This happened twice today with different players.

UTG limps, then it is folded to me in CO (the other time in BU). I have good cards so I raise to 4xBB. It is then folded to UTG who re-raises about 3x my raise.

Both times, I had only about a dozen of hands on the villain with nothing of note seen. So no significant reads.

What should I make of such a move? Should I simply consider it a normal re-raise? What kind of range can I put villain on?

Both times I ended up folding because my cards were not good enough to 4bet and I was lost in terms of putting villain on a range because of their weird move.

Any help would be appreciated.
