Remember the game with the pae [패; ko] fight, and – what I thought at the time to be – a great maek [맥; tesuji]? Here is the gibo [기보; kifu] again to refresh your memory:
If you want my initial comments, here is the blogpost where I review my own game. But I am really sad… because in reviewing this at the club evening yesterday, I was unequivocally told that my great play at B1 was basically kicking a dead corpse after I killed it; apart from being just very very disrespectful, it lost me the pae fight… 149 was an exchange instead of a threat, and any air of greatness I felt after playing it – and the supposed B1 follow-up – evaporated into thin air. What is also interesting is that, according to The Kibitzer, it was only after I responded with 147 to 146 in the first round of threats, that the pae fight became really valuable; I guess it has something to do with the fact that otherwise White can still run.
Another lesson they instilled on me in the review was the fact that I had more threats on the board, so the exchange with Black 149 is not a good one; it gets me 30 points tops, but winning the pae fight would have gotten me more as well as seonsu [선수; sente] if White wanted to save the corner. Either way, the outcome would have been better for Black if I had not played 149, but saved that for last if White had more threats than I did (which she didn’t, apparently). The reason I had more threats is the following sequence, or at least it is a sequence of threats that would set up a new one for Black every time, and if played out will can give at least six from what was initially just one. Basically, after I played A as a threat, white answered with B; my next threat should be at C, which White needs to respond with D; next threat at E, with white playing at C to connect; then the next threat is at F, with white having to dansu [단수; atari] by playing G; then the next threat is to descend with H, and White needs to respond at I; then a threat at J, and white has to capture; then a throw in at F, which is the last clear threat there, and white responds by playing H. Including the threat that I had played in the game (A), the area can provide seven threats for Black, which is an edge in a pae fight. It is sequences like that that I have a hard time spotting.
So lessons learned:
- Read out what happens when you don’t play a maek, perhaps it is already dead
- Pae threats are only threats if the opponent has to respond, killing something is not a threat (it, in fact, is murder)
- Think through pae threats; and don’t approach them on a one-by-one basis, but try to find a way to play it so you can force your opponent to respond where you want them to respond.
- How does the board look after your opponents response? is it beneficial? are there follow-up threats? or follow-ups even after the fight is over…
- Calculate the value of the pae fight, and see if an exchange is better or not; also make sure that your threats are big enough in terms of potential point value
