4.e3
A quiet favorite with which I have lost just 3x in 16 tries (now 10-3-3).

4...g6
[For 4...d5
see my 2005 STCWC win vs. KillerQueen.; For 4...d6
; & 4...e6
see my respective losses to Chieu (Springfield Swiss #2, 2003) & Kernighan (2008 KCCC).
On 2nd thought, don't look at the latter; I lost in 18 moves!!]

5.a3!?
[The idea behind this waiting move is 5...d5 6.cxd5 Nxd5 & a better development for the Bf1; which could go to c4 or b5.
I've also played 5.Be2
(2x); & 5.d4
here.]

[10.h3
, preventing the following, was good too but we'll let Black yield the B pair, if he so desires.]

11.Be3

I expect my foe to play against c4.

12.Rc1
[This takes the R out of the Bg7's range & defends c3 in case I want or need to play b3. But >=12.h3
Bxf3
13.Bxf3+/=
]

12...a6
[This safeguards his a-pawn ahead of ...Rc8 (& also prepares ...Qc7) but weakens the b6 square and was apparently unnecessary as 12...Rc8!

but after 18...Ned7

19.fxe5

Exactly was I was looking for. Now let's go back to the long diagonal & see how Black responds.

27...Ng5?
[This lets me steal the b7 P. 27...Nf6+/=
over-protecting the Re8 & tactically defending the endangered b7 against 28.Bxb7?
(28... 28...Rb8
29.Bc6

) was indicated.
Now, I can steal the b7P beause the Re8 & N will hang.]

35...Nd3??
[This works out but only because I blunder. >=35...Nd7+/-
]

36.Bd6??
[This throws a half-point away & ultimately costs me $25 (A victory here would've tied for 1st). 36.Ba7
Rxc2
37.Bxc2

would've won. Now White runs into an overload & fork.]

41.Bb4=
Drawn by agreement...
... because all the Ps are on one side of the board.
But, with a 3 minute lead, Ilya could have played on in the hope that I would make more mistakes in time-pressure.
Time left - Moldovan 2:36, I. Zhurbinsky 5:36
Estimated time used - Moldovan 42:24, I. Zhurbinsky 39:24
