Returning to the second round game, an English opening versus a King's Indian Defense setup, it features an all-too-typical pattern of an opening advantage in space and time squandered by too-slow play, then the selection of an incorrect plan based on a lack of appreciation for my opponent's possible threats. This points to the need for deeper study of the middlegame transition point, in this case moves 10-13, where improvements were found for White.

{A16: English Opening: 1...Nf6 with ...d5} 1. c4 Nf6 2. Nc3 g6 3. g3 Bg7 4. Bg2
d6 5. Nf3 Na6 {exactly one game in my database (out of 2500+ with this
position) has this move. Castling is the overwhelming favorite at this point.}
6. O-O Rb8 {now out of the database. Black intends to apply ideas similar to
the Panno variation with the early Rb8.} 7. d3 {the standard English setup
against the KID. The e4 square is covered and the c1 bishop released. Also,
Black does not have a target with ...e5.} c5 8. Rb1 {initiating the standard
plan of queenside expansion by pushing b4.} Nd7 9. Bd2 {protects the Nc3 and
allows the idea of Qc1 and Bh6 to exchange off the Bg7.} Nc7 10. a3 {this is
too slow to take advantage of Black's relatively passive play and uncastled
king.} (10. b4 cxb4 11. Rxb4 O-O 12. Qc1 {would keep the initiative and a
space advantage.}) 10... b5 11. cxb5 Nxb5 12. Nxb5 Rxb5 {now the point of
Black's early Rb8 is seen, as this series of exchanges would not have been
possible otherwise. Black as a result has more space and play on the queenside.
} 13. Bc3 {again a slow approach.} (13. b4 O-O 14. Qc2) 13... O-O 14. Bxg7 Kxg7
{White's earlier advantages in space and development are now gone.} 15. Qc2 Qb6
16. Rfc1 Nf6 17. Qc3 ({Both Fritz and Houdini show} 17. Nd2 Be6 18. Nc4 Qa6 $11
) 17... a5 ({This suffices to give Black an advantage. Houdini points out the
immediate bishop development} 17... Be6 {would threaten Ba2 and Rxb2.}) 18. d4
{this was the idea behind White's erroneous Qc3 plan, which however did not
take into account all of Black's threats.} (18. b3 $5 {instead is necessary in
order to avoid losing material.}) 18... Bf5 {Black gets deadly initiative, as
Fritz puts it.} 19. Ra1 Rc8 {now White cannot stop Black from crashing through
on the queenside.} ({Worse for Black is the immediate capture} 19... Rxb2 20.
dxc5 dxc5 21. Qxc5) 20. Nd2 $2 (20. d5 {is the best chance} Rb3 21. Qe1 Rxb2
22. Nd2) 20... cxd4 $19 (20... Rxb2 $2 {doesn't work due to the knight fork}
21. Nc4 cxd4 22. Qxb2 Qxb2 23. Nxb2 $18) 21. Qf3 Rbc5 (21... Rxc1+ $5 {and
Black can already relax} 22. Rxc1 Rxb2 $19) 22. Rxc5 Rxc5 23. e4 $2 {a last
attempt by White at a counterattack.} (23. Qb3 $5 {was objectively best for
defense}) 23... dxe3 24. Qxe3 Qxb2 25. Re1 Re5 {and White has nothing left.} (
25... Re5 26. Be4 d5 27. f3 Re6 28. g4 Bxe4 29. fxe4 Nxg4) 0-1
