NL 27/ TD question
 
this situation came up durring a nl27 game, but the question is still useful for triple draw. it was allin before the draw. 1st player takes 3. and now i need to decide. draw 1 to an 8 or stay with an A. i decided to stay.

i know that a J is a favorite to a 1 card draw. but the question is what is the worst hand u can have that is a favorite to a 2 card draw? 3 cards draw?

Here's what my tool says about drawing 3 to 72AAA:

<font class="small">Code:</font><hr /><pre>
7 5 4 3 2 0.00394696 0.00394696

Q-high 0.110515 0.331545

A-high 0.0444033 0.518039
pair of deuces 0.140611 0.658649
...
</pre><hr />

So, a rough A is probably a slight dog, but K-high is a 53% favorite. (Actually, in this case if you have an A your opponent cannot possibly get an A--- removing the fourth A puts him at a K or better 50.5% of the time.)

Drawing two to 723AA:

...

Here you need Q-high. Similar results for drawing to 234AA.

However, just because standing pat makes you a favorite does not mean it's the most +EV choice...

Mark: giving villain all aces has a HUGE impact on the results, twodimes is saying about a 10% swing.

Anyways, you should be a favorite over a draw, but you really need to draw yourself

Yeah, I'm not surprised. Taking three of anything out of the deck is going to affect that rank. I should upgrade my tool to explore a variety of holdings (like 27 + three random high cards.)

What is the highest card villian should keep here and draw two instead? J, T, or 9? Or none?

Re: NL 27/ TD question
 
If hero is drawing to 8753, a 9. If hero is pat, he should keep any card up through a K, i think.
