{We've already examined Moulthun's successful SIO, but another Australian who
excelled in the Doeberl Cup and SIO was our newest IM, Junta Ikeda, who scored
IM norms and was playing for a GM norm in the last round of both tournaments.
Let's look at his best games from those events. First of all, Junta's win
against Russell Dive is one move too long to be a miniature, but is a striking
game nonetheless.} 1. Nf3 d5 2. c4 c6 3. e3 Nf6 4. Nc3 e6 5. Qc2 Be7 (5... Nbd7

Anti-Meran with 6.d4 (where Black's dark-squared bishop belongs on d6).}) 6. b3

Nbd7 7. Bb2 O-O 8. Be2 {would be a more normal continuation; sometimes White
goes for Rg1/g4 as in the game to start a kingside attack (and then the bishop
on b2 is not obstructed by a pawn on d4, thereby supporting the kingside
attack directly), but if Black pre-empts that with} e5 {,} 9. O-O a6 10. d4 e4
11. Nd2 {gives White a fairly good Reversed French position - he will play} Re8

initiative with a later e3-e4 break.}) 7. Bb2 Na6 8. a3 O-O 9. Rg1 (9. d4 {
would be a normal continuation, leaving the a6-knight out of play (amusingly
enough the engine suggests} Nb8 {and ...Nbd7 to bring the knight into the game)

Now Black should be fine as White's attack is a lot less effective with the
pawn on d4 (instead of d2). But Black curiously decides to re-open the
diagonal.} c5 $6 (12... b6 13. g4 a4 14. b4 dxc4 15. Bxc4 Bb7 16. g5 Nd5 17.

position, emphasises the initiative over structural considerations.}) 14... g6

already.}) 15. g4 (15. Ke2 Qc7 16. Rgd1 Nd7 17. Kf1 Nxc5 18. Be5 {and Nd4-b5

developed is more pointed.}) 18. Bb2 a4 19. h4 $1 {Even without Black's
useless last move he would be under strong pressure, but now the White
initiative is nearly decisive. Black really suffers from half his army being
out of the game.} Qa5+ (19... Qb6 20. h5 Qb3 {at least makes it to an ending,
though Black's unlikely to hold after} 21. Rh1 Qxc2 22. Bxc2 Ra6 23. Ke2 {.})

his knight will find a comfy perch on e6. It's quite hard for White to use his

side.} 22. b3 Nc7 23. Rd3 Ne6 24. Be3 Nc6 25. Rd7 Kf8 (25... Bg5 26. Nxg5 Ra1+
