102. △R*5h, White dropped a Rook on 5h threatmating Black's King.
101. ▲B*4d, Black dropped a Bishop on 4d. The question was whether it was a threatmate or not?

99. △+Nx5b, Black took the Gold on 5b.
98. △P*4b, White dropped a defensive pawn on 4b to take the promoted kNight on 4c.

95. ▲N*3e, It's a threatmate to begin with ▲B*5c.

64.R-5i+(!), △Hmmn, White promoted his Rook but it's just a sacrifice.
63. ▲R-6e, Black let his Rook escaped to 6e threatening to take the kNight on 7e. He could take a Rook, Bishop or kNight soon.

54. △B*8h, White dropped a Bishop on 8h which would try to take the Lance, connect with the Silver on 2b and protect the head of the Rook.
53. ▲Rx6g, Black took the promoted Silver by the Rook.
52. △Sx6g+ White took the Gold with Silver promotion. His vertical line of the Rook became open.

49. ▲R-7g, Black let his Rook go back to 7g.
48. △P*7e, White's counterattack started with this pawn drop. If Black took it by Rx7e, the game would end by B*6f(forking King and Rook)!

46. △R-5d, White let his Rook escape from the Bishop.
45. B*6d, Black dropped a Bishop which was forking Black's Rook and kNight.

@hidetchi 伝統的な格言ではないですが、「わからんときは取れ」は実践的だと思います。
41. Kubo showed his intention to make a sealed move.
40. △Sx5f, White took the pawn. Now, both Bihsops are facing each other.
39. ▲P-5f(!). Black tried to make another pawn sacrifice by advancing it to the head of the Silver on 5e.

38. △R-5d, White Rook escaped to the central file. His right kNight could take the Pawn on 6e in need.
37. ▲P-6e(!), Black tried to sacrifice the pawn on the 6th file. If White took it by △Nx6e, it would be killed by ▲P*6f.

35. ▲Px6f, Black responded it naturally to take it.
34. △P-6f, White tried to block the diagonal line of Black's Bishop with this pawn sacrifice.
33. ▲S-6h, Black pulled back his right Silver again. It moved from 6f to 6h. As a result, his Bishop started to work better.
32. △S-5e, White advanced his right Silver to 5e to dominate the central area.
31. ▲S-7g, It's a natural move. Black could not lose a Silver in this early stage.
30. △P*6e, White dropped a pawn on the head of Black's Silver on 6f.
29. ▲P-9f, The intention of this move it to move Black's Bishop to 9g to threaten to take the Rook on 6d.
28. △Px7d, It's a natural move to take the pawn.
27. ▲P-7d!, In spite of White's previous △R-6d, Black made a sacrifice of a Pawn on the 7th file.
26. △R-6d, White prevented Black's Rook pawn trade on 7d with this Rook's move.
25. ▲P*6g, Black seemed to calm down the situation with this pawn drop to support the Silver on 6f.

23.▲G-7h, Black's Bishop got connected with the Gold with this move.

20. △Px6f, White took the pawn on 6f by his Pawn.
19. ▲S-6g, Black increased the protection on the square of 6f with this Silver advancement.
18. △P-6e, Suddenly White entered into hostilities. If Black took it, he would lose his Bishop by △Bx8h+
17. ▲R-7f, Black prevented White's Rook pawn trade by floating his Rook to 7f which is called Ishida Style.
16. △P-8e, White advanced his Rook pawn again to trade it on 8f.
15. ▲S-6h, Black advanced his left Silver to 6h. Rookside Silver is usually needed to advance to the third row to build good formation.
14. △P-8d, White finally advanced his Rook pawn.
13. ▲K-3i, Black continue building his castle.
12. G6a-5b, White moved his right Gold to 5b. It's a little surprise to me since this right Gold move seems a bit early.
11. S-3h, Black moved up his right Silver to 3h. It turned out that he would adopt Minogakoi as his castle and gave up Anaguma.

9. K-4h, Black also started to move his King to the opposite side of his Rook.

7. R-7h, Black transferred his Rook to the 7th file to secure the vanguard pawn on 7e.
6. S-6b, White moved his right Silver since no possibility of quick attack after Bishop trade.
5.P-6f, Black blocked the diagonal line of his Bishop by himself with this pawn advancement.
4. K-4b, White moved the King to 4b before moving his right Silver to 6b. Against Ishida Style, this early King's move is considered better.
As to Ishida Style, good article is available to read in Shogipedia at http://bit.ly/7Z1E8Z
3. P-7e, Black advanced vanguard pawn on the 7th file so early. His intention seems to adopt Ishida Style Sangenbisha(3rd file Rook).
2. P-3d, Habu responded it by opening his Bishop's diagonal line, too.
1.P-7f, As a result of Furigoma(Five Pawn toss), Kubo became Sente. He opened the diagonal line of his Bishop.
