DSL Fish Profile Notes

Question 1

Do fish have positional awareness?

Specifically, do fish change amount the bluff on river with mid-pair and lower going from BTN to EP?

Answer 1

No correlation (hovers betwen 25% and 35%)

Can eliminate position when thinking about fish stats.

Question 2

Do regs have positional awareness?

Specifically, do regs change amount the bluff on river with mid-pair and lower going from BTN to EP?

Answer 2

Yes, they bluff less in earlier positions (falls from 31 to 21 from BTN to EP) (from tightening of preflop ranges with less blufs)

Question 3

Is a fish’s range composition dramatically affected by bet size?

Answer 3

Yes.

Question 4

Are overbets and size ups between 0.8-1.0pot from fish underbluffed, balance, or overbluffed in a B-B-B line?

Answer 4

Underbluffed and rare.

Question 5

Are 0.6-0.8pot from fish bets overbluffed, balanced, or underbluffed in a B-B-B line?

Answer 5

Overbluffed. Call with any mid pair.

Question 6

Are 0.4-0.6pot from fish overbluffed, balanced, or underbluffed in a B-B-B line?

Answer 6

Balanced. Profitably call with any top pair.

Question 7

Do fish lack texture/range awareness?

Do they call more or fold more on:
a) highly interactive textures
b) non-interacting textures

Answer 7

They do not have range awareness to recognize bad runouts or “scare cards” for preflop caller.

Only look at basic texture interactivity

a) fish fold slightly more on highly interactive textures
b) fish fold slightly more on non-interactive textures.

Overall, calling requirements consistent across textures.

Question 8

Are Stop-and-Go lines (e.g. villain goes B-X-B, or XC-X-B) overbluffed or underbluffed by fish?

Answer 8

Fish dramatically overbluff the B-X-B line for all sizings except overbet which remains balanced.
Fish dramatically overbluff the XC-X-B line for all sizings except overbet which is underbluffed.

In many cases we should have profitable CALL WITH ANY PAIR
(texture shows little correlation to river range composition)

Question 9

Is B-X-B from fish villain overbluffed or underbluffed?

Answer 9

Overbluffed dramatically except balanced overbet.

CALL w/ ANY PAIR

Question 10

Is XC-X-B from fish villain overbluffed or underbluffed?

Answer 10

Overbluffed dramatically.
Especially on Low runouts (massively overbluffed)

CALL w/ ANY PAIR

fish bluff even more more after 1/3 cbet, so keep in mind in close decisions against XC-X-B line.

Question 11

Flop check raise from fish, which sizes are overbluffed or underbluffed?

Answer 11

0.4-0.6pot is overbluffed, but is balanced or underbluffed for all other sizings.

Call w/ ANY TOP PAIR against this1/2pot sizing,
Increase calling requirements to strong top pair or two pair vs other sizes.

Note: This is exception to rule that 0.6-0.8 sizings are most heavily bluffed.

3-street agression lines where fish is OOP where fish is OOP, smaller sizings tend to be bluffed more.

Question 12

Fish turn check raise followed by river bet is underbluffed or overbluffed?

Do we call with top pair?

Answer 12

Fish turn check raise followed by river bet is significantly underbluffed by fish.

CONFIDENTLY FOLD ALL TOP PAIR in almost all cases when facing a bet on the river. begin calling with medium strength two pairs

fish bluff w/ significantly fewer missed draws in both flop and turn XR lines compared to regs (who overbluff).

Question 13

Do fish bluff w/ significantly more or fewer missed draws in flop and turn XR lines?

Answer 13

fish bluff w/ significantly fewer missed draws in both flop and turn XR lines compared to regs (who overbluff).

CONFIDENTLY FOLD ALL TOP PAIR in almost all cases when facing a bet on the river. begin calling with medium strength two pairs

Question 14

Fish river check raise: underbluffed or overbluffed?

What is bottom of calling range against it?

Answer 14

SEVERELY underbluffed. 23% underbluffed for overall, 17% for minraise.

Call strong two pair or better.

Counterintuitively, min raise sizing even more underbluffed than other sizings. TRIPS AND SETS bottom of calling range against minraise

Question 15

Fish river min-checkraise: underbluffed or overbluffed?

What is bottom of calling range against it?

Answer 15

SEVERELY UNDERBLUFFED. 23% underbluffed for overall, 17% for minraise.

Counterintuitively, min raise sizing even more underbluffed than other sizings. TRIPS AND SETS bottom of calling range against minraise.

Question 16

In position river raise from fish, underbluffed or overbluffed?

Answer 16

River raise in position is severely underbluffed by fish.

Like river check raise, call with strong two pair or better.

Question 17

Is in position raise X-R-B line from PFC fish overbluffed or underbluffed?

Answer 17

Also severely underbluffed by fish.

Profitably call with ANY TOP PAIR on the river vs this line.

Question 18

Donk line from fish is significantly underbluffed or overbluffed by fish?

Do we fold top pair on river after villain OOP as PFC?

Answer 18

Donk line is well-know volatile line significantly OVERBLUFFED by fish. Similar stats for turn and flop donks.

Do not fold top pair on river unless fish sizes up.

Can call any top pair vs 0.6-0.8 sizings
Can call mid pair against smaller sizings.

Question 19

Vs fish 3bet triple barrels.

How similar are MDA conclusions for playing against fish in 3BP vs in SRP?

When facing a triple barrel in 3bet pots against fish, do we fold top pair?

Answer 19

RARELY FOLD TOP PAIR against 3bet triple barrels unless fish sizes up.
Similar conclusions for 3bet pots as single raised pots in all lines.

Question 20

vs fish 3bet stop and go lines:

Are fish massively overbluffing or underbluffing in stop&go lines (B-X-B or XC-X-B) in 3bet pots?

Answer 20

MASSIVELY OVERBLUFFING

Generally call with mid pair+ unless fish sizes up.

Question 21

Are fish as in-position defender in 3bet pots overbluffing or underbluffing as in-position?

What do we call against them as result? How about for the much larger sizings?

Answer 21

Fish are SEVERELY OVERBLUFFING in all common lines as in-position defender. (villain C-X-B, C-C-B, C-B-B as IP defender)

We should call with any mid pair in general.

against larger sizings, increase calling requirements to strong top pair vs oveberbets and size ups.

Question 22

Do fish generally bluff more or less as preflop caller?

Answer 22

Likely due to widened ranges from just calling vs raising from fish.

Exception is XC-XB line of course.

Question 23

What are most important data points of the following with regards to bluffing against fish?

Texture, Formation, Bet Size, Line

Answer 23

Bet size and line are most important

Question 24

In general, underbluffed patterns from fish include?

Answer 24

Overbets/Size ups
Turn XR
Any River Raise

They they overbluff most other lines (especially stop&go)

Question 25

In general, for normal and small sizes, what lines do fish overbluff?

Answer 25

Almost all lines EXCEPT overbets, turn XR, or any river raise.

Stop&go are especially overbluffed.
