I should probably be shoving here but for some reason I am being cute and planning on raise/calling. An even shorter stack flats me on the button. What do we take his flat to mean? And should I be shoving any flop given that he has about the pot behind, or check/folding because he is unlikely to bluff with a hand like AJ/KQ?

No reads but my PokerTracker shows him limping/calling frequently and rarely riasing preflop over a small sample. He is also a slightly losing player over an insignificant sample size according to ORP but his results aren't too bad in these tourneys, which are all he plays.

shove pre

as played check/fold flop. when stationy players flat 25% of their stack they almost always have pocket pairs and are never folding.

also, the times they don't have pairs, they usually have suited connectors, which could have easily connected with this flop. big cards like AK/AQ are among the few hands that this type of player would raise or shove pre instead of flatting.

Interesting. I'd love to see other posters' opinions of this train of thought. Anybody else agree with intclock?
