Here's a short game featuring the King's Indian Attack formation vs. the French Defence; if Black wants to make a KIA player drool with anticipation (and then hopefully pull away dinner at the last second) then this old 'main line' (with Black castling short, and then concentrating on all-out queenside expansion) is one that White may still dream about facing even these days:

[Result "1-0"]
1.e4 e6 2.d3 d5 {Nowadays a Sicilian Defence-style setup starting with 2...c5 is sometimes recommended here.} 3.Nd2 Nf6 4.Ngf3 c5 {Black could try to dispense with this move, especially beginning with 4...b6.} 5.g3 Nc6 6.Bg2 Be7 7.0-0 0-0 {A big alternative here these days is 7...b6, often following up with ...Bb7, ...Qc7 and eventually ...0-0-0, when Black might be able to launch his own attack on the kingside.} 8.Re1 b5 {Black still has a number of alternative plans here.} 9.e5 Nd7 {The most played, but 9...Ne8 is also possible.} 10.Nf1 a5 11.h4 b4 {In case of 11...a4, as in the famous Fischer-Mjagmarsursen, Sousse (izt) 1967 game [see wiki link earlier in this thread], following Fischer's 12.a3, Black supposedly has issues after playing ...b4, as playing the useful move ...Ba6 before a trade on a3 could then drop Black's a-pawn. However, Chess Assistant 16 (and Houdini3) is unimpressed, and gives a number of continuations where Black is supposedly doing well, even after 12...b4 - but maybe things aren't so simple, as White's play may take time to unfold. Yes, even the KIA can have some fairly heavy theory in places.} 12.Bf4 Ba6 13.Ng5 {Another choice is 13.N1h2, but White's move quickly introduces a trap. Note that if 13.a3?! Black can now play 13...bxa3 14.bxa3 and make the useful move ...Rb8, as he hasn't spent a move on the now less useful ...a4 (K.P.).} Qe8 {A resourceful move for the defence, if followed up correctly, though at least Minev doubts that it gives Black sufficient counterplay vs. White's attacking chances. CA16 gives 13...h6 as very good for Black, as played by just one average master, but this looks to me like by playing ...h6 at this stage, Black just might be asking for trouble at some point.} 14.Qg4 {14.Qh5?! Bxg5! 15.Qxg5 [15.hxg5 f5! also should give Black a big edge] 15...a4 16.Ne3 Kh8 17.Rad1 h6 -/+ Browne-Uhlmann, Amsterdam 1972.} a4 {Falling for the trap! Instead 14...Kh8 (best - CA16) is given as unclear by Uhlmann, and scores 5 wins to 4 (no draws) for Black in CA16. Even here, CA16 gives other moves that are at least playable for Black.} 15.Nxe6 {Black resigns, since after 15...fxe6 16.Qxe6+ the N/c6 is loose.} 1-0
I think I did drool lol - thanks Kevin
