[I.Rowboat]

I don't think this approach is necessarily wrong, but a lot depends on the remaining players.

I would probably take a different line, which is to check the flop with the intent of c/r when it comes back around. Our Q may be dominated, but we do have outs, and this will almost certainly clear the slop and get us HU with the original bettor...and if it doesn't, e.g., if we're three or more to the turn, then we know we're very likely against a FD, OESD, and/or better Q, and can play the turn accordingly. In short, I think the extra SB on the flop makes it a lot easier to play the later streets.
