Betfair and pokertracker?

I have now solved the below problem thanks to Neb.

Anyone having problems with hands going into Pokertracker from Betfairs hand history? I have Hand History turned on in Betfair and plenty of hands get input but for some reason most of my all in winning hands are ignored with weird errors?

I have the latest version of Pokertracker. This is really annoying me =) I've had to fake some hands to make up for all the winnings ones it is ignoring.

Omaha Hand

I was playing heads up Omaha yesterday vs a very very very loose aggressive player. He was playing just over 90% of hands and raising over 40%. He had bluffed a lot and I was getting the better of him overall.

It is 3/6 Pot Limit Omaha, Villain is on the button and only completes the SB. He has $1636 and I have $1122 so we are both double stacked.

I have AAQ9 in the BB and raise to $18. He calls my raise making the pot size $36.

The flop comes 833.

I bet pot of $36. He instantly raises to $144 representing a three. This is the dilemma I guess now, I 100% know he would play any three like this but I also know 100% that he will bluff this board a HUGE amount of the time. So what to do? Call or fold are the only options. Folding feels too weak but I don't want to make a huge mistake for a double stack either. These are the spots I hate in Omaha, this is EASY in hold'em.

I decided to call making the pot $324.

The turn is the 7. I check.

He instantly pots for $324. He would clearly do this with any three and any bluff. Again my only option seems to be call or fold. But how to guage which is best when I know both are entirely possible. In hold'em this is a very easy call vs this type of player since players don't normally have a three in their hand and they have 50% less starting cards with which to hit a three. Also, no hold'em player ever plays 90%+ starting hands but this is fairly common in Omaha. I pretty much just gamble here and call. He can have a three, he can have a bluff and I'm not sure how to guage which is more likely. The pot is now $972.

The river comes the 8 giving us a board of 83378.

I check and he instantly pushes all in for $642. If he has an eight or three in his hand he now has me beat. Not a very good river card. I don't think we can look on it as a good card in as much as if he did have a three he wouldn't push on the river now the eight has hit because I think he would =). If he was not just pure bluffing on the turn and actually picked up a straight or heart draw then you can look on the 8 as a good card as he would see it as a very good card to bluff all in with. I was getting 2.5-1 pot odds so had to be right under 1/3 of the time.

I had come this far hoping he was bluffing and called the river fairly quickly. If he had showed me an eight here I would have been pretty pissed. I was prepared for a three =)

His hand was mucked and I won a $2256 pot. Omaha players please comment on this hand. In hold'em I know this check call situation vs this style of player is profitable 100%. I am entirely unsure in Omaha. It feels very close and perhaps even unprofitable. Shrug. Comments please. The other problem is it is low limits for me and I don't care enough about losing $1200, increase the limits by a factor of five or ten and I truly am in a dilemma.

Hand Analysis

Read yesterdays hand for more info on the following :-

I had to think for a while on this hand and was pretty close to folding but because I was only playing 3 tables of 25/50 I had time to go through the actions again one more time.

The key to this hand in my opinion is the turn play in two ways, first off, how often does he lead into the raiser then check the turn with a Set or AK when I have showed weakness by only calling on the flop? If it was me, a check here would be very rare from me as the chances of my opponent checking behind me and getting a free card are too high. I think this severely limits the chance of him having a set or AK on the river. Not completely but too a decent degree.

Secondly because I check behind on the turn, I have showed extreme weakness as I would probably never check AK or better here and he knows that too. He now knows on the river when I minimum raise him that I cannot possibly have AK or better. In other words I will have a somewhat tough decision if he pushes all in here. Which of course turns out to be true.

The other piece of information I had was that he pushed all in on the river fairly instantly. The only hands he can do this with are AK, any set and of course a bluff. I felt like he couldn't push all in instantly with A6 or A8. At least I could never do that, I would have to think for at least a small amount of time with A6 or A8 to decide what to do. It is not impossible of course, but in my opinion makes it less likely overall for him to have A6 or A8. So that narrows it down to a bluff, AK or Set but I had already reduced the chance of him having AK or a Set on the turn as I already spoke about above. Once I got to this stage in thinking I instantly called.

He had KQ and was indeed bluffing on the river giving me the $12079 pot.

I decided to put some ranges of hands into Pokerstove to analyse this hand further.

I gave for his winning range AK, 66, 88, A6o and suited, A8o and suited which is far too generous as like I said he would only play stuff like AK or set on the turn like this a small amount of the time, this assume he plays it 100% like that.

For his bluffing range I put in KQo, KQs, 79s and 79o which of course assumes he will 100% bluff with these hands but this is the part that is very hard to guage. I think this is a pretty fair range as I am not including anything like XX of clubs, 57, 79s, 9T, 45, KJ and lower, 6x, 8x and other random holdings.

When you evaluate with these holdings my equity is 53.8% and his is 46.1%. Which of course turns this into a clear call. In fact you can take out 79o completely and the equity changes to 40% and 60%. Which as I have slightly better than 3/2 still makes this a call. Anyway, it can't be as close to this in my opinion.

What does this show in this hand? It shows if my opponent is capable of bluffing AT ALL in this spot then I have a clear call as you only need a tiny range of bluffs to turn this into a profitable call. When you weigh it up vs the evidence presented before it shrinks his winning range substantially vs his bluffing range.

Of course saying all that some people are not capable of bluffing in this way EVER and you could never be profitable vs them so be wary with hero calls vs certain players.

$25/50 Hand, your comments?

Villain is 26.17VPIP and 20PFR, Aggro 1.5. I only have 300 hands on him and although it is currently 8 handed, 90% of my hands are from heads up or or 3 handed.

I have $13,282 in my stack and he has $5991.

All fold to me in the cutoff, I raise to $150 with A2.

The small blind calls, it is now heads up and there is $350 in the pot.

The flop comes K68.

He leads into me for $250, a case could be made for raising but I decided to just call here.

Pot is now $850 and the turn comes the 2.

I have a pair of twos and a flush draw. I could have as many 14 outs if he only has a pair. There are now two flush draws on board, one in clubs and one in spades. It is a total blank on the turn though and is very unlikely to have helped his hand.

He checks and I think for a bit. I check here which I think is fine because I felt he was calling 100% here with any pair. A big hand for him is unlikely as surely he would not check the turn with a set or 2 pair? A case could certainly be made for betting here which I sometimes would.

The river comes the A giving us a final board of K682A.

He bets fairly quickly $500. I must be good here 90% of the time so I know I must raise but what can he have? He seems like he could bet a King here but the Ace may also have now helped him if he led into me on the flop with Ace high. He could also be bluffing.

I decide to minimum raise and make it $500 more to him.

He very quickly pushes all in for his entire stack! Argh.

The pot is $7466 and I have $4616 more to call. I need to be right here well over 1/3 of the time.

What does he have? He could be bluffing with a large number of hands here I guess. Legitimate holdings for him could be A8 and A6 but these both have me beat. Would he really play these so hard on the river. Would he ever check the turn with a set or AK?

Call or Fold? How close do you think it is? Comments please!

Action tomorrow...

Welcome back Poker!

In the cut off with AK at RiggedoLogic. I raise to £40.

Button raises to £140. We have some small history over the past hour which suggests a push by me here will be extremely profitable vs his range. I push for £2539.

He quickly calls £909 more and I groan thinking I may be behind.

He flips over 97.

Flop comes 53Q.

Turn T.
River 9.

Total pot £2113.

He said he knew it was coming! I love Crypto. I think I'll deposit 20k more =)
