Subject: tricky endgame

This is from a recent game Arasan-Postmodernist on ICC:

[D] 5k2/ppp5/7p/4Q3/4P3/P4q2/1P3P1P/6K1 w - -

Crafty analysis output:
 30.    Qf5+
                ({14:-0.46}  30. Qf5+ Qxf5 31. exf5 Ke7 32. f4 Kf6 33. Kf2 Kxf5
34. Kg3 c5 35. Kh4 Kf6 36. Kh5 Kg7 37. f5 b5 $15)
                ({14:+1.92}  30. Qe6 Kg7 31. e5 Qe4 32. h3 Qb1+ 33. Kg2 Qg6+ 34.
Qxg6+ Kxg6 35. f4 Kf5 36. Kg3 a5 37. Kh4 Kg6 38. e6 Kf6 $18)
                ({14:+1.11}  30. Qd4 Ke7 31. Kf1 Ke6 32. Qd5+ Ke7 33. Ke1 b6 34.
Qe5+ Kd7 35. Qg7+ Kc8 36. Qh8+ Kb7 37. Qe5 Ka6 38. Qxc7 Qxe4+ 39. Kd2 $16)
                ({14:+1.13}  30. Qh8+ Ke7 31. Qh7+ Kd8 32. Qg8+ Ke7 33. Qg7+
$16)

In the game, Arasan played Qf5+ and eventually lost. Arasan 5.4 wants to play
Qf5+ even after 10 minutes search on an Athlon 1.3GHz. Arasan 6.0 does switch to
Qe6 eventually, but it takes a long time (about 8 minutes).
