Lesson 5 Flashcards
Are there significant differences between playing in position and oop?
I can look at it as if it’s a completely different game with a different set of rules(!).
There’s a lot of tricky, trappy, play in theory. You’re the snake in the grass, and allowed to be less obvious when it comes to your value hands.
SRP SB vs BB, flop A94 sds X/X
turn comes 8s
What bet sizes will the sb utilize and why?
Since the turn is both polarizes the board and favors BB’s range, sb can only bet small (B33) or X.
SRP SB vs BB, flop A94 sds X/X
turn comes 8s
For each of the following hands, is it a mistake to check again the turn oop?
- J8ss
2.88
3.KhQs
4.QhTd
- Not a mistake - a flush blocks BB’s continue range, the 9 blocks his continue range as well, so solver actually checks most of the time here so BB can maybe bluff with his Q6hh.
- See 1.
- This hand has tons of equity and is a middling hand - why would I bet it? It’s a mistake to bet it.
- This is a frail hand - so checking IS a mistake
What are polarizing blockers?
For example on A948 if I have 99 or 88 I block his 9x and 8x so I block villain’s middling hands, therefore I polarize his range
What’s the concept of urgency?
a value candidate hand has urgency, when it would experience a theoretical ev loss if it checked instead of betting, or if it bet small instead of betting big
What are the factors that determine urgency?
1.SPR - if it’s a small SPR there’s little urgency since it’s easy to get the stacks in (for example, 3b/4b pots)
- Position - When I’m OOP I can check-raise so urgency again goes down (there’s more time in this street / more nodes in the tree).
What is a mixed-polorised strategy?
While we bet for value sometimes good hands, we’re also mixing them between betting and checking.
What is the river blocker theorem?
It applies OOP only:
Favor betting when holding value hands which unblock villain continue range (medium range) and block villian’s bet range if I check (good and bad stuff).
Holding such cards will condense villian’s range and decrease his betting frequency, but increase his calling frequency.
Favor checking when holding value which block his middling range, and unblock his polarised range(good and bad stuff).
Texture is K7Q83,sb vs BB, action was B/C,XX, and now sb can bet.
What does the river blocker theorem say about the following hand:
77
This polorises villian’s range (into having Kx or Qx or air) which can bet, so it’s fine to mostly slowplay
Texture is K7Q83,sb vs BB, action was B/C,XX, and now sb can bet.
What does the river blocker theorem say about the following hand:
KK
This hand blocks top of villian’s range, so it mostly bets
Texture is K7Q83r ,sb vs BB, action was B/C,XX, and now sb can bet.
What does the river blocker theorem say about the following hand:
QJhh
This hand blocks some bluffs (JT) so it mostly bets. It is strong enough to bet blind vs blind (for a small sizing) despite it being only second pair.
In other words, fast play when blocking bluffs.
What are the 3 types of slow playing?
- Theoretically approved slowplaying (can value bet, doesn’t suffer ev loss in theory)
- Exploitative slow playing
Hero accepts the theoretical ev loss because he thinks that in the real world, checking will yield more ev - erroneous slow playing
It’s an EV loss both in theory in the real world to slow play, and hero has no sound reason to deviate.
Which type of slowplaying is the following:
I def A9o with As as BB vs BU,
K64sss flop X/X,Jd turn X/X,5s river and i check for the third time
In theory, this might be ok to slowplay “Theoretically sounds slowplay”. I can check-raise this.
Which type of slowplaying is the following:
I open QTo no spade as sb, a passive fish calls, Q53 two spades x/x,Ah turn x/x,6s river x.
The fish will never bet by himself a worse hand, so it’s not ok in practice.
In theory a strong Qx bets small here, Th blocks his bluff range (air?) so it’s 100% bet in theory.
So this is an erroneous slow-playing
Which type of slowplaying is the following:
sb vs bb, I open J9cc, agrofish calls the BB.
flop JJ3r X/X,
turn 7h X/X,
river 6s X
It’s an exploitative slowplay - I expect an aggro whale to bet the river a lot. This is probably not a theoretical sound check on the river but in the real world, it will produce more EV.
Notice that the 9 is a condensing blocker, so that’s why in theory it’s never a check(!). But this is only one brick in the wall, of course, only ever so slightly changing villain’s range, the fact that villain is aggro fish is 10000000 more important
