I have no idea what you are talking about.  I didn't q-search checks (both
including checking moves and check evasions) in Cray Blitz and early crafty
versions.  I dumped them just prior to the 1996 WMCCC event because the program
played better.

Whether they would work better now or not is unknown.  If you want to trust
your q-search to find deep tactics, go ahead.  I'd rather back those nodes up
into the full-width tree where results are much more reliable.
