Question 1

Flop vs reg PF AGG

Answer 1

• C-bet flop entire range, 1/4-1/3 pot. Favor the smaller option when you sense SPR is a bit lower than usual. Either because the pot is inflated due to having to 4-bet against a larger 3-bet sizing, there was a squeeze multi-way, or villain was slightly short-stacked.
• Exception: Favor checking back broadway pair value (especially premium value where denying realization is not as important) to soften villain’s range and allow them to bluff turn. Low boards can be c-bet because we value realization denial a bit more, and most importantly villain floats wider and will reopen in C-X-B line as a bluff too frequently. We can also profitably call any pair on most low boards vs XR, so c-betting is quite safe.

  Key note: the XC-X-B line is over-bluffed for virtually all sizings but trending more balanced as it approaches PSB/over-bet. We should rarely be folding pairs in this line unless there is extremely high interactivity. On less interactive boards we can begin calling with AQ+.

Question 2

Flop PF DEF

Answer 2

Facing X from OOP aggressor: Stab 1/3 pot with all bluffs. Check all value. This is a highly exploitative vacuum approach that takes advantage of villains over-fold after missed c-bet and his tendency to over-bluff future streets. 4-bet pots are the best spots to use super exploitative strategies because they’ll have the highest resilience (they occur much less often than other zones).

Question 3

Turn PF IP AGG

Answer 3

1/3-1/3-1/2 pot is the the dominant sequence and we will be playing all of our bluffs in this way. This sizing scheme is roughly what you should expect with 100bb effective starting stacks. If you find yourself with more or less left behind on the river, make sure to still play the bluff (just go all-in). All sizings are clear hotspots in this line on all streets. We don’t have sample size for really deep effective stacks, so just use 1/2+ with bluffs (over-bet if you wish).

Question 4

Turn PF OOP AGG

Answer 4

Bet 1/3 pot, this funnels villain into another significant 1/2 pot river hotspot. We’ve explored some large sizing hotspots (like jamming for 1.5x+ OTT), but the pool doesn’t raise turn enough to incentivize this over the 3-street sequence, which gives us the bonus of 2 streets of substantial hotspots (turn and river), instead of just turn.

Question 5

Defender profiles

Answer 5

• Facing B-B is underbluffed.
• Facing B-B-B is under-bluffed
• Facing B-X-B is under-bluffed.

Question 6

River PF AGG

Answer 6

• XC-XC-XF is over-folded by OOP defender more than IP defender, for both regs and fish. That said, it’s still a big hotspot regardless of positional dynamic.
• 1/3-1/3-1/2 pot sequence nets 30% of the pot share on the river hotspot! That’s almost double the worth of the OOP hotspot.
