school CC player. I began playing back in the 1990s when it was called
“postal” chess and we were mailing postcards around the world. As a
carryover from those days, I often exchange text messages with all my
opponents while transmitting my moves.   During my pre-tournament research and
preparation, I wanted to avoid drawish variations. I knew that wins would be
at an extreme premium in the 21st Olympiad because 95% of high-level
international games end in a draw. With White, I therefore tailored a mixture
of 1.d4, 1.e4, and 1.Nf3 openings to my specific opponents. Like all the other
Olympiad competitors, I used Stockfish 11 and 12 (released September 20, 2020)

general idea was to keep maneuvering and repositioning my pieces. My theory at
the time was that most chess engines do not excel in very closed and highly
positional games. Therefore, I wanted a very positional battle with few
exchanges, hoping to reduce the tactical impact of chess engines, and also
because Black will have less space.  One other note as we proceed: it is
well-known that Stockfish hates the King's Indian Defense for Black. So, I had
to guard against being lulled into a false sense of security owing to SF’s
constantly rosy evaluation of White’s position.} Rb8 16. h3 a6 17. Rc2 Bd7

engine evaluation with the NNUE networks become stark. Both SF11 and 12 think
White is better, but 11 shuffles the pieces around in its variations, while 12
likes this break immensely! At the time, however, I found 11's suggestions to
be of no help, and I was also concerned that Dima might be using Leela Chess

pawns, but the rook now has a half-open file and can put pressure on the
a7-pawn. One should also be thinking about using the doubled pawns to weaken
the queen side more via b3-b4-b5x6 and then b2-b4 etc.} Be7 10. h3 Na6 11. g4 {
Claiming space on the kingside too. Black's pieces will be pushed back, and

Now it's clear that 11...Nb4 (as in Bokar-Novak, ICCF 2020) should haven been
played earlier. The pawns are moving forward per our plan. In over-the-board
play, one might be worried about the rook getting trapped, but this is where
correspondence chess has its advantages. We can see that White will exchange
his rook for the knight and keep dominance over the dark squares.} Bc2 15. Rxa6

Stockfish 12 evaluates this at +2.5 or so, while the latest development
versions of SF are more sanguine, thinking that White is around +1.3, showing
that it may not be easy to break through. It's important to have a plan in
closed positions; here, I have the bishops and space, and the bishops gain in
power with more space. So my plan is to push e3-e4 and target the c6-pawn.} Nf8

35. Ne3 Bg7 36. Ra1 Rb7 37. Rh1 Bf8 {[#] The computer hasn't changed its
evaluation in several moves, and it does seem that White is shifting around
without progress. Is everything protected? Let's take stock: the a7- and
c6-pawns are weak and need at least the rook to protect both. The f6-pawn is
also weak, and the rook can try to target it. Which piece in White's army
isn't doing much? The knight! We need to get it to h5, d6, or f5. My opponent
must have thought he was safe despite the computer evaluation, and it does
seem like White will struggle to make progress.} 38. Nf1 Nxf5 39. gxf5 Re7 40.
Ng3 Bg7 41. Kd3 Bf8 42. Ra1 Bh6 43. Ra6 Rc7 {The computer's evaluation still
hasn't changed, but my plan is now becoming clear. Get the king over to the
queenside to prevent his g-pawn from moving, while not allowing his rook to
penetrate into the position. Once I can get rid of his g-pawn, my rook will
simply swing over to the queenside to hit f6 and c6, and all his pawns will
fall.} 44. f3 {Keeping the g-pawn fixed!} Ke7 45. Ke3 Kf7 46. Kf2 Ke7 47. Nf1
Bf8 48. Nh2 Kf7 49. Ng4 {The knight is targeting f6 and now the king will move
up and help exchange off the g-pawn. We just don't need it to move forward.
Finally, the computer sees something changing!} Be7 {[#] Now the computer
expects to move the rook around, but it still can't go anywhere. Black can
keep it back. The computer also suggests moving the knight around, but it
still can't go anywhere effectively. But the one move that breaks Black’s
position is removing the g-pawn.} 50. f4 gxf4 51. Kf3 Bf8 52. Kxf4 Bg7 53. Kg3
