Spots like these always tend to make me spew. I don't know what it is but I always feel like I should shove in these spots because 'I still have some equity if they call' + 'I have fold-equity'. To be honoust I'm very confused about it so I would apreciate if you guys can tell me what you would do in this spot.

thank you

PS: I know that I have to put him on a range and I always try to do that, but I would appreciate it if for this time you guys could tell me what your think his range is on the flop and what you think he's calling/folding.
