Flop and turn are both good.

River is interesting. BvB I would expect villain to call you on the turn with a lot of his showdown value without a club, so we can probably fire a third barrel to get him off at least 8x and probably Qx. Our pair of 6's isn't really worth anything so should do better as a bluff

When I saw this run out my immediate thought was to fire a 3rd barrel expecting to fold a good portion of their range. I'd make it like $2.20.

Interesting! Thanks guys! Gotta go grow me some balls for that third barrel at these limits
