- bdendgame shows the format for getting the program to solve an
endgame. Note this is a Sowpods game, so be sure to chose
**sowpods**from the dictionary menu, and to press the "" button.`Perform exhaustive endgame analysis`

- bdsim2 shows the format for Monte Carlo simulations. This one is
again
**sowpods**. There are two ways to do simulations: you can do n-move lookaheads, or complete-game sims.

- I've made bdsim2 be for 2-move lookaheads (this is done with the
"sd 4" command, where 4 is the number of 1/2 moves you wish to look
ahead.) The length of the sim is 40,000 iterations ("sl 40000"), and
in this case our rack is in "r0 ABLLOSU". If some or all of the
opponent's rack were known, e.g., due to losing a turn when they
played a phony, we could have "r1 xxx" where xxx are opp's known tiles
-- the simulator will place those known tiles on opp's rack when
choosing random racks for opp. Pressing "
" is equivalent to the command line "`Run sims to given ply depth``simul -ldd s bdsim2`".

- To play out games to the end, press the "
" button. This is equivalent to the command line "`Run sims to end of game``simul -ldd p 10000 bdsim2 | countwins -n 4 -p 4000`", which will play out 10,000 games to the end and produce log2s of the result. The pipe command and "countwins" are a perl script which summarizes the results: it knows there are 4 moves being simulated ("`-n 4`"), and it will print out an intermediate set of results every 4,000 log2s ("`-p 4000`", which corresponds to 1,000 games with each of the 4 moves).

- bdblank is a blank file you can use to start your own input file. However I recommend using the web front end, which makes input easier and still produces a suitable file for you - it's easier than creating one with a text editor.

Here is some sample output from the command-line version:
