A Shogi game always starts with a +1.6 advantage, which means that Sente has a slight advantage to Gote at the start of the game. If the was Chess (or a chess variant in lichess), a +1.6 advantage would literally mean that you’d need to be about 50-100 ELO higher than your opponent to win easily, but in shogi it isn’t the same.

Here’s a game between YaneuraOu v6.0.0 running with Suisho [...]1S-48-0.5For the 1st move, YaneuraOu suggest either of the following lines to maintain the advantage at the start of the game.

1. P-7f 2. K-4b 3. G4i-5h 4. P-8d 5. P-4f 6. P-8e 7. B-7g 8. R-8d 9. B-6f 10. R-2d
+1.6 advantage

1. P-2f 2. P-3d 3. G4i-5h 4. K-4b 5. P-7f 6. G-3b 7. P-2e 8. B-3c 9. Bx3c= 10. Nx3c
+1.6 advantage

1. P-4f 2. P-3d 3. R-4h 4. S-7b 5. G4i-5h 6. P-6d 7. K-4i 8. S-6c 9. S-3 [...]2P-340.03P-76-0.2Over here it is understood that in the progress of the game, the Bishops would be exchanged and it is likely that Gote advances the pawn in P-8c.4P-84-0.45P-46-0.66P-85-0.47G-78-1.1G-h7 prepares/protects the Bishop for an exchange in case the pawn advances to 8f.8P-86-0.79Px86-1.410Rx86-0.8The pawn exchange even helped Gote to get a reasonable attack and threat for promotion. This is where Bishops need to be exchanged and the pawn in the pocket can be brought back on the board. This wasn’t done though and instead the Silver General was pushed ahead to defend the pawn at 4f.11S-47-0.911.Bx22+12.Sx2213.P*8713.B*7712G-32-1.0Gote is preparing/protecting from an exchange now.13P-36-1.114K-42+0.315P*87-0.8Sente drops the pawn on 8g attacking the room and attempting to make it drop down from its attacking stance, but the rook can take the free pawn lying in 7f.16Rx76-0.717Bx22+-0.918Sx22-0.7Bishops are finally exchanged here, but Sente immediately drop it back on the board giving Gote a promotion threat, though it can easily be defended.19B*83-1.020S-72-1.3Gote prevents the Bishop from taking any pieces, but the promotion can’t be stopped here.21B-65+-1.7At this position, surprisingly YaneuraOu v6 (shoginet) says that Gote is slightly leading with a -1.1 advantage. Though Sente has many attacks on Gote and even directly attacking the rook, which can’t promote here.22R-74-0.523P-66-0.924B*83+0.8Gote strategically drop a Bishop at 8c. This provides Gote an opportunity to attack the promoted Bishop Sente has, leaving Sente’s promoted Bishop with no other choice, other that to either wait and exchange bishops or exchange the promoted bishop for a rook.25+Bx74-0.126Px74+0.927G-48-0.628B*33-0.5Gote drop the Bishop at 3c attacking the pawn at 6f. To defend this pawn, Sente would have to advance the Gold General that is at 7h.29G-77-0.830N-73-0.731R-38-2.0Sente move the rook to 3h allowing the pawn at 3f to advance.32P-64-1.533P-35-1.834Px35-0.435Rx35+0.1Pawn exchange helps the rook attack the bishop ahead and threaten for a promotion.36P-240.037R-39-1.3Sente retreat the rook and even seems to be in a slightly weaker position right now.38P-650.0Advancing the pawn allows Gote to attack the pawn on 6f with both a bishop and a pawn. A pawn exchange from Sente can’t be done here as that provides a free piece for Gote and a promoted bishop.39N-37-0.240B-44-1.041N-45-1.8Advancing knight threatens for a promotion.42S-23+0.343Px65-1.444Nx65-1.3Pieces exchanged providing Gote various attacks on Sente’s Gold General and a high chance of piece promotion.45G-78-0.846P*37+1.5Here Gote drops a pawn at 3g. The first “inaccuracy” in the game. A better line would be promoting the bishop at 4d. This would even allow an attack on other pieces of Sente. This even gives Sente a chance to defend other pieces.46.Bx99+47.P*7348.S-8149.R*6350.G-5251.Rx65+52.L*6153.N*6454.Lx6455.+Rx6456.P*6357.+R-6558.+Bx8959.P*3360.G-3161.L*8662.B-9463.Lx81+47Rx37+0.148P*35?!+3.9It would have been suggested to drop this pawn at 3f instead of 3e attacking the rook.48.P*3649.Rx3650.P*3551.R-3852.Bx99+53.P*7354.Sx7355.R*6356.G-6257.Nx53+58.Gx5359.Rx73+60.B-9461.Rx3562.G-5463.+R-6264.P*5265.S*5149S-88+4.050B-66+6.351R*67+5.652B-75+7.053Rx65+5.554P-44?!+9.1Now Sente has a huge advantage after P-4d is played (+9.1). Engine suggests P-6d here. This positions seems pretty one sided now and Sente clearly has a lead.54.P*6455.R-5556.G-5257.Rx3558.P-4459.N*1560.P*3461.Nx23+62.Gx2363.R-3964.N*4365.R-5666.Px4567.Px4568.N-3569.S-5870.Nx27=71.R-4955P*73+9.356Sx73+9.657R-63=+9.2Rook underpromotes and attacks Gote’s Silver General, which once is taken, gives Sente an easy chance to attack other surrounding pieces. But this also leaves Gote’s pawn free to take Sente’s knight at 4e.58Px45+9.159Rx73=+6.360G-72+8.3Gold General attempts to stop the rook by attacking it and protecting it’s bishop. The best and most obvious move here would be for Sente to take the bishop at c8. An exchange of pieces.61Rx83=+7.062Gx83+6.863B*61+6.4Sente finds a free and comfy spot to drop the bishop. This even gives a promotion for Sente that Gote really might want to defend.64P*68+10.065S-58+6.966G-73?+15.1Mistake from Gote allows Sente’s bishop to further attack and even a slight chance of promotion.66.P-69+67.Sx6968.P*8269.Rx3570.R*2971.K-6872.N*5673.Px5674.Bx48+75.N*4467N*44+12.4Direct attack on the King.
