….c5 44.Rd8 Ra5 45.Rb8 is also a lost cause for Black.
44.Rd8 f5 45.gxf5 Qf7
46.Bxb5 g6 47.Rc8! 1-0
