I've read some of the recent posts about how peeling/ folding might be a better play than the 'classic' raise for a free card/ bet turn and take a free showdown that I have used a lot in the past but am now starting to reconsider. This situation seems like a good one for the free card play however. The pot already has 9 SBs, so is large enough to make a play that gives you the best chance of winning it. True, the TAG might get tricky and three bet or donk the turn, and then I guess you have to revaluate. But as the pot is raised and four way, you probably have decent equity against the bettor, the raise to thin the field and hope to improve on the turn is IMO the way to go here.
