SH Speed TJo Two Pairs Facing Check/Raise

It's really up to you to estimate his range, but here is an example from Equilab where the BB has solid value only.

Board: 7♦J♠T♠ 4♦
       Equity     Win     Tie
CO     34.25%  21.76%  12.50% { JhTd }
BB     65.75%  53.25%  12.50% { JJ-TT, 77, JTs, 98s, JTo, AhJd, AsJd, AcJd }

Note he has 3 combos of AJ that you beat. That is enough for a mathematical call. I let him fold 98o preflop. If he has those, things get worse:

Board: 7♦J♠T♠ 4♦
       Equity     Win     Tie
CO     23.50%  16.35%   7.15% { JhTd }
BB     76.50%  69.36%   7.15% { JJ-TT, 77, JTs, 98s, JTo, 98o, AhJd, AsJd, AcJd }

Bad!

But now also let him have ALL AJ:

Board: 7♦J♠T♠ 4♦
       Equity     Win     Tie
CO     33.49%  27.43%   6.06% { JhTd }
BB     66.51%  60.44%   6.06% { JJ-TT, 77, AJs, JTs, 98s, AJo, JTo, 98o }

That's back to calling (getting 2:1)!

Note, not a single semi-bluff in his range, only what he might perceive as value. I think top 2 is too strong to fold 100bb deep, especially on the turn on a draw-heavy board. Only a read could make me do that. Phrases like "they always have a set when they do that" aren't always trustworthy, since "when they do that" refers to a wide range of things depending on who is uttering the words. In my experience, it is often more frightening when they check-raise turn (which, by the way makes ME play like BB here with the nuts because I don't want to be believed then).

Not saying these ranges are realistic (wouldn't he raise JJ/TT preflop, and so on), I just want to illustrate that if he is capable of betting non-nuts hard and also bluffing just a little bit, then you must consider calling or shoving in spots like these with top 2 and 4 outs.

His line and the huge bets he makes look like only for value...

Good points by other posters but don't forget your stack size 146bb would be very spewey to gamble with
I don't like the call to re-evaluate. What cards are you hoping to see hoping not to see . At nl5 players are pretty straight forward his big check raise indicates value so fold and move on, and if he is bluffing well done him fold and move on.

A good rule of thumb unknown =typical player at limit (until proved otherwise)

I think I would have to discuss this hand with the coach. I remember having the similar hand before, where the coaches here told to call the flop. Two things could happen that are good for us if we call: 1) We could hit a fullhouse on the turn, 2) They could check the turn. I personally think that it's too weak to fold this flop, despite of the sizing, and 3betting would probably be an overplay, but is an option on this kind of board. From my experience, typical NL5 players at iPoker are not that honest and straightforward that I could assume that he is doing that only with sets or straights. He could have some bluffs and also top pairs, as YohanN7 said. Maybe would be ok to call missed draws on the turn and river, also. But not that sizing, imo.

i would say at poker stars this would be a very very close fold, at ipoker its a call,, lately at ipoker this kind of raises is normal from some regs with draws so at the end its all about your notes at this player

Maybe it's because only humans play at PokerStars.

really?? had no clueeeeee

You may be right (all of you), but there are also more variants given on the theme I was ranting about in my first post: I wrote

Phrases like "they always have a set when they do that" aren't always trustworthy, since "when they do that" refers to a wide range of things depending on who is uttering the words.

Summing up all these coherently means that players never ever bluff. Good player bluff. Good players bluffing BIG should have (according to the simplest GTO models) proportionally MORE bluffs in their mix. For simplicity, let this be the last bet this hand.

He should be bluffing 33% of the times here.

Bad players bluff too.

I argue that folding the very top of the bluff catching range (having outs as well) can't be right in general. It is super easy to exploit. [HINT: In the BB, take this line EVERY HAND. Your opponent has better than top two pair 0.00064% of the time.] You may still be right that players here and there "always have it" when they do "this and that". But then they are horrible indeed.

My advice then is play as close to GTO as you can until you have just one or two notes on the player. Then exploit. I'm not 100% sure that GTO says "don't fold" here, but I'm 99.5% sure. If GTO says so and they actually do have it 100% of the time, don't worry. They aren't exploiting you, you are automatically exploiting them when they don't happen to flop the nuts versus your top bluff catcher (which is the majority of the hands dealt).

The effective stack size is, b t w, 102bb, not 146bb as someone said.

Sorry 'bout spamming the thread guys, but one thing about GTO worth a separate post here is that GTO doesn't give the %# &¤ about your opponents range. It cares about the board, the action, the stacks, and your precise holding. No strategy beats it by definition, and GTO exists by proof of Nash. The only problem with GTO is that we don't know exactly what it says here or anywhere (except for a good approximation in FL HU, search net for "Cepheus poker"). The intuition though, is that top bluff catchers just cannot be folded under GTO. Such folds belong to the more human (and more profitable) exploitative area of poker.
