Black just has to simplify the game and coast to a win.];W[qj](;B[pj]C[I don't know the proper move here. Was connecting under better ?===Yes. Basically, white has influence out there to attack you with. You'd rather settle and live locally, than run out, and have white actually be able to use his influence.

Can it even live? If not, you're bleeding your lead away.];W[ge];B[ie];W[gf];B[eb](;W[jg];B[jd];W[kh];B[ic]C[This felt bigger than defending the two stones.===The two stones are worth 5 points right off the bat (4 for capture, +1 for K12) Furthermore they set up N13, which is a 4 point gote move for either side. Either side has a 50/50 chance of getting it, so that's considered a further 2 points. So it's about 7 points, plus a tiny bit more depending on what happens if white also captures n12.J17 is big, probably worth it, so I think you're correct, but I wanted to make sure you knew that M11 is also valuable, maybe more-so than it seems.];W[lh](;B[qb]C[===This move is odd, it's like S18, but worth a few points less. See the variation for a way to count it.];W[kf];B[le]C[same Idea. The two stones are 4 pts gote if I count well.===You mean N12? It's immediately 4 points, but there's the M14 gote followup which both sides have a 50/50 chance of getting. M14 has even more risky dangerous business, and at the very least white can then push at L15 in sente for a point. So the value is more like 6.5 or so. Still, I'm not saying that you choosing not to save them is bad, but it's worth more than you think.];W[mg](;B[kr]C[still the same idea. In the end, it was probably a little too much ?===Again, there are weaknesses left behind after white M14. That being said, L2 is pretty big. BTW, S1 would be sente if black had more ko threats. S1 would be worth about 6 points then, as white r1 is sente for him.Also, if the G8 area was left as it was with all the potential threats, then S1 would certainly be dangerous for white to ignore.];W[lf];B[oe];W[ke];B[ld]C[===So you see that it was more than just 4 points.];W[hd]C[===Now, K15 is 6 points. S1 is also 6, but S1 is more interesting for you, as you can set up a ko later. The threat of a ko later would possibly cause white to have to at some time come back to fix it, as black's O10 ko threats aren't going away. See variation.](;B[je];W[ja]LB[ha:2][ka:1][jb:3]TR[ib]SQ[kb]C[===So, in short, to handle a monkey jump, there are usually 3 standard moves. They are numbered in their preferred order. Sometimes triangle can be used, and sometimes you just have to play square. J17 is very rarely a good call. There are sometimes cases, but it should be considered last.Here 1 and 2 don't work, so you can go with 3. See variation.](;B[ia];W[ib];B[jb];W[ha];B[ka]C[===Also, if white wants to end in sente, white can stop here, glad that he reduced black in sente. He can come back to fill the ko later after he's taken some other big sente points, such as R1.];W[ia]C[===The difference is that white can play H17 for a point later. The ko is big enough that it would probably be sente later on, so we should count H18 as an assured point for white. Also, K17 is certainly not a point for black now, while in the other variation it had a chance of being one. So that's 1.5 points difference, plus one because white captured a stone. 2.5 points overall difference to the variation. But you also have to add in whatever might happen if white tenuki instead of J19, as that ko isn't worth filling yet with juicy sente like R1. The difference might be larger, as white could play bigger moves before J19.If you're more interested in monkey jumps, Guo Juan's website has two lectures on them (the first explains responses, the second is more so just problems and examples). It's probably worth the $1 (well, 1 euro) price. There is also a book I believe on them, but I'm not familiar with it. I am in no way affiliated with Guo Juan nor do I advertise for her :)];B[rb];W[me];B[ne];W[kd];B[lc];W[qs];B[pr];W[ps];B[os];W[rs];B[or];W[hc];B[jc];W[qd];B[sb];W[pe];B[on]C[===Now that white can live locally, this isn't worth anything.];W[oo];B[no](;W[so]C[===So you played P6 and O5, which didn't reduce white's points, and white played T5 then, which increased his points. Also, white could of played T6 to actually reduce you too, with R6 being a further point with a threat of a ko for more points. All in all you would lose a few point through all this.];B[sn];W[mo];B[qn]C[free move for white.

However, there were several times where you could of made a different move to accomplish the same purpose that would help counter white's influence, but didn't go for it. That might be a lack of whole-board sight or thinking. Later on, you had a comfortable lead, but started getting jealous of white's center, even though it was small. You even made some desperate moves to try to reduce it further, but those got cut off losing you many points. Not only did those get cut off, but they paved the way for white to make many reductions and small captures. Through that, and other miscellaneous mistakes In the endgame, you gave up about 20+ points of your lead.Key points to work on:1) Think and see more in the whole board. If there's multiple moves to accomplish the same purpose, try to find ones that have a more global value, such as helping with the balance of power.2) Don't get so jealous of your opponent's territory even when it is not enough, but try to count and maintain the balance.3) Study more of the endgame, or else be more careful. One of the elementary series of go books is on the endgame, and you might find it valuable.])(;B[jr]C[===White is 1 point smaller, and you'll still get L1 later. Furthermore, K1 is sente for you, so you'll probably get it right away. If white takes it, it's gote and you'll just snatch up one of the other gote moves that's worth points.]))(;W[sn];B[sm];W[so]))(;B[jb];W[ia];B[ka];W[hb];B[ib];W[ha]C[===White has no points there, and you have a 50/50 chance of making K17 be a point.]))(;B[rs];W[je];B[on];W[oo];B[no];W[mo];B[np];W[om]))(;B[rs]C[===If black had more ko threats, this would be big and sente.]))(;B[rb]TR[sd][re][se]C[===Bigger than R18. 3 points or more difference actually. Let's count it.Like this, white can hope to get no more than 2-3 points around the triangles. If black played R18 instead of S18, it would be the same if black came back to turn at S18, but there's a good chance white will get S18 for himself. If that's the case, then white immediately gets 1 more point of territory. Also, white S18 sets up R19 sente, which is worth 3 points in sente.Let's go over that again, if black R18, then S18 is gote for both sides. Let's simplify and say both sides have a 50/50 chance of getting it. S18 decides if white gets T17 as a point, so that's 1 for now. White S18 makes R19 sente, so white will waste no time in taking the sente 4 points (2 territory for him, minus 2 for black). If black blows sente to make up for this, white gets a gote move elsewhere of comparable value. Now, look at black having S18. He's probably going to get R19 as a point, so that brings the total value to 6 points difference between black S18 and R18, to go to whoever get S18. So it's 3 points if you think that either side has a 50/50 chance at it.];W[sb];B[qb]))(;W[je]C[===White can just kill these stones too. 4 point capture + 1 or 2 points in territory he wouldn't of had, it could be another loss of 5 points through carelessness.]))(;W[jb]))(;B[ji]C[===Make yourself a strong group, especially after having lost the liberty with O12.];W[jj];B[ii];W[ij];B[nl];W[ml];B[ib];W[qb];B[pb];W[rb];B[pe]C[===White cannot make up the 25 points or so he's behind.];W[qs];B[pr];W[ps];B[os];W[rs];B[nr];W[kr];B[lr]))(;W[kh];B[lh];W[li];B[kg];W[jh];B[lo];W[kn];B[kc]C[===The game is hopeless for white.]))(;B[ok]C[===This is called the driving tesuji.
