Hey guys would like to know what you think about this hand.

First off I think I could have taken a different line with this spot. My flop sizing probably have been more like 450k to 480k on this texture, would usually barrel turn around 60-70% pot but villain in question is very sticky, floaty, bluffy and generally able to make moves. I was under the impression he would take a stab if checked to a large portion of the time, allowing me to crai on turn. He was the chip leader with about 9m chips not long ago but has been splashing around taking some questionable lines and making big moves, applying pressure to the smaller stacks.

As played on the river do we think that we should call the shove? The hand really made no sense to me. All his sets would bet turn, 109s would bet turn, 78s would bet turn. At the same time it doesn't seem like the line he would take as a bluff although from what I've seen he is capable.

Any ideas or comments appreciated. Cheers.
