Suppose you're Black. How much komi would you pay to be able to play this brick as your first move?

(I had this idea at the last Congress - I found someone to play it out with me, and I wound up killing the brick.)

-6.5, you'd have to pay me to have that eyesore on the board.

I am far from an expert but I think your experience kind of highlights it... that brick looks pretty heavy, and I'm not sure the power in the corner is worth more than its liability.

I would pay..

Area or territory scoring? It's worth more with area scoring.

20 with territory, 32 with area, not only does it have miai for extensions, but if they try to approach from either side you have massive endgame play

If I can play this brick as a first move, then I suppose I can play it anywhere on the board, right?

It reminds me of a Thwomp from Super Mario Brothers. It could be useful if carefully placed.

My idea was to have it stuck in the corner.

@skydyr - it's a lot thicker than it looks (which is pretty thick, I guess). The guy with the brick played tenuki a lot of times before I was even able to get a ko.

It seems logical that the difference between your numbers equals the number of black stones. Or does it imply that you are sure that black won't sacrify the lump?

Black might sacrifice the lump, but if he does, he ought to get something bigger. It's too resilient to be a liability.

Go is such a beautiful game.

When y'all say 20, does that include standard komi, or is it on top of that?

It's a very odd position to evaluate. My feeling is if komi <= 23.5 I take Black otherwise I take White.

Yes 23.6 is just too much..

I wouldn't be surprised if the 'correct' answer is anywhere between 13 - 33.

I also think the correct komi probably changes a little depending on the strength of the players.

When I say 20, I'm including standard komi

I would prefer black if white had less than 30 komi (with territory scoring).

This reminds me of a game I once watched a couple friends play....instead of having a 4H or so they would usually play with, they tried a 15 stone handicap, free placement...under the condition that white gets to place the stones. ended up with a 3x5 lump very similar to this.

Since I would only be echoing the opinions of others on the komi (I'd say ~26.5), what about this thought exercise - how many moves in a row would you want as white if you had to kill it?

I think 5 should be straightforward....4 might get tricky though...
