Now I think this is an extremely standard hand in a hyper turbo. I don't think ICM implications are much of a factor in a hyper turbo when on the final two tables as the blinds move so quickly, and with a tiny stack (<4bb) I dont think you can pass up such a hand. Nevertheless, I shoved, and lost, and I put it down as standard. But my friend who was railing me said they disliked my shove, and later emailed me saying shoving there with 99s is suicide! This has me totally confused, and I was wondering whether or not they have a point, should I tighten up in such a spot? Or should I carry on as I was?
