cruising for a while

I was cruising along in the $5-quad and the $3r with 100bb stacks until just now.

With blinds at 200/400 UTG +2 opened for 1000.  I 3bet KK to 2888 from the CU.  He called.  Flop was Q64.  He open shoved 8k, I called.  He shows KQ.  River Q.  Sittin with 21k with blinds at 250/500.

Got 57k with blinds at 350/700 in the $5-cubed.
