With 160 runners left from 1500 you"re not yet in the money places right? I think as a big stack and approaching the bubble, the last thing you want to be doing is colluding to knock players out. Big stacks can feast hungrily on the shorter stacks approaching the bubble as they"re all generally tightening up to eek into the money places.
Once the bubble bursts those short stacks are going to start pushing and your theiving equity vanishes. Even if you"re in the money, with 160-ish runners to go, 16 tables, still why bother? How much do you get for coming 159th as opposed to 160th? Or 159th as opposed to 100th? Knocking players out when the final tables approaches is when I"d start colluding. If I ever got near a Final table that is.
I think entering this pot with K-10 was a bit dodgy, but post-flop was played very well. The guy was probably just p*ssed off cause he would hit and won the pot, but got out-played.
Not doubt all of this has been said somewhere on this thread already, I ought to have read the previous posts, but my soup is nearly ready.
