Playing Ax (2-10) is not one of my strengths. Preflop, I will tend to fold in EP, call in MP and call or raise LP. This sounds too predictable, but that's the way I often play. And I will often fold to an early position raise.

Postflop, I will check or bet if an ace flops, depending on number of players, whether there was a preflop raise, and other various random considerations.

So on to an actual hand:

At this point me (at about 2180) and villain (about 1200) are aware of each others tendencies. Villian is generally TAG. I get A3 in the BB.
Two other limpers plus villain and I rap the table.

Flop is A64, rainbow with one diamond. I bet 20 and only villain calls. Turn is the 7. I bet 30 and villain raises to 85.

So what are those tendencies?

In the hand posted, I'd fold. I'd also probably check/call the flop. Or possibly fold the flop if there's a ton of action. Being OOP sucks.

When you bet 20 and V calls, what does that generally mean?

When villain raises to 85 here, what does that mean?

How often do you fold to pressure vs this villain?

Does villain go away when you show strength?

Can/Does villain fold TPMK or TPWK or even TPGK type hands when facing pressure?

What position did V limp from? If he had an Ace in this position, what is his likely kicker given that he limped from that position?

The above needs to be answered in regards to the optimal way to play Ace rag vs a villain you have history with.

As played in a vacuum, this is a trivial fold.

I think donking this flop doesn't accomplish much. When you get called, you are most likely behind vs. Ax with a better kicker. If the flop was two-tone then that changes things a bit, and I know that even on this rainbow board you CAN get called by 75, 88, and hands like that, but majority of their calling range are better Ax hands.

You said A64r and the turn brings a second , but which card on the flop was a ? That has a pretty significant impact on the hand and the villain's range (whether he can have Ax of 's or not, or a straightflush draw).

This. My standard line here is check call flop against one player or even check fold depending on reads but definitely check fold against a bet and a call. U can then check fold turn. U can't really go wrong just check folding flop every time here tho. It's exploitable but few are exploiting u for that
