This seems clean and reasonable to me. (Or you could just as easily have the server do the adjustment and set Komi to 3.5; that would also be consistent with TT rules). If my bot sees 2 black moves in a row, it can figure out it's in a handicap game. A bigger question to me is, how

However, I will probably maintain the current scheduling algorithm which will make the larger mismatches fairly rare though not impossible. This will be good because it means we will still prefer non-handicap games, and I'm guessing that the vast majority of games will not be be large hendicap

My plan was to simply use the same scheduling algorithm I currently use. I would take the weaker base player and see if handicap versions of himself more closely matches the ELO rating needed to give an even game. I assume the same method of an updated engine connecting with a new login still

Okay. Don's later post does indicate that he intends to compensate for the stones. So, in the interest of being 100% clear: is this compensation included in the komi value that is sent to the client? Weston On 12/29/06, Weston Markham [EMAIL PROTECTED] wrote: Am I correct in inferring that

I agree with you. Weston's post convinced me that the program should know in advance what the handicap is to be and thus sending consecutive genmove commands is not really correct technically speaking. I don't like implied compensation, but apparently it is popular and KGS does it. However,

sorry, i just realized how out of context that was. in response to X is 50kyu, Y is 300kyu, etc. 30kyu is a good bottom end. the bottom has to be somewhere, and 30kyu humans are easily beaten by most anything stronger than random play. more than 39 levels is asking quite a bit of the ranking

There are 3 gtp commands for handling this: fixed_handicap place_free_handicap set_free_handicap You are arguing that fixed_handicap, even though it's quite explicit, is the wrong one to use in this situation? set_free_handicap would also work - the server just specifies the points and

To be honest, it seems very ugly to me but it seems to be what the majority like. Apparently KGS handles it this way, the program just has to magically know what the compensation is. But that's true of any handicap system, the program has to have the correct understanding. I think we had this
