In chronological order, here are Pakistan's 10 most painful losses since I've been following cricket:

• Melbourne 1985 (B&H Final vs India)
• Lahore 1987 (WC SF vs Australia)
• Bridgetown 1988 (3rd Test vs WI)
• Bangalore 1996 (WC QF vs India)
• Lord's 1999 (WC Final vs Australia)
• St. John's 2000 (3rd Test vs WI)
• Kingston 2007 (WC Group Match vs Ireland)
• Johannesburg 2007 (T20 WC Final vs India)
• Sydney 2010 (2nd Test vs Australia)
• St. Lucia 2010 (T20 WC SF vs Australia)

Which do you think is the most painful? Try not to let the fresh wounds of St. Lucia affect your choice; naturally it hurts the most right now. But which one is the most painful overall?

Any other suggestions are welcome. This is just my personal top 10.
