Quick Odds

[JC21]

I'm trying to improve my NL play, and I'm wondering if there are any quick preflop odds to memorize. For instance, I know that a pair vs. two overcards is about 50% to win, or that AK has about a 60% chance of beating any two unpaired undercards. What other simple probabilities should I know?

Preflop:
PP v. lower PP: 4:1 fav (around 80%)

XY v. XZ (Y>Z where both have straight possibilities i.e. AQ v. AJ) : 3:1 fav (around 74%)

XY v. XZ (Y>Z, but X cannot make a straight with Y, but can with Z i.e. A7 v. A5) : 3:2 fav (around 62%)

XY v. XZ (Y>Z, but X cannot make a straight with Z, but can with Y i.e. AQ v. A7) : 5:2 fav (around 70%)

XX v. YZ (Y>X>Z i.e. QQ v. A7 and AJ because AJ needs a Q to make a straight) : 2.5:1 (around 70%)

XX v. YZ (X>Y>Z, but YZ connect and don't need X for a straight and YZ are suited i.e. K[img]/images/graemlins/heart.gif[/img]K[img]/images/graemlins/diamond.gif[/img] v. 6[img]/images/graemlins/spade.gif[/img]7[img]/images/graemlins/spade.gif[/img] ) : 3:1 (around 75%)

XY v. ZN (X>Z>N>Y where ZN are suited and connecting and need XY for a straight. i.e. A[img]/images/graemlins/heart.gif[/img]T[img]/images/graemlins/diamond.gif[/img] v. K[img]/images/graemlins/spade.gif[/img]Q[img]/images/graemlins/spade.gif[/img] ) : 5:4 fav (around 55%)

Flop+:
Straight/flush draw is only a 42% dog to a set.

i.e.
A: 6[img]/images/graemlins/spade.gif[/img]7[img]/images/graemlins/spade.gif[/img]
B: 4[img]/images/graemlins/diamond.gif[/img]4[img]/images/graemlins/heart.gif[/img]

Flop: 4[img]/images/graemlins/spade.gif[/img]5[img]/images/graemlins/spade.gif[/img]X

B is slightly worse than a 3:2 fav.
