online-betting Short-handed Play and Hand Values

When you've ploughed your way through the tourney bozos and you're facing just one or two card sharks what exactly are the percentages you're facing? Doctor of Danger investigates.

If you play tournament poker, you’ll be aware that at the final stages when the blinds are big and there are few people left, individuals are forced to play very aggressively just to stay afloat.

More often than not, being in a pot means having to be prepared to commit all your chips.

Additionally you’ll often be faced with a situation where you have an opportunity to ‘steal’ the blinds, or alternatively where you have to defend the blinds. The latter also occurs in cash games!

What many people are not fully aware of is that hands change value in these scenarios – because many/most of the hands go to showdown, because your opponents playing requirements will change and because there is a maximum number of people who can partake in the pot.

What I’ll look at here is how valuable hands are in a heads-up situation where they go to showdown. I’ll then explore how these values change as we add an extra player or players. Finally I’ll look at some of the strategy implications in terms of going all-in or calling an all-in.

The first thing to say is that in most cases the change in strength is not THAT drastic. The 3 top hands in all scenarios are still AA, KK, QQ. 72o is still a rubbish hand! In simple terms what happens is that in short-handed poker high cards become relatively more important and suitedness and connectedness decrease in importance.

The top 20 percent of hands, heads-up to a showdown are:

Some comments: All these percentages refer to a single opponent with a random hand – e.g. you are the small blind and everyone folds to you.

Note the high value of pocket pairs down to 8’s, especially compared to hands that are worth a raise from early position at a full table – like AK, AQ etc.

Note also that the policy of many players in such situations – ‘take an ace and race’ isn’t completely justified on the cards.

There is a fairly sharp fall-off with the size of the kicker, especially for off-suit hands - .e.g. A2s ranks at 48, while A2o ranks at 60 (i.e. not even in the top third of hands). Conversely two high cards with some co-ordination, like KTo rank well.

For the worst hands, note that low suited connectors count for little more than their off-suit counterparts. Also note that the traditional ‘worst hand in poker’ is not the worst hand heads-up, although it is still pretty awful!

A simple guide to help recall these hands, might work as follows:

Hand Ranks

‘Rules’

Top 10%

Pairs down to 6’s. Ace-Big (except ten), KQs

Top 20%

Add 5’s, Ax down to 5 suited and 8 off-suit, K-Big down to 9 suited and ten off-suit, QJs, QTs

Bottom 20%

No ten or higher in the hand, Any other cards where the sum of the cards MINUS their difference is less than 12 (off-suit) or 10 suited.*

* e.g. 96o has a sum of 15 and a difference of 3. 15 minus 3 is 12 so this just about escapes the bottom 20%

Adding one extra player changes some things. Our table for the top hands now becomes:

As we can see the values change slightly. The biggest ‘movers’ are pocket sevens which drop from 9 th to 15 th and sixes which drop from 17 th to 24 th with pocket fives dropping off our list, to 40 th place. AJo loses some value and AKs, AQs. A8o drops off the list while various other suited or connected (straights are now more likely to be a winning hand) hands move up – e.g. QJo and JTs.

One other thing worth mentioning is the ‘overlay’ i.e. by how much does our ‘equity’ against two random hands exceed our ‘baseline’ (if we held a random hand) ‘equity’. Note that the equity of the 34 th ranked hand is now 41.3/33.3 (i.e. 24%) rather than 59.5/50 (i.e. 19%).

What is happening is that in general as our numbers of opponents increases our strong hands become relatively stronger (although what constitutes a strong hand does change as we have seen) and our weak hands become weaker.

As for the weakest hands, there is less change in absolute ranking:

In a follow-on article I’ll look at how we can make use of this information in game situations.
