Hand 1:

Preflop OK. preflop call by villain indicates small-mid pockets.

Flop bet ok. Yellow light to get call.

Turn bet is donk play. No reason to go allin here. I am already
alerted by flop call because there is no draws so only reason
to call is set. I would bet 5 and check river.

Hand 2.

Small stack nightmare?

Preflop ok:

I cant put button on hand but it could be anything from
two pair to fl. Against short stack I think I would have called
too. As played I would put villain of fl draw and call him down.
