6-max blind defense

[GME]

D5, this completely rocks. Thanks for posting it. I have appended this to MEBenhoe's original chart on the right-hand side. I've also formatted it to print on one page and changed the colors to look OK on a black and white printer. If anyone is interested and can tell me how to post the file here, let me know.

Why do we need 40% equity if we're gettng 3.5:1?

40% is not necessarily the correct number, but I believe it's pretty close. I could have sworn I saw it referenced in the AQ test but I can't find it now so I can't use that argument. [img]/images/graemlins/smile.gif[/img]

Essentially the problem here is if you are going in as too much of an underdog with a hand like T7s (a 35% equity hand) you are going to be hitting a lot of second/third pairs and will throw away a lot of money. 1/6 of the time an ace flops and you will often have to throw your hand away (even if you hit a T or a 7).

You'll be out of position for the entire hand and nearly 2/3 of the time you will miss the flop completely and basically have to check/fold throwing away 1BB more than you had to.

Throwing away a hand like T8 on a ATx flop seems a little weak and bad play, in general. T7 against the assumed range of stealing hands pre-flop on that flop is a 55/45 dog, and you are risking 2.5 BB to win 7 BB, which means you would have to have at least 35% of a chance to make some sort of profit. Of course, if your opponent is predictable (ie: will not raise this flop w/o a hand that beats second pair, [censored] kicker) then you can dump it for less.

(However, your equity is much greater on a KTx flop (~60%) than a ATx flop, for obvious reasons).

I'd be interested in seeing this in table format. Couple points I'd be interested in knowing:

- Is this valid only against a button raise (ie defending with 40% equity hands)? How bout HU vs CO, UTG+2, etc? Obviously need to tighten up here but how much?

- Need to continue the SB defense conversation and at least start with some hand ranges as d5 has done here.

And d5, thanks for the cool post!

First off you are absolutely correct that you have a great hand on a king high flop if you hit a T.

As far as the ace high flop, when you are way behind, you will lose 2.5BB more (3BB total). This is nearly half the time (around 15.8%/34.5% you are against Ax/AA/TT/22 (using 2 as the x on the ATx flop)).

6.5%/34.5% You will be against KK/QQ/JJ/KTo/QTo/JTo/KTs/QTs/JTs/T9s/T8s/T9o. If the opponent will check behind on the river you'll only lose 1.5BB more (2BB total). If the opponent will value bet the river you'll lose 3BB here.

The rest of the time (11.9%/34.5%) you are against 99-33 (not including 22, the other set on the flop)/KQs/KJs/K9s/K8s/QJs/Q9s/Q8s/J9s/J8s/98s/87s/KQo/KJo/K9o/QJo/Q9o/J9o. At best you will get 1.5BB out of these hands which completely miss (and many players would check behind on the turn and fold the river with these). So you'd win 7.5BB here (2BB which you put in voluntarily, so 5.5 profit).

I think your best EV looks like:

-15.8/34.5*3
-6.5/34.5*2
+11.9/34.5*5.5

= .1475.

So it could potentially be a positive situation. But many opponents would value bet KK/QQ/JJ/Tx on the river and most would be capable of folding something like 98s/87s/J8s/J9s/J9o/Q9o/Q8s/Q9s/QJs when it didn't improve (we'll even assume he'll call a river bet after checking behind on the turn or bet the turn and check behind on the river with 99-33/any king).

-15.8/34.5*3
-6.5/34.5*3
7.1/34.5*5.5
4.8/34.5*4.5

=-.181

Still against most players it would probably be ok to call down here.

New chart hosted here.

Looking at this chart it becomes rather obvious, that this is a pretty predictable strategy. If our hero is calling from the blinds, you always know that he doesn't have a premium hand.

Too bad Abdul Jalib isn't here anymore to provide more insight on pre-flop ballancing.

[MrWookie]

Balancing is all well and good - IF you're going to be playing a lot with the same players. Given the high turnover of low stakes online play, though, making the theoretically most +EV play in a vacuum is virtually always, well, the theoretically most +EV play.
