It seems to me that this player was making a play for the blinds and what he perceived to be a weak raise made by a late pos. player testing the waters. This is a pretty standard tournament play. (I would wait a little longer before shoving here.) But his range given that the only info at hand is this single hand, is pretty wide. He's on the cut-off, everyone folds to bluffinclouds who raises 2x bb's, I've executed steals here with anything from T,T down to 2, 3 suited. I wouldn't discount a hand of decent strength here either. Might have been very close. Something like J,J maybe. If I had to guess though I'd probably put him on Pocket pairs (5,5 - J,J) and maybe high suited connectors (8,9 - T,J). Could have hade 2,5 off though, a single hand isn't enough to develop an accurate read on a player.
