25NL - A4o facing overbet from loose villain

[Triggerle]

Overbet is often an overpair. This goes with the TT hand you observed.

You only have a small TPTK and a gutshot draw. This leaves you in bad shape if he really has an overpair as the odds are far from right to draw.

Your hand is also extremely vulnerable if he doesn't have an overpair since almost any turn card will turn your hand into middle pair.

Just let it go.
