Hey, I'm just a sitter for Barn3tt, and not much of a gunboater, so I didn't know the etiquette of eliminating players for a smaller draw in gunboat, so I merely tried to get Barn3tt the best finish I could. That said, I don't personally distinguish between a 3 way and a 4 way. I wanted a two-way with Turkey. It seemed obvious to me, again, a non-gunboater, that Turkey could eliminate Italy and not threaten the Iberian while I was then allowed to kill off France. Or, worst case, for sure Italy would die and if France saw a three-way, depending on if Turkey did not back off from the Iberian, so be it. When Turkey pushed into Mar, no way I was giving up a solo, and it looked like Turkey could kill off Italy at any time, so I hit the draw button.
Also, it did seem a bit heavy-handed to just back off the line to allow others to be killed, so the helped sway me to hit the draw button, as my best guess is the proper etiquette would have been to just four-way draw a few years back.
