Regicide vs. Kokichi009 (I got destroyed)

I know that I made so many mistakes and had multiple opportunities in mating his king but some how it escape into safety and I had no more attacks left... This game was especially ugly for me.

> 22. P8gx8f

This lost the chance for material advantage. Instead, I think you could take the Silver on 7e without losing anything.

> 35. +B5ex3c

This trading Bishops was not good for you since the promoted Bishop on the central square worked much better than Gote's bishop on 4b. In general, It's not good to trade your well-working piece for your opponent's less-working piece. Instead of +B5ex3c, G*4d would keep your lead in that position.

> 39. R*8b

Very good Rook drop which forked the King and the kNight on 8e.

> 42. L*2f

This Lance drop was not the best move. Instead, I think P-2d would have been the best. If Gote took the Silver on 3g like +Px3g, then mate existed such as Px2c+ Gx2c Rx2c+(!) Kx2c B*4a P*3b N*1e K-3d B-5b+ P*4c +R-3e(mate). If Gote took it by Px2d, then sacrificing a pawn on 2c and N*1e would be a good attack to approach the King. If he took the Pawn like Sx2d, then Rx2d(!) would be good and then N*3d K-3c S*3e would let Gote have no defense. Please make sure that your promoted Rook on 8e worked horizontally extremely well to be ready for mating Gote's King from 40th to 47th moves.

> 47. P*2d

Not a best move. Instead, mate exist such as Rx2c+ Kx2c B*4a P*3b N*1e K-3d B-5b+ K-4d G*4e(mate)

> 50. +R-8d

Bad move. Instead, mate exists such as Bx2d+(!) Gx2d Rx2d(!) Kx2d S*3e K-1e G*2f K-1d G*2d(mate)

> 54. R2i-4i

I think this was the final point to lose the victory. Instead, S*3e K-3c N*4e would have been good then you could manage to win the game. Don't be afraid of losing your Rook too much in the endgame. After your Pawn on 3f was captured by Gote's Tokin, it's tough to win the game.

Ahh, thank you so much, Takodori-san. That game was mostly in pressure of the byo-yomi, plus it was one of my early games. It's often very hard to see these mad Rook and Bishop sacs because they were doing quite a good job in keeping the king in control.

I just don't know how to see these moves in a such short period of time (such as byo-yomi). Any tips?

And thanks again for the analysis!
