I think the bubble has just burst. I think there were 8 or so at the table. Blinds are 4000/8000 ante 1000.
I think I was UTG, Villian is Marc Wright and he is sat 2 to my left. He has been sat two to my left on two different tables for several hours (FML). He knows who I am and has played me online. No idea what notes he has, but due to his presence two to my left I have avoided a lot of spew during the day. I am reasonably sure I have been playing tighter than I normally would online.
I have just over 300k at the start of the hand, Marc has been running over the table and has a gazillion (well close to a million).
I open to 16K with

. Marc calls, everyone else folds.
The flop comes

,

,

I bet 25k, he calls.
Turn is

, I check and Marc checks behind.
River is

, I lead 50k, he pauses for a while (maybe 30 secs) and then raises to 130K. We have about 230K back.
I say "why did I bet?" and tank.
What now?
