Qxh6 Qa5 3. Ng5 Ne5 4. Bh7+ Kh8 5. Be4+ Kg8, you have the non-forcing, non-check move 6. h3! which keeps the knight on e5 from going to g4, and most chess programs will not extend their search beyond it at that depth. After 6. ... Ng6 7. 0-0, Black is forced to exchange his queen for two minor pieces, and white has a won game. I am trying to put together a set of Nolot-type positions, and this one is going in my collection.
