Nice to see another brit posting here.

1) Villain has a big stack and I don't think you have enough chips to make him fold. I like the move though, just maybe this isnt the best spot for it.

2) 500 pre, rest is OK.

3) Fine. There's a good chapter in NLHET&P on HU push fold poker, or you can google the SAGE system.

How many tables are you playing at a time?
