I took the photo.
The guy immediately in front of me is the dive master.

My avatar is a whale shark I was lucky enough to see on a dive last year. Apparently it was a juvenile and so it was "small". A truly amazing fish.

Nah, just snorkeling ... scuba diving is for next time

My time to be slow. I've been playing lots of chess recently in preparation for the summer tournament cycle, so I blame chess. Anyway, I'll make my move over the weekend.

Maybe something like this?

This result looks terrible for White, so this is probably not what EdLee has in mind. I got to think some more.

I was very close to making a move numerous times. However, I kept finding previously overlooked resources, thus delaying my response. There were several issues I tried to fathom. Firstly, I attempted to decide between the game continuation and this alternative:

Click Here To Show Diagram Code: [go]$$Bc $$ | . . . . . . . . . $$ | . . . . . . . . . $$ | . . O , . . . . . $$ | . . . . . . . . . $$ | . . B . 1 B O . . $$ | . . . . . O X . O $$ | . . . . . . . . . $$ | . . . . . . . . . $$ | . . . O O . . . . $$ | . . X X . . . . X $$ | . . . . . . . . . $$ | . . . . . . . . . $$ -------------------[/go]

This move links up the marked stones better than the move in the game. Yet, these stones seem to be at risk of getting separated from other Black stones in many of the variations I looked at. As such, the move in the game--which offers better access to the center--is preferable.

The question is, however, whether White can take advantage of the gap between Black stones. To this effect, White can try the following moves, for example:

I think I can get a reasonable result in all these cases.

Secondly, I tried to understand what happens if I try to run the G7 stone if it gets ataried. The consequences of the following variation seem disadvantageous--very risky, in the very least:

O , . . . . . , . . . . . X O . . | $$ | . . . . . X 5 . . . . . . . . . O . . | $$ | . . X . . X O 4 . . O . . . . . . . . | $$ | . . . . . O X 2 O . X O O O . O . . . | $$ | . . . . . . 1 3 . .

X . . . | $$ | . . . . . . . . . . . . . . . . . . . | $$ | . . . . . . . . . . . . . . . . . . . | $$ -----------------------------------------[/go]

However, Black can play the following move, so Black should be fine in case of the immediate atari by White:

Finally, I tried to understand whether I should or should not respond to :w1:

(which threatens the corner) in the next diagram.

As the variation shows, if Black ignores the threat of :w1:

, Black has a ko for life. This ko is risky, but maybe tenuki could prove more valuable. Currently, I'm undecided on the subject. I'll think more about it should the possibility materialize on the board.

Now I need to make sure I did not miscalculate earlier in thinking that I can play the following move (or that I am not missing an even stronger reply):

The Intrepid, just checking: you know it's your turn, right?

Yeah, I know, sorry! :oops:

I was preparing for a major chess tournament, then played in it for a week (doing reasonably well), and now I'm recovering from it ... still not quite in the mood for hard-core Go reading ... but I'm getting there

Wow, chess tourney! Exciting. How did you do? Too bad you cannot post your chess games here... or, can you?
Can this forum support chess SGF files???
