kapital is a semi-interactive monpoly bot. It's written in python and uses pygtk to display information about it's status and to accept raw monpod commands in the cases it can't handle.
At the moment it's designed for 1v1 bot vs bot games but it can be easily tweaked to play against humans. Check monopbot for the server IP/port, by default set to localhost:11234. One instance of the bot must be the player who creates the game named 'robotwar'. the player limit is to be found in monop/client.py :: Client::gameupdate() method.
The current strategy is very simple. It buys all properties it lands on and always pays out of jail. If there's ever a funding shortfall then it first mortgages properties that are not parts of monopolies in order for cheapest to most expensive. It will then mortgage properties that are parts of monopolies. Finally it sells levels of houses on developed monopolies. This procedure is iterative, so that after it has sold all houses on a developed monopoly then it will, as a last ditch effort, mortgage those properties.
When there is a surplus of cash it chooses to unmortgage estates, starting from the cheapest. If no etates are mortgaged then it buys levels of houses at a time whenever it can.
This has been tested against monopd 0.9.3. There is a bug in monopd on 64bit builds which causes incorrect estate prices to be sent to the client. This causes erroneous behaviour in the bot which relies on the correct values, unlike a human player who can read the descriptive display text sent over the wire. The following patch fixes the issue.

}The bot needs to handle auctions, going in to debt due to chance/community chest cards and trading.
