Notes:

1. Should Hero reraise turn?
2. Should Hero bet river to fold out Qx?

Bet flop bigger

Definitely don’t 3bet turn

How on earth can villain have Qx as played

C/f river

+1

What does villain have?

+2

Depending how often villain 3bets preflop he can raise turn with some or all of: AA, QQ, KJ, TX, AQ, AK/AJ, AXcc, KXcc

He probably just flats (or folds) his weaker pairs to your turn bet: KK, QX, JJ and 99-

If you 3bet turn you'll isolate yourself against boats, KJ and his combo draws. I.e. you'll fold out all the hands you have the most equity against and you'll get called by hands you're drawing dead against or that have a lot of equity against you.

Hero should never check Ax here, correct?

Checking means surrendering 100%.

Check the turn - that T is one of the worst cards in the deck for you, if not the worst.

How come?

I'd go slightly higher on the flop. Turn is fine -- don't raise.

River is a check/fold, unfortunately.

If your strategy means that checking means you're 100% surrendering the hand then you have a problem. Your observant opponents will start taking advantage of you by betting every time you check, regardless of what they hold.

So, for example, if I were opening this pot from hijack preflop I could have any suited ace and any offsuit ace down to AT (depending on the situation). So I'm going to have a lot of AX on this flop as well as a lot of other strong hands and decent draws.

Nevertheless I'm going to have to check some hands I opened preflop (99-22 and various suited connectors that totally missed). If I don't check these hands my cbet range becomes obviously too wide and weak. If I'm checking hands I won't continue I must check some hands I will continue.

Thus I'll check some weak top pairs (AX), KK, second pair and some draws. Occasionally I'll check a strong hand too. Then if villain bets after my check I can call some hands and raise (for value or as a semibluff) with others. That protects my checking range from cheap exploitative attack.

This is necessary against any modestly observant opponent vwith any poker ability whatsoever.

Tc is a bad card for you on turn because low stakes players often have all combos of AT and QT after flatting preflop and flatting turn.

Additionally you block some combos of KT and JT (the TX you're happy for villain to hold. Villain could raise a TX hand that you beat but you could end up folding the winning hand because he does same with his boats.

Low stakes villains cannot be relied on to 3bet preflop with QQ- so can potentially have Querns full or quads here.

Some of villains range for calling the flop will also be spades (one pair with AXcc, gutshot floats with KXcc and JXcc). These hands gain extra equity against you as they are now drawing to a flush to beat you as well as a small number of outs to chop the pot.

So overall villain's range is greatly strengthened by the Tc on turn and it becomes questionable how much value you can get from a turn bet and there's a risk of getting raised and folding the best hand.

That's not what I meant at all.

I meant if we check here, there is no scenario where we call or raise a bet from V.

I don't follow you. Please expand on your reasoning...
