Does the bot remove itself from the table? Does Ignition remove the 'player' from the table automatically? I'm thinking about the stealth issue. A human player would buy-in again or quit. Since gambler's ruin makes this an eventuality for even a good bot, there's must be a solution to obfuscate the presence of the bot for this situation.
The last two times I logged onto Ignition I experienced an unusual event. The 'Sit out next hand' check box was automatically selected, that is it checked itself on. Both times this occurred I was playing cash games, once an NL table, the other was low limit. On the first occurrence I kept unchecking the option to continue playing the bot. The second occurrence I left it checked to see what would happen. The site removed me from the table sighting the 'You missed 3 BBs rule'. I was logged on for just a few minutes so I doubt it was the Holdem bot taking a pee break.
The thought crossed my mind that perhaps this was Ignition's way of testing for a bot. I'm just guessing here. I play with the bot window hidden, exposing it only to hit the start.
