When im fairly certain that my opponent has aces and I have hit a pair with my rundown is it profitable to chase two pair for all of my stack (100 bb), when i also have some backdoor escape valves like backdoor fl, str draws.

If i flop fl draw+gutter with aces to me its the nuts, but is it profitable in SH to get most of money in on turn when your flop pot bet has been called HU/3-way/4-way, or should i slow things down, cause im probably against a set or two pair.

What boards are good to contibet and which not? (HU, 3-way, ..)
Main SH concepts, and on which limit the games turn a lot tougher?

What tracker programs would you recommend for Omaha?
