Moved to the table 3 orbits ago. Table has been pretty solid minus one monkey who just got railed. I 3-bet villain 2 orbits earlier w/ JJ (didn't show). 5 hands ago I folded to his 5bb preflop raise after limping with 77 along with 2 other limpers before me. Could have raised myself, but stole blinds 2 of the last 7 hands and figured I would cross my fingers for a 7. Now this hand:
