Toiling in the Dark - Part 1

It's a nice and sunny June Friday in Seattle as my wife Tali and I make our way to the airport from our home town of Issaquah, 18 miles away. Our Lyft driver is interested in our destination and in response to "Vegas", a discussion of its current heat wave ensues. Ironic, I think, as I've been long yearning to escape our seemingly endless pseudo-spring with its grey and damp climate, only to fall into a boiling furnace.

The airport is the usual summer zoo of manic families and confused elderly travelers, mulling around in disorderly fashion and clogging the concourses. Even at the TSA precheck security line, people seem clueless about what they should be removing. I remark to Tali that the Vegas crowd should be especially merry and repulsive today.

After a quick lounge visit (courtesy of an expensive AMEX Platinum card membership), we proceed to the gate and hear an agent summon us to the desk. There is a pleasant young couple, seated separately in our row, and we are asked to agree to seat changes to accommodate them. Sure, we say, as long as we sit together. So the changes are made. As I eye the male, something tells me we are headed to the same event (more on that next).

In flight, as I get up to the toilet, Tali and the girl from above-mentioned couple, chat and figure out that both their husbands are going to play poker at the WSOP. As i return, she says he's playing a "deepstack" and I say, cool, I'm playing "monster stack". Aha, she says, I think that's it. Eric, is that the event you're playing? The response is affirmative. A chat ensues, whereby I identify a fellow weekend warrior type who wants to take a shot at luck. To the unfamiliar, our event is a $1,500 buyin multi-day poker tournament, attracting over 6,000 entrants with a first prize of over $1M. Even a "small" five-figure cash for a top 100 finish would do wonders for my poker bankroll, allowing me to venture into larger cash games on a regular basis, really the primary purpose of this trip.

Vegas more than fulfills the promise of its heat wave, and luckily I stop by the Starbucks stand for a Venti Ice Coffee before venturing out to the scorching 115 degree pavement. 
We stand for 10 minutes in the inferno until a rental car shuttle arrives for the very long drive to the rental car center. One wonders whether Vegas's town elders had cleverly planned this center to be particularly distant, for the indirect benefit of its taxi and limo operators.

We stay at an offsite Marriott in the convention center area. This is predicated on the idea to relax away from the crowds when not playing poker. Tali, ever supportive, had agreed to come along for a couple of nights and we thus end up in a decent suite. After arrival, our errands include shopping for in-room groceries and signing up for the Sunday flight of the Monster Stack at the Rio casino. Completing those two errands consumes our entire afternoon. Getting around in Vegas these days is a time consuming affair, with the long red-light waits even off strip, and locating a decent grocery store in the vicinity is not an easy endeavor. Healthy living is apparently not the mainstay of this town.

For dinner, we decide to go to the Fremont area of downtown, where new and affordable eateries have been popping up as an alternative to the over-priced and hyped "strip" casino dining venues. On Google maps, I locate Carson Kitchen, a small chef restaurant with modern American cuisine offerings. It doesn't take reservations, and upon arrival at approx. 7:30 pm we are given a 40 minute wait time, or an alternative of hanging out at the roof patio bar until spots free up. We happily take the bar option and enjoyed cocktails there, albeit the 8 pm temp is still 108 degrees and the bartenders are distinctly unhappy; one of them remarks that this seemed a good idea in April.  

Once seated, the meal itself is impressive. Not a bona fide foodie, I won't go into details of the menu but recommend that the interested inspect their website's menu. However, seated on a common table, there is a group of people to our side and opposite Tali, amongst them a lady whom she claims is giving us the "evil eye". A bad omen for poker, I thought. At some point, Tali stares back at the lady and fake-smiles her into oblivion so that she would stop her evil-eye business.

Saturday passes in non-poker activities, which well suits my plans. Relaxation from a hard work week in the East Coast includes heading out to the Orleans cinema to watch the silly (and fun) Wonder woman film. The cinema itself is one of these newly tricked out sofa-style venues, and while the crowd enjoys it, they still think that attending a cinema gives them the inalienable right to leave their crap strewn around the place when they leave.

Sunday, the big day. I awake at 8 AM and head to the gym, preparing physically and mentally for a 10 to 12 hour day of intensive poker play (assuming I survive it). Then, at 9:15 I head out to the Rio on my own, Tali planning to depart for home later that day. I arrive and suck in the WSOP atmosphere - hundreds of players in the hallways, many (like myself) with backpacks. Loud conversations of bad beats and failed bluffs reach my ears, as I make my way to the Amazon room, where play will commence at 10 AM. No major celebrity sightings though, unlike last year when I had sighted luminaries like Seidel and Galfond in the hallway (Seidel being even taller and thinner than I imagined).

I am the first to arrive at the table, and as people start filing in, I try to see if I recognize known players, but none come the way of my table. I had played this event in 2015, and survived to Day 2 only to bust with a short stack. This time, I resolved to "open up" my game somewhat and be less tight-passive.

The structure of Monster stack is pretty deep and slow. Players get 15,000 chips and play starts at 25/50, with 300 BB. Levels are one hour, allowing patient players the opportunity to be selective in their game and the impatient ones, the opportunity to steal small pots and/or punt off their stacks early on. I belong to the patient category, with deviations as seen appropriate.

As play starts, I am happy to see no famous (or infamous) pros at my table and by play styles, I conclude that this is going to be a passive group, at least for the first few levels when nobody wants to bust early.

My first hand played, I am quietly proud of, using a particular board runout to my advantage.
At 25/50, 15,000 stacks, the cutoff, Button and small blind all limp to me in the big blind. 
I look down at 75cc and check.
The flop is K86 rainbow (pot size: 200)
It goes check/check/150/fold/call/fold (I am the caller). (pot size: 500)
The turn is a 3.
I bet 250, Villian raises to 600 and I call. (pot size: 1700)
River is an Ad with no possible flushes. 
I bet 1000 and Villian folds. 
I have just executed a nice bluff, leveraging a "scary" river card to represent a winning hand when my flush draw misses.

Play continues on and I am able to play 3-4 hands at this level.
At the second level (50/100), I play a hand out of position with AQ and am forced to fold when the runout is low cards and a J appears on the turn. 

My stack is at 15,700 when this key hand unfolds:
I am UTG with 77 and bet 300.
A seemingly tight passive lady in the CO position raises to 600. The button, having doubled up in a prior spot is on a bathroom break, and so she is the effective button. The blinds fold and I call.
The flop is A75 rainbow. (pot size: 1350)
I check, she bets 600. I debate whether to raise or just call with my flopped set, and decide to try and extract more value from this hand by calling and keeping her in with weak Aces and lower pairs.
The turn is a Q (pot size: 2550).
Check, she bets 1500. Everything is proceeding according to plan, and I call. As well, in case I am behind QQ and AA, I don't want to stack off at this early stage.
The river is a 3 (pot size: 5550).
I check, she bets 1500 and I 3bet to 3500, wanting more from my set but not really putting stacks in play. She calls and I open my hand. To my amazement and disappointment, she shows QQ! Wow, I think, I've just dodged a bullet.

*** August 2022 edit: this hand needs to be re-analyzed. ***

Preflop
: CO's 3Bet sizing of 600 is terrible and typical of tight-passive players not knowing what to do with premiums. To me, it should scream strength and my just-call is mandatory.

Flop
: On the A75 flop, the rationale of "calling and keeping her in with weak Aces and lower pairs" is typical of 2017 pre-solver thinking, and not very good thinking at that. I think Jonathan Little was my main tournament influencer at that point (boo!!). It's actually counter to our incentives. My incentive having flopped middle set is to get stacks in by the river. CO being tight-passive, is not going to get me there on her own. Opening with a check is what I will do with 100% of my range, but when she bets, I need to get a check-raise in. Granted, my CR value range is very narrow (A7 suited, A5 suited, 77, 55) and I never have AA in my preflop open/calling range. Also note that this player type will almost always lay down the QQ in the face of that 3Bet and I would have won the pot; proving that even a hand as strong as a middle set still wants some equity denial.


Turn: As played with the flop check/call, I should still C/R here. Whether or not to stack off can be a decision point if she jams - and with her passivity she's only jamming nutted hands, perhaps not even AQ.

River: Springing the river 3Bet was fine, but it should have been larger for value extraction from AK, AQ. 


GTO+ Solver output: 
Iteration 1: playing at equilibrium with no node locking.
Working with a modified UTG open/call small 3B range of 8.75% (116 combos) and a tight button 3B range of 3.85% or 51 combos:

Flop
: I (being OOP) check flop 93% (effectively all the time). She (IP) bets only 50% of the time and with QQ she mostly checks. If she does bet, given two sizing choices of 45% pot and 75% pot she will opt for the smaller size that she did.
When she bets 600, I mostly raise with 77, to 2150 and she folds. I do have a 42% calling range though.

Turn: When I call flop as played: 
On the Q turn, I check my entire range. With her QQ she is betting a larger sizing of 1900 80% of the time and checking the rest of the time (I also gave her the 1500 option).
When she bets, I just call with 77.

River: On the river, I check, she bets large (4800 not 1500) and I fold.

Conclusion: The solver never takes the line that my opponent did. With a set of QQ, it bets larger on both turn and river. Given the extreme tightness of her preflop 3B range, it has me folding a hand as strong as 77 to a large-ish (80% pot) river bet.

Iteration 2: playing with opponent node locking.
This iteration is tailored to exploit my opponent's passive tendencies. In the original run, my EV (expected value) with 77 on this flop is 2272, with a pot of 1350. It's pretty rare to have an EV much larger than the pot size! 

A flop node-lock representing tight-passive behavior looks something like:
- Bet 1000 with AA, AK, AQ.
- Bet 600 with KK, QQ.
- Check back with JJ, TT.

Running the solver with these settings, yields me a flop EV of 4558. That's a ridiculously large one, due to opponent's poor play.
In this configuration, I check/raise the flop to 2100 100% of the time. 
The solver now has her calling half the time with KK, QQ (the only hands that bet 600). Now I instead node locked her into a fold in this spot. 
Now my flop EV goes to 3715 - still very high, but somewhat lower than the first node-lock only, because when she folds KK-QQ 100% to my flop C/R, I lose some expected value.

Conclusion: Against a tight-passive fish, the flop is a mandatory check-raise on my part. I should be stacking off against AA and winning a nice pot against everything else.

*** End August 2022 edit ***

At this point, I'm left with 9500 chips or 95 BBs. Still lots of play! But I have a premonition that things are not going to go well for me on this day.

At the next level, blinds are 75/150, antes 25. I am able to work my stack up to 11,000 when this hand occurrs. This (I think) is my major misstep (the 77 vs QQ loss considered to be a cooler, not misstep).

I pick up AhQc in the cutoff and bet 400. The player to my left, a competent (possible pro) 30-ish guy, calls on the button and the blinds fold.
The flop is 954 with one heart (pot size: 1275 with antes, we are 10 handed)
I check, he bets 700, I decide to call. My plan is to win with any A, Q and to bluff any K, J, perhaps T that hit a later street.
Turn is a 3h. (Pot size: 2675)
Check/ 1500 / call with the same plan. This is an optimistic call, since I may now be drawing dead against hands like 76, A2, sets of 44, 55, 99.
River is a 6d. (pot size: 5675)
I look at the board for a few seconds and decide that it's scary enough to bluff. I lead out for 2000. This mimics a value hand that I might be betting a hand like TT+ with. He thinks for a bit, murmurs to himself, and ends up calling, showing 98 offsuit.

I conclude my bluff may have been well timed, but surely too small. if I had made it 4000+, Villian would have been hard pressed to call. I had targeted the correct player type, an observant and balanced type, definitely not a calling station fish. In retrospect, a turn lead or c/r repping A2xx or 76xx would also have been sweet.

After this hand, I am left with 6400 chips and while still viable with over 30 BB, in jeopardy and hamstrung compared to my opponents. From this point onward, I cannot play implicit odds type hands effectively, since I am not getting correct pot odds. I am limited to finding value with large pairs, broadway cards and the occasional "blind special" hand that people will limp into when I am in the blinds with a weak holding that happens to flop well. 

Another hand that plays out to the river, I hold TT and fold a low card board with a Jack on the river, when there is a shove, and a player behind me who ends up calling. The winner shows JJ and I am "saved" again.

But clearly, this is not my day. I am on the wrong side of almost every significant pot and, in the over-used parlance of poker pros, can't get anything going.

I nurse my short stack until the middle of the 5th level and head back to my room in mid-afternoon with a pulsating headache and heartache. I decide to take a rest, get refreshed, and get back into the fighting pits the next day for another event. More on that in my next post!
