This next commentary game contains some themes for improving players at several different levels of analysis - meta, strategic, and tactical. "Meta" in this case refers to the overall context - the fact that GM James Tarjan, one of the best US players in the 1970s, was at the time of this game in the third year of his chess career comeback and at age 65 defeated both GM Alexandra Kosteniuk (below) and super-GM Vladimir Kramnik during the 2017 Isle of Man International. This was no fluke, as he had also played for the US in the 2016 chess Olympiad. Seeing these kinds of examples helps combat the "inevitable decline" narrative associated with the aging process, or at least provides fewer excuses for not undertaking effortful study.
While we (or at least I) may not have Tarjan's level of inherent talent, his approach and the example of play here are understandable and instructive. My top observations from the game:
- Tarjan's opening choice is designed to allow White to "play chess" rather than debate opening theory. This strategy used to be frowned upon in general, with purists insisting White always play for a forced if slight advantage. However, Carlsen's repeated use of it over the years has lent it more legitimacy; one game of his is in a similar variation is included in the game notes.
- Master-level choice of candidate moves. I highlight multiple instances where White's move choice probably would not occur to an amateur. I find these to be one of the most important aspects of studying and analyzing master-level games, as they demonstrate how new ideas can be introduced into your own play.
- The interplay of tactical and strategic considerations is evident throughout, especially when Black - probably under time pressure - starts missing key tactics in the latter part of the game. Using tactics to achieve more of a strategic/positional advantage was also possible at several points in the game for both sides.

-Nepomniachtchi,I (2784) Lichess.org INT 2020}) 7. Bb2 {the bishop must
develop here and there is no reason to postpone it. It also gives White a look
at Black's next developing move before making any other decisions about piece
placement.} Nc6 (7... O-O {seems more consistent with the early Bishop move,
also waiting to see where to go with the Nb8.}) 8. Bxc6+ $5 {Tarjan is the
only one in the database to play this, sending the game on to a different
strategic path. It is a classic trade-off decision, eliminating the strong
White bishop but inflicting permanent structural damage on Black and providing
White with relatively easy targets to work against. The engines evaluate the
position as equal.} (8. Nf3 {is of course the conventional move.}) 8... bxc6 9.
Nf3 {developing and attacking e5.} Qd6 (9... f6 {would be the more standard
way to protect the pawn in similar Black structures.}) 10. O-O {tucking the
king away before Black can play ...Bh3. Interestingly, the engines do not
consider this such a problem.} (10. Rc1 $5 {immediately moving to increase
pressure on the c-file.} Bh3 11. Qc2 $11 {White's king is in no danger and the
rook can go to g1 and still be useful.}) 10... Bf5 $6 {this fights for the e4
square, but not very effectively, considering White's next move.} (10... Bh3) (
10... O-O) 11. d3 $14 {now White is threatening Ne4, with a discovered attack
on the e5 pawn.} Qe6 {avoiding a double attack on the queen after White's next.
} 12. Ne4 {Black now has an important strategic decision to make. Her choice
to castle queenside is very imbalancing and appears to go against the
position's needs. Kosteniuk must have felt that either the king was safe
enough there, despite the weak pawns, or that she would be able to attack
White first.} O-O-O $6 {Black tactically protects e5, as the Ne4 is now
hanging due to the pinned d-pawn. However, White gets out of the pin by moving
his queen to a better square, lining up on the c-file, so it is a net minus
for Black.} (12... f6 {is the engine recommendation, protecting the pawn.}) (
12... Bxe4 $6 {looks like a reasonable idea, inflicting some pawn structure
damage on White in return. However, Black's c-pawns are still worse than
White's e-pawns and Black would no longer have the two bishops.}) 13. Qc2 $16
f6 14. Rfc1 {putting a rook on c1 is clearly a good idea, creating a battery
with additional pressure. An argument could be made for moving the other rook,
since the a-pawn will not need its support to advance, but White evidently
wanted to put both heavy pieces on the queenside.} Kb7 {a reasonable-looking
defensive move, but Black may be better off looking for some counterplay.} (
14... Bg4 $5 {is the engines' preference, threatening to exchange on f3 and
undermine White's d-pawn.}) 15. b4 $5 {a move that no amateur would be likely
to consider, as it just appears to lose a pawn.} (15. a4 {is the more obvious
way of launching operations on the queenside.}) 15... Bxb4 16. Rab1 {now we
see the idea of the pawn sacrifice, to attack down the b-file. It appears to
be slower than alternatives, though, as Black looks to equalize with ...Rd5 or
exchange off an attacking piece with ...Bxe4. In practical terms, it is still
difficult to meet, however.} (16. a4 Rd5 17. a5 Nd7 18. Bxe5 $5 fxe5) 16... Be7
{withdraws the bishop from its current vulnerable square, eliminating tactics
involving a discovered attack after the Bb2 moves (for example Bd4 or Bxe5).
This does little to impede White's attacking ideas, however.} (16... Rd5 {
this defends along the 5th rank, although White still has pressure and
tactical ideas in the center against the rook and bishop. For example} 17. Bd4
Ba3 18. Nc5+ Bxc5 19. Bxc5 e4 20. Nd4 Rxd4 {the defensive exchange sacrifice
is necessary} (20... Qd7 $2 21. dxe4) 21. Bxd4 {at this point the engine shows
complete equality, despite the material difference, meaning that with accurate
defensive play Black will be all right. If Kosteniuk calculated this far,
however, it would hardly look appetizing.}) (16... Bxe4 $5 {may be the best
practical choice here, eliminating an attacking piece and reducing complexity.}
17. dxe4 a5 {physically impeding White's future a-pawn advance} 18. a3 Be7 $14)
17. a4 {with the idea of pushing away the knight. Bringing another piece into
the attack might boost its effectiveness.} (17. Nfd2 {appears to be a useful
preparatory move, as the Nf3 now is not doing much otherwise.}) (17. Bc3) 17...
Ka8 {getting off the open file.} 18. a5 Nd7 {although Black has been pushed
around, White does not have anything decisive and now looks to recover the
pawn. However, there is no rush to do so and he ends up in a slightly worse
position with the move played, so alternatives are worth looking at.} 19. Qa4 (
19. Ra1 $5 {with the idea of Ba3 and trading off White's worse bishop, helping
fight for the dark squares onthe queenside.}) (19. Qxc6+ Qxc6 20. Rxc6 {
regains the pawn more forthrightly and seems to give Black less leeway than
the game continuation.}) 19... Rb8 {challenging on the open file and giving
back the pawn for equality.} (19... Nb8 $6 {is a move amateurs might play,
defending the c6 pawn at all cost. This would renew White's attacking chances,
however. For example} 20. Nfd2 Rd5 21. Ba3 Bxa3 22. Qxa3 Na6 23. Rc4 {followed
by Rbc1.}) 20. Rxc6 {this forces Black's next move, otherwise the c-pawn is
lost.} Qb3 21. Qxb3 Rxb3 22. Nfd2 {finally the knight gets into the action.} (
22. Rxc7 $2 {greed is punished by} Rhb8 23. Rc2 Ba3 $19) 22... Rb7 {now Black
is doing fine and the open b-file is more of a benefit for her than it is for
her opponent.} 23. Rc2 {this overprotects the Bb2, freeing the Rb1 to move,
but seems a bit passive.} (23. a6 $5 Rb6 24. Rxc7 Rhb8 25. Rc2 Rxa6 {with a
slight advantage to Black, with the passed a-pawn.}) 23... Rhb8 24. Nc4 {
overprotecting the Bb2 again and getting the knight further into play.} a6 {
physically blocking the further advance of the White a-pawn.} 25. Rbc1 {
moving the rook out of the pin and doubling pressure on the c-file. White has
managed to rearrange his pieces to be less awkward and can look to exchange
off his worse dark-square bishop with Ba3.} Rb3 {this temporarily stops the
bishop exchange idea, but White could still insist on it.} 26. Bc3 (26. Ned2
R3b5 27. Ba3 Bxa3 28. Nxa3 Rxa5 29. Nac4 Rc5 30. Ra2 Rc6 31. Rca1 $11 {with
play against the a-pawn.}) (26. f4 $5 {could also be played immediately.})
26... Be6 {Black again passes up the chance to exchange on e4. This seems to
help validate White's previous move, though, as the bishop is now more useful
on the a5-e1 diagonal protecting the a-pawn.} (26... Bxe4 27. dxe4 Nc5) 27. f4
$6 {one of the common cases where playing the right idea at the wrong time -
one tempo later, in this case - could result in a setback.} exf4 {Black makes
the obvious move, to avoid losing the e-pawn (attacked three times, defended
twice).} (27... Bxc4 {this possibility is the difference.} 28. dxc4 exf4 29.
gxf4 Nc5 30. Ng3 Bd6 31. e3 $17 {now White has three weak pawns (a5, c4, e3)
to defend and Black's pieces are much better placed.}) 28. gxf4 {this allows
Black to play ...Bxc4 again, but she overlooks this.} (28. Ncd2 {is the
engines' recommendation, sacrificing the pawn for vigorous piece play.}) 28...
R3b5 29. Bd4 $11 {now White is completely equal.} Bb4 {attempting to pick up
the a-pawn. Komodo recommends to simply ignore it, as White's rooks could then
make threats on the c-file.} (29... Bxc4 30. Rxc4 $11) 30. Bc3 {an equal
defensive move. Given the repetition of moves that occurs here, it appears
both players were likely low on time.} (30. Ne3 $5 {this unleashes the rooks.}
Bxa5 31. Rc6 Bb6 32. Bxb6 R8xb6 33. Rxc7 $16) 30... Be7 31. Bd4 R8b7 32. Kg2 {
White appears to be just marking time here. Perhaps this succeeded in
provoking Black's next, which is a non-obvious blunder.} Kb8 $2 {this appears
to be a reasonable move, getting the king out of the corner and reinforcing
the pawn on c7. It has a tactical problem, though, which Tarjan finds.} (32...
Bd5 {or moving to f7 or g8 would avoid the problem, which is created by the
king making itself vulnerable to a back-rank check, physically blocking the
rook from coming back to b8.}) 33. Ncd6 $1 {an example of a reloader tactic on
d6, made possible by the threat of Rc8+} Bxd6 (33... Rb1 {the engines suggest
leaving the bishop on the board rather than exchange it, but it's still a win
for White, who is up the exchange with no compensation for Black.} 34. Nxb7
Rxb7 (34... Rxc1 35. Rxc1 Kxb7 36. Nc5+ $18) 35. Kf2 $18) 34. Nxd6 {and now
Black loses material.} Rd5 35. Nxb7 Rxd4 36. Nd8 Bd5+ 37. e4 Kc8 38. Nc6 Bxc6
39. Rxc6 Rxd3 40. Rxc7+ $18 {at the end of the sequence, White is simple an
exchange up with a dominating rook pair.} Kd8 41. Ra7 {both getting behind the
a-pawn and leaving the c7 square potentially available for the other rook.} Rd6
42. Kf3 g5 {attempting to get any counterplay possible, by breaking up the
pawn shield in front of White's king, or getting a kingside pawn majority.} 43.
Rg1 h6 {this looks like it is reinforcing the g-pawn, but ends up giving
another pawn to White.} 44. h4 {another interesting master idea, although an
amateur might have more of a chance of spotting this tactic. The h-pawn cannot
be taken due to the mate, and Black's g-pawn cannot be further reinforced, so
it is lost.} Ke7 45. hxg5 hxg5 46. fxg5 fxg5 47. Rxg5 Kf6 48. Kf4 Ke6 49. Rg6+
Nf6 {allowing one final tactic.} 50. Rxf6+ {and now the pawn forks on e5 after
the rook is recaptured.} 1-0
