6max, commun spot but have questions about range building and game theory

Vilain opens in mp, hero flats in bb,
flop : Kc 5s Jc > hero x, vilain cb, hero calls
turn : Kc 5s Jc Qc > x-x
river : Kc 5s Jc Qc 3d

On the turn as vilain x-back, I think his range is quite capped. But as this turn improves a lot my range he mays x-back very often, including strong hands ? How you think he should build his range here ?

On the river the basic plan for hero is to bet (DP+ and bluff) and x-decide with the rest.

Some questions come to mind :

-How thin we want to value bet ? (as the turn improves us, we have not many «air hands» so vilain should not catch very light).

-Which sizing to use ? First, as vilain seems capped we want to bet big, but on the other hand as we have not many bluff, your range is «too strong » and maybe we should bet smaller ?

-To add bluff's combos, we can turn Jx (for exemple) into bluff and it will works well imo. But now for seek of reflexion following this logic to extreme, could we possibly sizing big (overbet) and bet your entire range here ? ^^

-In practice, we probably have a checking range here, as we want to bet our strong hands here, this checking range is weak and capped (showdown value hands) ... Is this a problem ? Should we defend 1-a on this spot (x-call vs vilain's bet), this question means basicly could vilain exploit us in this spot (when we check leaving us with a weak range). Or should we play more exploitive assuming : a) vilain will x-back most of the time (and we win on high frequency) AND b) vilain will bet basicly his rare strong hands and not realy bluff us... so we exploit-folding a lot

If you think some of the questions are interesting, feel free to share your thoughts on it ;)


(This is a CRev files to show I try to do my homework lol but I am not so good at this and it's not lead me to clear answer ..)

I think the worst hand we bet here is 53s/AK; KT seems really thin, but why not

-Which sizing to use ? First, as vilain seems capped we want to bet big, but on the other hand as we have not many bluff, your range is «too strong » and maybe we should bet smaller ?
i think we can bet 3/4 with a lot of our range; betting 40-50% with our bluffs could be nice seems we represent Kx or even AQ

-To add bluff's combos, we can turn Jx (for exemple) into bluff and it will works well imo. But now for seek of reflexion following this logic to extreme, could we possibly sizing big (overbet) and bet your entire range here ? ^^
yeah Jx will not win a lot at SD;
we can overbet this spot: we have AT T9 and the best hand for vilain is Kx Qx
maybe not our entire range but overbet Jx and worse and QJ or better seems nice

Thanks for answer.

  • I dont think we can value bet very thin here because our range contains a lot of clear value and not so much bluffing hands

  • About of sizing, assuming vilain is capped (again I am not sure he should ?? ) whatever sizing does "ok". But what is the best sizing in such situation ? I mean if we were polarised, betting big and do it with the majority of our range is the clear answer. Here, we are not pola, our range is composed of nuts/strong hands (flush, str8, set), made hands that we can possibly v-bet (DP, good tp), and weak holding (sd-value hands and few air) : how to build our betting range theory-speaking ?

  • Also when in a given spot our betting range is "too strong" (not enough bluffing combos whatever sizing we use) : is it better to bet very small pushing vilain to react (calling or raising wrongly because he should just fold) or bet big hoping he calls from time to time ...

  • The last part is a general question I think, in some area of our game plan we leave us with a weak checking range because of another action (for exemple here we will bet nearly all our strong hands). This weak range is exploitable in "a vaccum" but I am not sure vilain can always possibly exploit it because of the low-frequency of the spot and/or because of vilain's range (not enough combos to exploit us). That is the idea but if some GTO-guys can put some logical thoughts and numbers on it, will be very helpfull to recognize when we should defend a range and when we don't really care ...

Bluff 5x and spades, value bet kx+ sometimes, sometimes x. Xr quite often. Some over bets are def fine

Thanks for your answer Ben, I can see that the "solution" (as often) is in a mix strategy and the good use of it ... (mix strategy and frequencies associed are tricky for human's brain imo ^^). I will use your advice and play a little with CREV to see how we can articulate that :)

Why xr verry often makes sense? Dont we expect villian to check back river a lot of we have a xr range on river?

I try find an answer. think the EV of xr value on river is higher than betting. I think the hands he will call our river lead with, are also betting often if we check( AA/AK).
