1 - Whats the hand for? You fold preflop or fold flop, simple.
2 - Preflop is fine. Flop jut shove over. Screw leaving 900back.
3 - You had no chips, nothing u can do
I so miss my "lil" british donk!
I know I suck but only 160 to call on the 8 10, and as Pan said donk woulda probally called a shove anyways, and I had more chips than him.
