I'm playing heads-up trying to start a 6max table, this is one of the first hands since this guy sat down, nothing has really happened yet. I'm mostly interested in gameplan/options/adjustments in this spot. I 3bet QQds with connected side cards, get called, and flop good but not great on a board texture that's bad for my 3betting range. I check, as I would usually do with most of my range on this board...but when he bets I'm not sure of the best way to continue. I lean towards check-calling as I don't think raising accomplishes too much, but I don't know. Is there any merit to a check-raise here, and if so, what's a reasonable sizing? Do we want to have both a check-shoving and check-raising small range?
