€110 buy-in live tournament in Rozvadov (side event to WSOP Circuit event) - but buy-in and live vs online shouldn't matter much, I believe, as it is a "standard" / basic preflop spot.
Blinds are 500/1k/100, I have a stack of about 20k, average around 33k. It folds to me on the button with A8o, both blinds have me covered. I don't have particularly relevant information on the two players still to act, as I was moved to the table not long ago.
I open to 2300 - shoving would be +EV but risking stack for too little gain, I believe. With <15BB left it would be an easy shove, I suppose (?)
SB raises to 6400, BB folds.
I believe I can only shove or fold - which one is better vs an (almost) unknown?
