What platform are you running on?  And what size opening book are you
using?  Those factors can make a BIG difference in how GNU Chess
plays.

I'm running 4.0.61 with the huge book on an Encore 93 Series (which
uses the 25MHz Motorola 88100 CPU and 88200 cache/MMU) running our
variant of System V called UMAX V.  GNU Chess takes 5 sec. to respond
to 1. h4 with 1. ... e5.  From then on, the moves are taken verbatim
from its book (2. e4 Nc6, 3. Nf3 a6, etc.).

| P.S. Gnuchess also hangs after 1. e4 d6  2. d4 Nf6  3. Nc3 g6  4. f4 Bg7
| 5. Bc4

This line must also be in the huge book, since I get the immediate
response of 5. ... c5, 6. dxc5 Qa5, 7. Bd2 Qxc5, 8. Qe2 O-O,
9. O-O-O Bg4, 10. Nf3 Nbd7.  GNU then starts thinking on move 11 and
came up with 11. Bb3 Qh5 as a continuation.
