What do you know about donk's barreling tendencies?
If he's the type that fires one with his 63o, 55, 66 hands to see where he's at than just call and play turn perfect.
If he's the type that donks his draws and marginal pairs, calling any raise and checking any turn.. then raise and get a cheap showdown.
If donk is mega aggro and will click it back often, sometimes even jam / reraise big with a ton of hands, then obviously just call
In general when donks first lead into me on this type of board I raise it up with a very wide range to see what happens.
