Re: Boring TD last draw question.
Twodimes is suspect on 2345 draws because it does not treat A2345 as ace-high. This can be a 2-3% swing.
I would never keep the Q if my opponent drew one and there is money left. If he has a draw as poor as 9763x (where, note, you have killed 4 of his outs) you are a bare 51/49 favorite. Twodimes puts you as a 51/49 dog by drawing. That 2% equity is probably not worth having to make a tough river decision (unless you autofold? in which case your equity takes a beating anyway.)
In fact, I think the twodimes number is incorrect by enough to make your EV slightly higher by drawing. My spreadsheet calculation puts you at 0.517 by drawing while twodimes reports you at 0.512 by standing pat.
If Villian draws two I would definitely keep it. If Villian has a stronger 1-card draw you're behind either way, but I think last-round considerations require a draw even if the chance of the Q holding up is a bit larger.
