Right Confession Time, for a couple of years after I started playing live, I understood the principle of tacit cooperation to try and eliminate an opponent, and in general if involved, was happy to cooperate to see everyone move up the ladder. Unless I had the absolute nutz I would happily check it down, and fold strong hands to an active opponent on the basis that he would only bet with the nutz.
However about 2 months ago that all changed with an incident on the bubble at my local casino.
60+ players down to 10, 9 for the final table 9 get paid.
I'm on the button with

all fold to me, I make it about 8k to go, blinds were 1000/2000, or there abouts, SB pushes for about 7k more BB calls, I call.
Flop K high with nothing for me BB check Me check.
Turn A check check
River

Ive made bottom pair nothing really but big blind dutifully checks, by this time we have got an audience from the other table all of whom are willing our small blind out of the tournament.
Now I had been chip leader on my table for a fair part of the night, but had found it increasingly difficult to get any action on my stronger hands. So I decided to do a little advertising here, I had the BB covered by about 4 - 1, so I put him all in, there were murmers of what is he doing, and comments to the fact that I must have at least a set. BB reluctantly passed showing KQ and we were on our backs
SB had pocket

so he comfortably survived, and the lad who was bb in that hand bubbled about 3 hands later.
MY POINT This was not in my opinion a Novice play by myself, it was to send out the signal that this guy is weak and should not be allowed to bully with his chip stack.
It worked as well, as the final table lasted less than 2 hours and I got many speculative calls into my stronger hands and won quite comfortably.
Passage of incorrect information is part of the game, and I took this chance to feed some out to the rest of the people who were going to be on the final table.
Although my reputation in that card room was shot to bits at the time
