I was playing last night weird hand in my opinion.
As big blind I limped/called in limp-limp m-w hand..

Flop: 2 3 4 r

It went c-c... and someone bet small into low pot, I called w/ 67o...

Turn: 5 r

I bet like 2/3 into pot after one check (cca $30) and short stack guy behind me went AI w/last $60. One more player (small blind) wanted to call and then asked dealer and others:

• how much can he bet max
• who else is in pot (it was only me left)
• what's my action after he plays hand?

Conclusion was that he could only call as short stack guy did not have min(2 * my bet) so after he could just call I was also allowed to just call if 2nd player decides to call this bet...
Is this correct?

So we both just called and now pot was cca $250.

River: 2 3 4 5 3

Small blind bets $40 - what do you do here..?
We have cca $250 left, villain covers us...
