heuristic: <10. Ng5 h6 11.Ne4 planning 12.Qh5, then 13.Bxh6! gxh6 14.Qxh6 & 15.Ng5,
since there's no Knight to defend h7.>
to defend h7, you need either a N on f6 or a B on f5.
10.Ng5 h6 11.Ne4 d6 12.Qh5 Be6 13.Bxh6 gxh6 14.Qxh6 Bxd5 15.Ng5 Bf5 16.g4 Bg6
and BLK is in better shape.
The game moves 10.Bg5 Qe8 (10...h6 11.Bxd5 hxg5 12.Nxg5) keeps WHT advantage.
<Or 14.Bg3 Ng6 15.d5 with a chokehold>
Doesn't the B on b6 pin the f2 pawn and renders d5 ineffective?
14.Bg3 Nh5! 15.d5 Qd8 16.d6 Nhxg3
<missed 20.e6 Qxd6 which holds by a thread>
20... Qc6 is interesting. 21.Bf1 Bxe6 22.Qxh6 Nf5 or 21.Bd5 Qxd6 22.Qxh6 Qxd5
<the suicidal 15 ... d5!? only worked because the Bh4 was hanging>
What's dangerous about this? either d5 or d6 is a great move as it frees the QB
15...d6 16.exd6 Qd7 17.Bg3 Nxg3 18.fxg3. interestingly, these moves are appropriate
for 15...d5 also.
to me, 15.Ne4 is suicidal as it depends on a "cheapo",
15.Ne4 Nfxh4?? 16.Nxh4 d5 17.exd6 Nxh4 18.Nf6+!
better is 15.Bg3 Qd8 16.Qc2 d6 17.e6 and WHT continues its stranglehold.
this game is instructive because it shows that for K attacks, you need both
clearance and backup. Boden was fixated on Nf6+ to open up the K, but he had
only the Q for the follow-up attack. You need a 1-2 piece advantage (in the immediate area)
for a successful attack, and with d5, BLK activates the QB and blunts the attack.
