1.d4 d5 2.Nf3 Nf6 3.e3 e6 4.Nbd2 c5 5.c3
The Colle Opening named after the Belgian player Edgard Colle (1897-1932) who only a few years before the present game produced a string of brilliant wins with this opening.

5...Nc6
Black may also play Nbd7 in conjuntion with Be7, as in the main game, or play instead Bd6.

6.Bd3 Be7
[Another variation is 6...Bd6 7.0-0 0-0 but if White plays now 8.dxc5 Bxc5 makes whether Be7 or Bd6 has been played irrelevant. Now White may play in the centre with 9.e4 (or produce a position which is a Meran variation of the Semi-Slav with an extra tempo by 9.b4 Bd6 10.Bb2 ) 9...Qc7 10.Qe2 ]

7.0-0 0-0 8.Re1
[8.Qe2 is another way of aiming for e4, or possibly transposing to the earlier note with dxc5.]

8...Bd7
Straightforward development of a piece which is actually a relatively rare, but playable, move in this position. Black more often fianchettoes this bishop via 8...b6, or keeps matters fluid with the queen move Qc7.

9.e4
This this is a typical move in the Colle, which can lead to a strong attack and even Bxh7+ sacrifices, in particular if White is allowed to play e5. However, here its a little early, and Black obtains a comfortable opening with the following interesting scheme.

9...dxe4 10.Nxe4 cxd4 11.cxd4 Nb4 12.Bb1
Quite a typical idea in this opening retaining the potentially powerful attacking bishop even though the queens rook is shut in for some moves. Objectively though the opening has not gone that well for White so better was an effort to stabilise the game with [12.Ne5 despite allowing Black to exchange the sometimes explosive Bd3 hence much of the attacking potential of the Colle is lost.]

12...Nxe4 13.Rxe4 Bc6 14.Rg4
White seemed determined to try and attain an attacking formation with this very aggressive move. Black in turn stays calm and defends accurately over the next several moves utilising the pressure on the weak d4 pawn, and the fact the White rook is slighlty misplaced to restrain White's attack. [So 14.Re3 seems sounder, guarding the Nf3, even though Black can securely safeguard his position with 14...Bf6 15.Ne5 g6 ]

14...Bf6
Very solid defending g7 and applying pressure on d4. Another good line was the immediate [14...Bxf3 although play gets somewhat messy after 15.Qxf3 (or 15.gxf3 f5 16.Rg3 Nd5 17.Bh6 Bf6 and Black has a large positional advantage.) 15...f5 embarrassing the rook 16.a3 (if 16.Rg3 simply 16...Qxd4 ) 16...fxg4 17.Qe4 g6 18.axb4 ]

15.Bh6 Re8
Sidesteppng the pin so later White will need to worry about the possibility of gxh6.

16.Qd2?
Attacking b4 with tempo and generating ideas such as Qxh6 if Black manges to play gxh6. The move misjudges the strength of Black's reply and White doesn't get any significant chances on the newly opened g-file. [White avoided the more natural attacking move 16.Ng5 possibly due to the exchange 16...Bxg5! when play may continue (In contrast to the variation given earlier 16...g6 now is a little risky due to White being able to continue to build up an attack with 17.h4 (or even the sacrificial 17.Nxh7! Kxh7 and now another bombshell seems good enough for at least a level game 18.Rxg6! fxg6 19.Qh5 Qe7 (19...Qd7 20.Qxg6+ Kh8 21.Qxf6+ Kg8 and White can bring the queen's rook into play with the devestating move 22.a4 followed by Ra3 and swining the rook to the kings-side.) 20.Qxg6+ (Not 20.Bxg6+ which loses to the retreat 20...Kg8 ending White's attack.) 20...Kh8 21.Qh5 Rad8 (or 21...Kg8 when 22.Qg6+ Kh8 23.Qh5 repeats.) 22.Bf8+ Kg8 23.Bxe7 Rxe7 with about equal material and chances for both players.) ) 17.Rxg5 g6 18.Qd2 Nd5 when Black's position is rock solid and he can then contemplate completion of development with Qb6 and Rad8 or c8 starting to pressure White.]

16...Bxf3 17.gxf3 Nd5
A nice square for the knight, securely blockading the IQP on d4, and keeping in touch with the kings-side should further reinforcements be needed in that area of the board.

18.h4 Ne7
Again very solid, giving the option of Nf5 pushing White back, and once again reinforcing the key g7 pawn.

19.h5 Kh8
Another nicely timed move. Instead [19...Nf5 is not so clear after 20.Bxg7 Nxg7 (worst is 20...Bxg7 21.h6 Kh8 22.hxg7+ Kg8 (22...Nxg7 23.Qh6 and mates.) 23.d5 and White seems fine.) 21.h6 Kh8 22.hxg7+ Bxg7 and White can jettison a pawn to obtain bishops of opposite colour in an ending via 23.d5 Qxd5 24.Qxd5 exd5 25.Bd3 ]

20.Bg5 Nf5 21.d5
Attempting to confuse the issue but no better is [21.Bxf5 exf5 22.Bxf6 (22.Rg3 Qxd4 ) 22...Qxf6 23.Rg3 Rad8-/+ ]

21...Bxg5 22.Rxg5?
In continuing to attack White finally errs decisively. Queens had to be exchanged with [22.Qxg5 Qxg5 23.Rxg5 Nd4 24.Kg2 despite Black having a far superior ending after 24...Rad8 due to better development and pawn structure.]

22...Nd4
Now Black is wining since White's pieces are becoming uncoordinated and the attack has vanished.

23.Be4
[23.Kg2 offered little hope as Black can eventually win the d5 pawn. For instance, after 23...e5 24.Be4 Rc8 25.Rg1 f6 26.Rg3 f5 ]

23...f5 24.f4 Qf6
[Note that 24...fxe4 is poor due to 25.Qxd4 and White has equalised.]

25.Rd1 e5 26.fxe5 Rxe5 27.Bg2
[Unfortunately for White if the rook retreats by 27.Rg3 then 27...Rxe4 just wins outright.]

27...Rae8!?
Another very solid move bringing the last piece into play. [Even stronger was 27...Re2! for instance if now 28.Qf4 Black has the very neat 28...Re4 29.Bxe4 Ne2+ ]

28.f4?
[28.Kh1 gives some hope of survival even though Black is much better after 28...Ne2 ]

28...Ne2+
Black now wavers a little, possibly due to time trouble, but does manage to clear up in the end.

29.Kh2 h6
The right idea but not quite at the right moment. [Instead 29...Re3 30.Qc2 h6 31.Rxf5 (31.Qxf5 hxg5 ) 31...Qh4+ mates.]

30.fxe5 Qxe5+ 31.Kh1 hxg5 32.Qxg5 Ng3+ 33.Kg1 Qe2 34.Rd2?
A final error which loses simply. The retreat [34.Qd2 holds on for a whilst after 34...Qxh5 35.Re1 and White is still kicking but a clear pawn down (Note the obvious 35.d6 allows Black a crushing attack by 35...Ne2+ 36.Kf2 Qh4+ 37.Kf1 Qh2-+ ) ]

34...Qe1+
[Following 34...Qe1+ 35.Kh2 then 35...Ne4 is a knock-out move. This was Prins only loss in this event which he won by a clear margin of 1.5 points. P.M.List (Lithuania), and remarkably H.E.Price finished equal second. This required a finishing burst of 5.5/6 from the latter as he lost his opening 3 games!] 0-1
