Assuming all players are at least average+, being 50 out of 1000 left, and new to the table...

Chardrian in this position (UTG+2) would raise with TT-AA, AK, AQ suited or not...the range could be wider, but as a new to the table I would think not.

Homebush could call the initial raise with a wide range of hands...any pair 55 or greater, 9T suited or better. However, I would expect a reraise/push from him with JJ - KK, AK and maybe AQ suited...that won't always happen.

bigmoney1 could push with any pair say 33 or better, Ace and any kicker higher than about 3, probably suited, AK/AQ/KQ...

Now, would reasonable players do this? Probably not - but it's not that unusal in a tourney. So - does bigmoney have AA/KK/QQ/AK or is he making a move.

As chardrian, I'm probably only making this call with Queens or better, AK/AQ (probably suited)...readless and new to the table...reads would make the range wider of course.

I would think that homebush would fold anything worse than AK/AQ or nines.

So - final answer time?
Chardrian has KK.
homebush has TT.
bigmoney1 has AQ.
