Yes, but it still plays Bxh6, which was the main exercise on my part.

The move is also selected by Comet (at least for the moment):

1.Bxh6 gxh6 2.Qxh6 Nf8 3.e5 N6h7 4.Bxh7+ Nxh7 5.Qxe6+ Kh8 6.Nd5 Bxd5 7.Rxd5 dxe5
8.Rxd8 Rxd8 9.Nxe5
  ±  (0.86)   Depth: 12/35   00:05:06  77909kN

What move does Hiarcs select?

Maybe there's a penalty for exchanging pieces when the opponent king is exposed
(?).

Mogens.

PS: I see that Denmark and Israel drew at the Olympics in Turkey. The game on
the 2nd board seemed very strange when I watched some of it live. It looked like
a win for Avrukh.
