I think the Q76 one (holding T9) relates to some of the heads-up play discussed in HEFAP where they recommend just taking the top card and turning it into a deuce in your mind (and you won't be to far off from correct strategy much of the time according to S&M).

Doing it that way...you should think of it kind of as holding T9 on a board of 762 so you're holding over-cards to the board.

Basically....S&M are advocating that you not be scared by one litle overcard (especially if it's not an ace) and that your outs stand a good chance of being clean.
All 8's are good....your 9's and T's are usually going to be good.

I would also consider bet/calling this flop and then possibly donking a rag on the turn.
This might be because I've had a habit lately of taking pots with just one flop bet when I was looking to bet/3-bet a biggish hand.

There are other situations where I like to bet-call but since that's not even an option on these I guess it just shows that I'm not taking/maintaining the initiative enough and that i really shouldn't be doing that.
