Will defend 2C doubled but not 3C doubles?

I couldn't keep my mouth shut: [hv=sn=bbradley62&s=SK8HKQ2D73CAJ8642&wn=Robot&w=SHT6DAJ862CKT9753&nn=Robot&n=SJT7643H753DKQ4CQ&en=Robot&e=SAQ952HAJ984DT95C&d=n&v=b&b=13&a=P1S(Major%20suit%20opening%20--%205+%20%21S%3B%2011-21%20HCP%3B%2012-22%20total%20points)2C(Two-level%20overcall%20--%205+%20%21C%3B%2010+%20HCP%3B%2011)PPD(2-%20%21C%3B%203+%20%21D%3B%203+%20%21H%3B%205-7%20%21S%3B%2011-21%20HCP%3B%2012-22%20total%20points)3C(6+%20%21C%3B%2014-18%20total%20points)3D(biddable%20%21D%3B%209+%20total%20points)P3H(2-%20%21C%3B%204%20%21D%3B%205-7%20%21S%3B%2021-%20HCP%3B%20biddable%20%21H%3B%2014-22%20total%20points)P4D(biddable%20%21D%3B%209+%20total%20points)PPP&p=SJSQSKH6D3D8DQD9CQH4CAC3C4CTDKS2D4D5D7DAC5S3DTC2SAS8C7S6S9H2DJS4D6H3H8C6D2STH9C8CKH7S5CJC9H5HJHQHTS7HAHK]360|270[/hv]Would a direct double of 3♣ have been for penalty? If so, why didn't West do this? Strange play on the first few tricks, but nice squeeze at the end.

Not to knock you BB - I see that you realize that 3C was an overbid - but another example of my recent post about bad bids often leading to great results.

 

And certainly there is no obvious reason here for GIB not to double 3C.

Playing these hands in 4♦ after trick 1 makes for a nice double dummy problem :)
