Yes similar / same theme. After Qxh6 Nh5 Bxb4 Kxb4 the king is in 'the square'
for both pawns but cannot stop both of them.  Some engines have routines to
handle this (e.g. latest Crafty) which helps.  Interestingly I didn't see as
much 'freezing' as with the original position.

All using my 1.5 GHz P4

Program			Negative	Alternative
Yace			55		59
Monarch			5 min 9 sec	5 min 28 sec
Shredder 6.02		4 min 11 sec	4 min 18 sec
Fritz 7			36 sec		39 sec
Tiger 14		-		5 min 24
Crafty 18.10		1 min 25 sec	1 min 26 sec
Crafty 18.14		15 sec		49 sec
Junior 7		> 1 hour!!!
LGoliath 1.5		-		55 sec

The new past pawn routines in Crafty show up nicely!

Regards,

Steve
