Hello Mati,

I am playing lower limits, but if you don't mind I would like to say a few words about your hand.

• preflop it's a standard
• I am considering his range now. You are playing a 4-max so he should 4bet you with a higher than normal frequency and wider than on 6-max.
• you didn't write anything about his stats or any more info so I assume that he is an unk reg (quite aggressive for me means little bit over average, so it's still an unknown player)
• I assume that unk reg won't normally slowplay here and when he is calling you then his range is capped because normally he would 4bet with AA-TT, AK, AQs
• however, everything change when we look at stacks here. You are around 170bb deep and people on deeps like to flat more often to make a trap. The point is that he could have more monsters in his flatting range than normal
• on the flop your cbet is a standard and now you are getting a raise
• now the board is action-heavy and you have a bottom two pairs. You are blocking 88 and 77, so the question is how to react
• normally people should 4bet JJ CO vs BU, so I wouldn't be worried about that. Would he play like that T9s? It's only 4 combos. Would he x/r here with a good flush draws? certainly. Would he x/r here with AA/KK is he was scared preflop? definitely. We can't forget that you are playing 4-max, so he can x/r here with some bluffs as well, maybe Jx.
• on 100bb I would consider shoving here, but because you are deep that's not an option and you have to call
• turn is blank and now you have to decide what you are doing, because opp is just saying that he is shoving on the river.
• I know how it feels when only 9 combos can beat you, and 2 of them are very unlikely due to your blockers, 3 of them are unlikely because this combo should be in his 4betting range
• However, imo people in deepstack pots are more sincere than normal and now let's think about what other good combos he can play like that - x/r flop and bet blank turn.
• let's give him first AhJh, KhJh, QhJh, JhTh. We have 4 combos now. He may have something like AhKh or AhQh occasionally, but normally he would probably 4bet you or x/c flop. He may have other flushdraws, including AhXx (but again he would probably just x/c flop with them) and other broadways. From this range combos which could play like that, I will pick QhTh, AhTh and Ah9h. So we found 7 combos. Maybe even 6h5h, but let's be tight.
• so now let's assume that he only semi-bluffs here. IMO that's not so good assumption, because players could play like that good backdoors for example, but let's just do it because I want to show you that you have a call here
• so 9 combos beats you and you are ahead of 7 combos. With 2 combos you have a split.
• if we assume that he might slowplay AA sometimes and rarely KK and if we assume that JJ might be in his 4bet range sometimes, then for me you shouldn't fold here
• now the question is do you have to call or do you have to raise here
• when you jam here, he will fold from above range: AA/KK/bluffs. He should call with his flushdraws because he only needs here around 30% equity against a set and after your shove he will have 25% odds to call (42 to call and pot is around 125 after your shove, so 42/(125+42))
• he won't fold any better hand than yours which means that you have to call and I wouldn't jam here because there is more cons than pros
• on the river you have a sick spot, but now you are getting very good odds here. If he is playing like that a busted flushdraw from time to time and if he is really slowplaying here AA or KK sometimes, then you cannot fold here
• for me, well played cooler

I hope this answer helps you.

Preflop, I think when 180BB deep, it's fine to flat JJ vs BTN 3-bet (at least some of the time). So I think he can have JJ here.

His flop check-raise indicates a polarized range. So he probably has a set, T9s, two pair or a semi-bluff. Pair+FD and top-pair type hands would probably not take this line. He might also do this with an overpair, though QQ-AA is likely to 4-bet preflop.

You block the two pairs and most of the sets and unblock hearts. So his value range is something like: JdJh, JdJc, JhJc, 8s8c, 7s7c, T9s, 8s7s, 8c7c
which is 11 combos.

His bluffs are something like: KhQh, AhJh, KhJh, QhJh, AhTh, KhTh, QhTh, JhTh, Ah9h, Qh9h, Jh9h, Ah6h, Ah5h, 6h5h, Ah4h, Ah3h, Ah2h
which is 17 combos. However, he might not have all the combos preflop all the time, and not all of them will take this line. Nut flush draws will often check-call flop, though they could check-raise too.

It's a decent hand to call down with, but it's close.

One other thing to keep in mind is that when people play deep like this, they tend to bluff less. (This is one reason why I don't like to play this deep.)

My thought process in game on river was quite clear: all drows miss, I am on the top of my range, I blocking his value range and I unblocking potentional bluffs, but...,I still have to consider that we are deep a people play more honestly in this spots and on lower stakes overfolding in some situations is not a mistake...

So what? I think river decisions is quite close, that mean call is not a big mistake, but fold is probably a bit better.

How wide are you 3 betting here preflop this deep? I would expect his calling range to be slightly wider here due to stack depth. At this depth, I start to lose some of the middling connectors and add in more combos of Axs (most specifically A2s-A5s, and to a lesser degree A6s-A9s). Keeping the middle suited connecters in as bluffs is fine if you are able to dance around the danger postflop when it occurs obviously.

So anyway, vs an aggressive regular (who is pretty unlikely to trap over pairs) this is probably close. He has to have bluffs here and his missed draws can have some good blocking effects to you having a straight. A8s, A9s, K9s, etc. An aggressive regular can probably go for 3 streets on this board with a trapped over pair too (if he ever does this).

With good reads, you could potentially fold turn. That 4x on the flop and then 1/2 on turn has some characteristics to it that make me suspicious here.

Versus aggressive fish, I might just jam flop. Vs passive fish who's lightest raise here is AJ and doesn't raise many flush draws, I think your line is fine.

If villain is super aggro calling river seems fine. I'd expect villain to simply shove his high to medium equity bluffs on the turn which makes this line strange.

thats really good point that with bluffs most of the players don t use this turn sizing....
