Rebel 10 PII-450 60MB HT (anti-GM=smart)
mm:ss ply  eval moves
------------------------------------------------------------------
00:09 6.00 6.23 Be4xa8 Nf5-d6 Ba8-d5+ Kg8-h8 Rf1xf8+ Qd8xf8 Qd1xa4
00:26 7.00 6.21 Be4xa8 Nf5-d6 Ba8-d5+ Kg8-h8 Rf1xf8+ Qd8xf8 Qd1xa4
01:55 8.00 4.03 Be4xa8 Nf5-g3+ h2xg3 h4xg3 Rf1xf8+ Qd8xf8 Ba8-d5+

<g4 not played within 5 minutes>

If you try <analysis include g4>, results are as follows:
mm:ss ply  eval moves
------------------------------------------------------------------
00:26 7.00 2.89 g2-g4 Ra8-a7 g4xf5 Bc8xf5 Be4xf5 Rf8xf5 Rf1xf5
01:14 8.00 2.80 g2-g4 Ra8-a7 g4xf5 Bc8xf5 Qd1-c2 Ra7-c7 Be4xf5
04:11 9.00 3.01 g2-g4 Ra8-a7 b5-b6 Ra7-f7 g4xf5 Bc8xf5 Be4xf5
11:43 10.0 3.12 g2-g4 Ra8-a7 b5-b6 Ra7-f7 g4xf5 Bc8xf5 Be4xf5

It seems as if Rebel 10 will not "find the move g4 in very short time".
