It takes Fritz8 and Shredder 7 several minutes to avoid 1...Ng4? on my Athlon XP
1900+ and even some time to avoid the blunder 2...Nf2+??. Even if 2...Ne3+ will
not loose the game immediately there are many better moves than 1...Ng4?

After 1...Ng4+ this line is forced:

1... Ng4 2. Bxe7 Ne3+ 3. Kd2 Nc4+ 4. Kc1 Kxe7

Most engines evaluates this position about +0.5 in favour of white.
